Relaciones entre radiación solar, desarrollo y calidad de cactáceas ornamentales
Provedor de dados: Depósito Institucional Abierto de Documentos Digitales del Colegio de Postgraduados (COLPOS DIGITAL )
Autores: Sánchez Pérez, Anna Magali.
Las cactáceas tienen flores y características morfológicas atractivas que las hacen plantas  ornamentales muy apreciadas; se utilizan principalmente como ornato en exteriores pero  algunas también se pueden utilizar como plantas de interior; sin embargo, en interiores hay  bajos niveles de radiación fotosintéticamente activa (RFA), lo que influye en su crecimiento,  desarrollo y vida útil. En México hay poca investigación sobre el tema, por lo que el objetivo  de esta investigación fue analizar el efecto de diferentes niveles de RFA en el crecimiento,  periodo de floración y contenido de pigmentos (clorofila “a”, “b”, carotenoides y betalaínas)  en cuatro especies y analizar su capacidad de adaptación a bajos niveles de RFA.

A Floricaula/Leafy gene homolog is preferentially expressed in developing female cones of the tropical pine Pinus caribaea var. caribaea
Provedor de dados: Genetics and Molecular Biology
Autores: Dornelas,Marcelo Carnier; Rodriguez,Adriana Pinheiro Martinelli.
In angiosperms, flower formation is controlled by meristem identity genes, one of which, FLORICAULA (FLO)/LEAFY (LFY), plays a central role. It is not known if the formation of reproductive organs of pre-angiosperm species is similarly regulated. Here, we report the cloning of a conifer (Pinus caribaea var. caribaea) FLO/LFY homolog, named PcLFY. This gene has a large C-terminal region of high similarity to angiosperm FLO/LFY orthologs and shorter regions of local similarity. In contrast to angiosperms, conifers have two divergent genes resembling LFY. Gymnosperm FLO/LFY proteins constitute a separate clade, that can be divided into two divergent groups. Phylogenetic analysis of deduced protein sequences has shown that PcLFY belongs to the LFY-like clade....

Provedor de dados: Horticultura Brasileira
Autores: Cardoso,Jean C; Ono,Elizabeth O; Rodrigues,João D.
The flower industry represents about one billion dollars in Brazil and the development of techniques aimed at flowering control is required. This study evaluated the influence of gibberellic acid (GA3) on the vegetative and reproductive development of young plants of Phalaenopsis FSNT 'Dai-Itigo' hybrid pink color. The application of GA3 was made by foliar sprays at concentrations of 0, 125, 250, 500 and 1,000 mg L -1. The length of leaves increased significantly when using GA3 at low concentrations, but leaf width decreased. The application of GA3 at 125 mg L -1 showed the best results for the promotion of flowering and flower quality of this orchid hybrid. In this treatment, about 50% of plants treated with GA3 flowered about 6-12 months before the...

Autores: Zandonadi,Alessandra S; Maia,Ciro; Barbosa,José Geraldo; Finger,Fernando Luiz; Grossi,José Antônio S.
ABSTRACT Chrysanthemum is one of the most widely marketed cut flower in the world. For this flower cultivation, long days to induce vegetative growth are required, until the plant reaches the necessary size for commercial flowering. The aim of this study was to evaluate the influence of the number of long days on the production of floral stems of five cut chrysanthemum cultivars. The experiment was evaluated in a randomized block design with split plots, with two factors and three replicates. Considering the number of long days (21, 28, 35, 42 and 49) the plots, and sub-plots the cut chrysanthemum cultivars (Calábria, Dragon, Sheena, Apricot Repin and Rebasco). We noticed significant differences for most of morphological traits for number of long days, and...

Green ear yield and grain yield of maize after harvest of the first ear as baby corn
Provedor de dados: Horticultura Brasileira
Autores: Silva,Paulo Sérgio L e; Silva,Paulo Igor B e; Sousa,Ana Karenina F de; Gurgel,Kamila M; Pereira Filho,Israel A.
Baby corn (BC) consists of the corn ear harvested two or three days after silk emergence. BC is a profitable crop, making possible a diversification of production, aggregation of value and increased income. Removing the first female inflorescence induces corn to produce others, making possible to produce several BC ears or, alternatively, BC (by harvesting the first ear) and green ears or grain. The objective of this work was to evaluate green ear yield and grain yield, after harvesting the first ear as BC. Corn cultivar AG 1051 was submitted to the following treatments, in a random block design with ten replicates (52 plants per plot): BC harvesting; green ear harvesting (grain moisture content between 60 and 70%); mature ear harvesting; BC harvesting and...

