El modelo sistémico para la fertilización nitrogenada en brócoli (Brassica oleracea itálica).
Provedor de dados: 32
Autores: Cartagena Ayala, Yamil Everaldo.
La aplicación de nitrógeno para la producción de brócoli suele ser ajustada con base en criterios empíricos con el riesgo de llegar a dosis excesivas. En este sentido, una alternativa para precisar la cantidad de nitrógeno que debe agregarse es a través de la evaluación cuantitativa de la demanda nitrogenada del cultivo, el suministro de nitrógeno del suelo y la eficiencia de la fertilización nitrogenada. Se realizaron dos experimentos (octubre de 2012 a enero de 2013 y abril a julio del 2013) en el Campo Experimental Tlapeaxco de la Universidad Autónoma Chapingo, México. Los factores en estudio para el primer experimento fueron: láminas de riego (3 y 6 mm) y dosis de nitrógeno (80, 160, 240 y 320 kg ha-1), y para el segundo experimento las dosis de...

Efecto de la fertilización en la producción de lavanda (Lavandula x intermedia Emeric ex. Loisel. Var Grosso) y actividad biológica de su aceite esencial.
Provedor de dados: 32
Autores: Guerrero Lagunes, Luz Adela.
Se evaluó el efecto de la fertilización en la producción de flor y aceite esencial de lavanda, así como la actividad biológica del aceite esencial e hidrolato contra Pseudomonas spp y mosca blanca (Trialeurodes vaporariorum). En campo se establecieron los tratamientos  con fertilización al suelo y foliar en un diseño experimental completamente al azar con arreglo factorial 2x3 con cuatro repeticiones. El aceite esencial obtenido de las inflorescencias se utilizó para los ensayos in vitro contra Pseudomonas spp y para los ensayos in situ  contra mosca blanca se utilizó hidrolato obtenido de la destilación del follaje, ambos en un diseño experimental completamente al azar con cuatro repeticiones. La fertilización presentó efectos significativos en todas las...

The anthochron as a building block of flower development
Provedor de dados: 86
Autores: Streck,Nereu Augusto; Schwab,Natalia Teixeira.
Abstract: Plant vegetative development has been widely described using the phyllochron concept, but little effort has been made to describe flower development during the reproductive phase. The objective of this work was to present the anthochron, through a review of the literature, as a building block of flower development, mainly during the flower opening phase. The anthochron is the time interval needed for two subsequent flowers to achieve the same developmental stage, with units of time in days or in ºC day per flower. The concept of anthochron fulfills part of the lack of studies on flower development, since it is considered a building block of the flower opening process. The anthochron can be measured from field experiments or estimated by a simple...

Lycaenid caterpillars (Lepidoptera, Lycaenidae) eating flowers of Dalea pennellii var. chilensis (Fabaceae) in the northern Chilean Andes
Provedor de dados: 92
Autores: Vargas,Héctor A.
Lycaenid caterpillars (Lepidoptera, Lycaenidae) eating flowers of Dalea pennellii var. chilensis (Fabaceae) in the northern Chilean Andes. The shrub Dalea pennellii var. chilensis (Fabaceae) is reported for the first time as a host plant for three Neotropical Polyommatini (Lepidoptera, Lycaenidae, Polyommatinae): Hemiargus ramon (Dognin, 1887), Leptotes trigemmatus (Butler, 1881) and Nabokovia faga (Dognin, 1895), based on two collections performed in the western slopes of the northern Chilean Andes in two consecutive summers. The relative abundance was always above 90% for N. faga while it was always less than 5% for H. ramon and L. trigemmatus. Furthermore, N. faga was not found on inflorescences of other native Fabaceae examined in the study site. This...

Synflorescence morphology of species of Typha L. (Typhaceae): anatomical and ontogenetic bases for taxonomic applications
Provedor de dados: 39
Autores: Carvalho,Jordano Dorval Tavares de; Mariath,Jorge Ernesto de Araujo.
ABSTRACT The inflorescence of plants of the genus Typha L. consists of a polytelic system with the fertile region containing staminate flowers in the terminal portion and pistillate flowers in the basal portion. Although some useful morphological information has been provided to characterize species of the genus, various divergent typologies have arisen due to mistaken interpretations that ignore the different degrees of branching in this indeterminate system. The present study aimed to identify structural homologies by comparing the morphology and ontogeny of the synflorescences of Typha domingensis, T. latifolia and their putative hybrid, T. x provincialis, using standard micro-techniques for light and electron microscopy. Analysis revealed that the...

Phytochemical characterization of essential oil from Ocimum selloi
Provedor de dados: 42
Autores: MORAES,LILIA A.S.; FACANALI,ROSELAINE; MARQUES,MARCIA ORTIZ M.; LIN,CHAU MING; MEIRELES,M. ANGELA A.
Ocimum selloi Benth, a native plant of Brazil, has medicinal uses as anti-diarrheic, antispasmodic and anti-inflammatory product. The yield of essential oils of the inflorescences, containing flowers and seeds, was 0.6%, and the yield of leaves, collected in two different seasons, was 0.25% (June 2000) and 0.20% (January 2001), respectively. The essential oils of the inflorescences and leaves presented as major constituents trans-anethol (41.34%, 45.42%, 58.59%) and methyl chavicol (27.10%, 24.14%, 29.96%).

Karyotypic studies and morphological analysis of some reproductive features in five species of Conyza (Astereae: Asteraceae) from Northeastern Argentina
Provedor de dados: 51
Autores: Urdampilleta,Juan D.; Amat,Aníbal G.; Bidau,Claudio J.
The cosmopolitan genus Conyza Less. comprises about 100 species, 22 of which occur in Argentina. Current taxonomic treatments, largely based on exomorphological characters, are insufficient to characterize and circumscribe some of their polymorphic species. Interspecific variations in inflorescences typology and capitula structure, as well as karyotypic aspects, were studied in five species of Conyza that naturally occur in Misiones Province (Argentina): C. blakei (Cabrera) Cabrera, C. bonariensis (L.) Cronquist var. bonariensis, C. glandulitecta Cabrera, C. primulaefolia (Lam.) Cuatrec. &amp;amp; Lourteig, C. sumatrensis (Retz.) E. Walker var. sumatrensis and C. sumatrensis (Retz.) E. Walker var. floribunda (Kunth) J. B. Marshall. Chromosome numbers for...

Applied aspects of pineapple flowering
Provedor de dados: 53
Autores: Cunha,Getúlio Augusto Pinto da.
Flowering is an amazing, integrated and complex process of multifatorial control, which due to its great importance for agriculture has been extensively studied worldwide. Pineapple is one of the main crops on which many research works about this subject have been carried out, and it was the first one to have artificially induced flowering. However, even with all those studies, pineapple flowering is not yet characterized in many aspects. The main point for the comprehension of the physiologic aspects of flowering initiation is the identification of the factors involved in the differentiation of the apical meristem into floral primordium, as well