Os conhecimentos sobre estruturas florais e épocas de floração, tipos de frutos e épocas de maturação contribuem sobremaneira para o sucesso de um sistema de produção de sementes. Os mapas de floração e frutificação são necessários para a programação de colheita de sementes. 0 desconhecimento da época de frutificação causa perda total da colheita de sementes de certas espécies. Desconhecendo-se a época de colheita destes frutos perde-se toda a produção do ano, porque estes se abrem nas árvores e as sementes são dispersadas pelo vento.

Initial performance of own-rooted and budded 'Sunraycer' nectarine plants
Provedor de dados: Pesquisa Agropecuária Brasileira
Autores: Jimenes,Isabela Maria; Mayer,Newton Alex; Dias,Carlos Tadeu dos Santos; Silva,Simone Rodrigues da.
Abstract: The objective of this work was to evaluate the performance in the field of 'Sunraycer' nectarine plants when own rooted and budded onto 13 clonal rootstocks. For this, flowering, flushing, fruit maturity, vigor, and production were assessed. The time span between the end of flowering and the harvest period was shorter for 'Sunraycer' budded onto the 'G x N.9', 'Santa Rosa', and 'Ishtara' rootstocks. 'Flordaguard' and 'Ishtara' induced the largest and smallest canopy sizes, respectively. 'Flordaguard' resulted in the greatest production, and 'Cadaman', in the lowest. Own-rooted 'Sunraycer' plants produce heavier fruits and can be an alternative to growers.

Autores: Bomfim,Isac Gabriel Abrahão; Bezerra,Antônio Diego de Melo; Nunes,Alexandre Campos; Freitas,Breno Magalhães; Aragão,Fernando Antonio Souza de.
The objective of this work was to evaluate the floral biology and pollination requirements of seeded and seedless mini watermelon varieties, and to determine the best varieties to cultivate under protected environment. Three seedless (HA-5106, HA-5158, and HA-5161) and two seeded (Minipol and Polimore) genotypes were tested. Flowers were monitored from the pre-anthesis stage to senescence, and fruit quality was also evaluated. The evaluated treatments were hand-geitonogamous pollination (MG), cross-pollination with pollen from the Polimore variety (MCP), cross-pollination with pollen from the Minipol variety (MCM), and restricted pollination. All varieties had monoecious plants with diclinous flowers, and the stigmas remained receptive throughout anthesis....

Autores: Souza,Rafaela R. de; Beckmann-Cavalcante,Márkilla Z.; Silva,Alcilane A.; Silva,Everaldo M. da; Brito,Leonardo P. da S.; Silva,Adriano O.
ABSTRACT Light is one of the factors that most affect crop growth and yield. However, the control of light intensity is difficult, because, under certain environmental conditions, light energy may exceed or limit the capacity of plants to use it. In this sense, the productive behavior of plant species in shaded environments needs to be known. This study aimed to evaluate the effect of different shaded environments with black shade nets [0 (full sun), 35 and 50%, and overlap 35 + 50% shading nets] on flowering, yield and quality of inflorescences of Heliconia psittacorum (cv. 'Golden Torch'). The shaded environments caused a reduction in the number of days for inflorescence emergence and in the cycle of H. psittacorum (cv. 'Golden Torch'). The yield and...

Reproductive phenological pattern of Calotropis procera (Apocynaceae), an invasive species in Brazil: annual in native areas; continuous in invaded areas of caatinga
Provedor de dados: Acta Botanica Brasilica
Autores: Sobrinho,Mellissa Sousa; Tabatinga,George Machado; Machado,Isabel Cristina; Lopes,Ariadna Valentina.
In this study, we evaluated the phenological patterns (vegetative and reproductive) of Calotropis procera (Apocynaceae-Asclepiadoideae) in Brazil, comparing its phenology in an area where it is invasive with that observed in areas to which it is native. Phenological observations were carried out over a 24-month period at sites in and around areas of caatinga (shrublands). We estimated the relative frequency of each phenophase, and we documented a dramatic difference between phenophases in terms of the pattern of reproductive phenology . The pattern of continuous flowering and fruiting observed in the invaded area strongly diverges from the 2- to 6-month flowering and fruiting period of the annual pattern. The continuous pattern of reproduction seems to...

Provedor de dados: Acta Botanica Brasilica
Autores: Liuth,Heitor Scarpati; Talora,Daniela Custódio; Amorim,André Márcio.
In tropical forests with low seasonality, climatic variables generally exert a weak influence on the phenology of species. The seasonality of phenophases in closely related taxa can be controlled by phylogenetic constraints in such environments. In this study, our aim was to describe the phenology of Rubiaceae in the understory of the Atlantic Forest in the southern part of Bahia, Brazil, as well as to evaluate the seasonality and phenological synchrony of this family. For two years, we observed 90 individuals belonging to 13 species, in an area of 0.2 ha. Leaf flushing and leaf fall did not demonstrate any seasonality, were continuous for most species and correlated with few of the climatic variables. Flowering was seasonal and correlated positively with...

Autores: Lacerda,Dinnie Michelle Assunção; Rossatto,Davi Rodrigo; Ribeiro-Novaes,Éville Karina Maciel Delgado; Almeida Jr.,Eduardo Bezerra de.
ABSTRACT Evergreen (EG) and deciduous (DEC) species exhibit distinct strategies to overcome dry periods and achieve adequate water status for reproduction and growth. Such particularities may result in distinct reproductive strategies between these groups. Thus, we evaluated the phenology of EG and DEC groups, comparing and differentiating their reproductive phenophases in an area of Brazilian savanna (cerrado sensu stricto), located in Mirador State Park, Maranhão State, by associating these patterns with leaf fall and flushing. Leaf fall, leaf flushing, flowering and fruiting data were monitored between April 2014 and March 2016 for 12 EG and 13 DEC species. To assess differences in flowering and fruiting patterns between EG and DEC, we compared...

Dynamics of miR156 and miR172 involved in the flowering of Jatropha curcas L.
Provedor de dados: Acta Botanica Brasilica
Autores: Sánchez-Gutiérrez,Adriana; Ovando-Medina,Isidro; Adriano-Anaya,Lourdes; Vázquez-Ovando,Alfredo; Salvador-Figueroa,Miguel.
ABSTRACT Jatropha curcas is a plant that accumulates high-quality oil in its seeds, which is capable of being transformed into liquid biofuel. However, several aspects of its flowering are still unknown, which is a key step in the production of fruits, seeds, and oil. Flowering is a complex process that is regulated by various factors at the molecular level, including microRNAs (miRNAs). There is evidence suggesting that the miRNAs of the miR156 and miR172 families play a key role in the flowering transition of plants. For this reason, the dynamics of miR156 and miR172 were studied during a production cycle of J. curcas. Our results reveal that J. curcas has a mechanism for the expression of these miRNAs that differs from that reported for the vast...

The effect of applications of low concentrations of salicylic acid (SA) on the number of flowers and the date of flower initiation in Petunia (Petunia híbrida) in reported in this paper. Concentrations of 1 μM to lpM of SA were spread on three occasions to the shoot of plantlets cultivated in greenhouse conditions. Analysis of the results showed that all the concentrations of SA tested increased the number of open flowers per plant. Concentrations as low as lpM or 0.lnM induced positive riesponses by 33 % and 37 %, as compared with that of the control. The highest concentration of 1 μM increased not only the number of flowers by 72 % but also induced early flowering by six days.

Autores: DOMICIANO,GISELE P.; ALVES,ALEXANDRE A.; LAVIOLA,BRUNO G.; ALBRECHT,JULIO C.
Phenological studies can provide information that enables the understanding of the dynamics of plants and how these dynamics are related to the biotic and abiotic environment. In order to study the phenological phases of Jatropha during two agricultural years, agronomic and climatic variables, such as temperature and rainfall, were evaluated. Data for each variable in each year and each genotype were subjected to analysis of variance (ANOVA) and the differences were tested at 5% probability by F test. In addition, the correlation of growth behavior and reproductive development of two Jatropha accessions (CNPAE-102 and CNPAE-169) as a function of time elapsed after the start of the phenological cycle with climatic variables were analyzed through Pearson's...

Provedor de dados: Biota Neotropica
Autores: Pessoa,Michaele de Souza; Vleeschouwer,Kristel Myriam De; Talora,Daniela Custódio; Rocha,Larissa; Amorim,André Márcio Araújo.
Although Miconia mirabilis is a very common species in disturbed forest areas and is known for providing food resources for the local fauna, little is known about its reproductive phenology and other ecological aspects. The present study compares intra- and inter-annual patterns in the reproductive phenophases of that species in three distinct physiognomies of Atlantic Forest in Southeastern Bahia based on semi-quantitative observations conducted over a period of three years. We searched for possiblerelationships with climatic variables, differences among sites and synchrony. Both the flowering and fruiting strategies of M. mirabilis were classified as annual extended in all three study sites. We found no significant differences among years. Despite low...

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Arba,Mohamed; Falisse,André; Choukr-Allah,Redouane; Sindic,Marianne.
ABSTRACT The cactus is a succulent plant resistant to droughts. According to the recently reviewed classification, cacti belong to the family of Opuntiaceae Desv. (synon. Cactaceae Juss.) with Opuntia Mill. as the typical genus. This genus is economically the most important in the family, as it includes a group of cactus pear plants which play an important role in the agricultural systems of arid and semi-arid regions. Flowering of the cactus pear fruit is an important determinant of the fruit harvesting period. The goal of this paper is to present the physiology of the cactus pear and to explain in detail the biology of its flowering and fruiting processes. This study is also enriched by our observations on the flowering and fruiting of three varieties of...

Physico-chemical and harvest time alterations in pineapple fruits ‘Smooth Cayenne’ caused by paclobutrazol
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Antunes,Andréa Maria; Ono,Elizabeth Orika; Sampaio,Aloísio Costa; Rodrigues,João Domingos.
The aim of this work was to assess the effect of an inhibitor acting in the floral differentiation on the physico-chemical characteristics of pineapple fruits and on the effect in the harvest time. Paclobutrazol was used at concentrations of 100, 150, and 200 mg L-1, applied 2, 3 or 4 times in ‘Smooth Cayenne’ pineapple plants. The treatment did not influence the chemical characteristics of the fruits, and even having some physical alterations, they were within the quality standard for the commercialization. The harvest time was amplified in all the treatments comparing to the control. However, 150 mg L-1 applied twice promoted the best result when analyzing together the harvest time and the fruit fresh matter.

EgLFY, the Eucalyptus grandis homolog of the Arabidopsis gene LEAFY is expressed in reproductive and vegetative tissues
Provedor de dados: Brazilian Journal of Plant Physiology
Autores: Dornelas,Marcelo Carnier; Amaral,Weber A. Neves do; Rodriguez,Adriana Pinheiro Martinelli.
The EgLFY gene cloned from Eucalyptus grandis has sequence homology to the floral meristem identity gene LEAFY (LFY) from Arabidopsis and FLORICAULA (FLO) from Antirrhinum. EgLFY is preferentially expressed in the developing eucalypt floral organs in a pattern similar to that described previously for the Arabidopsis LFY. In situ hybridization experiments have shown that EgLFY is strongly expressed in the early floral meristem and then successively in the primordia of sepals, petals, stamens and carpels. It is also expressed in the leaf primordia of adult trees. The expression of the EgLFY coding region under control of the Arabidopsis LFY promoter could complement strong lfy mutations in transgenic Arabidopsis plants. These data suggest that EgLFY plays a...

Ecophysiology of the cacao tree
Provedor de dados: Brazilian Journal of Plant Physiology
Autores: Almeida,Alex-Alan F. de; Valle,Raúl R.
Cacao, one of the world's most important perennial crops, is almost exclusively explored for chocolate manufacturing. Most cacao varieties belong to three groups: Criollo, Forastero and Trinitario that vary according to morphology, genetic and geographical origins. It is cropped under the shade of forest trees or as a monocrop without shade. Seedlings initially show an orthotropic growth with leaf emission relatively independent of climate. The maturity phase begins with the emission of plagiotropic branches that form the tree crown. At this stage environmental factors exert a large influence on plant development. Growth and development of cacao are highly dependent on temperature, which mainly affects vegetative growth, flowering and fruit development....

Citrus is the main fruit tree crop in the world and therefore has a tremendous economical, social and cultural impact in our society. In recent years, our knowledge on plant reproductive biology has increased considerably mostly because of the work developed in model plants. However, the information generated in these species cannot always be applied to citrus, predominantly because citrus is a perennial tree crop that exhibits a very peculiar and unusual reproductive biology. Regulation of fruit growth and development in citrus is an intricate phenomenon depending upon many internal and external factors that may operate both sequentially and simultaneously. The elements and mechanisms whereby endogenous and environmental stimuli affect fruit growth are...

Provedor de dados: Ciencia e Investigación Agraria, Revista Latinoamericana en Ciencias de la Agricultura
Autores: Beyá-Marshall,Víctor; Fichet,Thomas.
The aim of this study was to characterize the phenological, vegetative and reproductive behavior variables of ‘Frantoio’ olive trees in an "off’ year (with a low crop load) and an "on" year (with a high crop load). To do this, during the 2011-2012 and 2012-2013 seasons, "off" and "on", respectively, phenological variables, plant growth (shoots and roots) and reproductive growth (type of flower, fruit set and growth), were monitored biweekly. In addition, the yield per tree was assessed, and the crop load was estimated. The main results showed that crop load strongly influenced these variables. The distribution and intensity of vegetative growth, both in the roots and aboveground, decreased more and had lower intensity in the high fruiting season, with a...

Decreased time from seed to flowering corm size in Zephyra elegansvia in vitro cultivation
Provedor de dados: Ciencia e Investigación Agraria, Revista Latinoamericana en Ciencias de la Agricultura
Autores: Vidal,Alexis K; Han,Dong-Sheng; Nakano,Masaru; Niimi,Yoshiji.
Experiments were performed to establish a method to reduce the time from seed to flowering in Zephyra elegans. Seedlings took at least four years to produce a flowering corm. Although germination was highest in a water-agar medium, plant necrosis occurred when plants were later transferred; therefore, MS (Murashige and Skoog) medium was selected as the medium for germination. An increase in the light intensity to 9500 lux and in the pH to 6.7, significantly increased the germination rate. Eight weeks after seed germination, seedlings were transferred to MS media with sucrose concentrations of 45, 60, 75, 90 or 105 g L-1 and a pH 5.7 or 6.7, with the aim of achieving the greatest corm weight gain. After 16 weeks, the best weight gain was obtained in the MS...

A temperature response function for development of the chrysanthemum (Chrysanthemum x morifolium Ramat.)
Provedor de dados: Ciência Rural
Autores: Streck,Nereu Augusto.
Developmental models can help growers to decide management practices, and to predict flowering and harvest time. Currently, a double exponential function is proposed as a generalized temperature response function for chrysanthemum. This function is not the most appropriate because its parameters lack biological meaning. The objective of this study was to develop a nonlinear temperature response function of chrysanthemum development that has parameters with biological meaning. The proposed function is a beta function with three parameters, the cardinal temperatures (minimum, optimum, and maximum temperatures for development), which were defined as 0, 22, and 35ºC. Published data of temperature response of development of three cultivars, which are...

Autores: Lima,Juliana Domingues; Ansante,Nathalia Felipe; Nomura,Edson Shigueaki; Fuzitani,Eduardo Jun; Silva,Silvia Helena Modenese-Gorla da.
Gibberellic acid (GA3) induces flowering of plants of various genera of the Araceae family. Therefore, it was evaluated the effect of GA3 on the growth and yield of Anthurium andraeanum cv. 'Apalai'. For this purpose, micropropagated seedlings were planted in nursery beds under 70% shade. The experimental design was completely randomized in subdivided plots with eight replications. The growth regulation effect was assessed in each plot and the time to flowering after the start of the treatments was assessed in each subplot. The GA3 concentrations were 0, 150, 300, 450 and 600mg L-1, applied every 60 days by spraying on the leaves. The applications and evaluations started after the production of marketable floral stems. Every month the number of leaves was...

ABSTRACT: The objective of this study was to evaluate the effects of different doses of uniconazole (UCZ) on 'Palmer' mango vegetative and reproductive response and on fruit physical, chemical, and productive characteristics during the off-season in northern Minas Gerais, Brazil. The experiment followed a randomized block design. UCZ was tested at the following doses applied to leaves and expressed in g of UCZ active ingredient (a.i.) per tree: 0.0, 1.0, and 1.0+1.0 (2.0) after 30 days; 1.0+1.0+1.0 (3.0) subdivided into 30-day intervals; and 1.0+1.0+2.0 (4.0) subdivided into 30-day intervals. All of the UCZ treatments reduced branch elongation in the 'Palmer' mango trees, leading to a mean reduction of 81.6% compared to the control. However, the UCZ...

Autores: Gurgel,Fábio de Lima; Laviola,Bruno Galvêas; Silva,Daniel Medeiros da; Kobayashi,Adilson Kenji; Rosado,Tatiana Barbosa.
Phenological studies on three morphologically distinct accessions of physic nut (Jatropha curcas L.) were conducted in the Brazilian Savannah biome. Plant growth rate, flowering, fruit formation and development were measured in order to establish appropriate management practices for increasing productivity. The accessions CNPAE-102 (toxic and susceptible to powdery mildew), CNPAE-169 (non-toxic and susceptible to powdery mildew) and CNPAE-259 (toxic and resistant to powdery mildew) were studied. Accessions with undetectable levels of phorbol ester in the grains were considered as non-toxic. The agronomic variables (plant height, number of inflorescences, number of green and ripe fruits per plant) from each accession were measured biweekly during one year...
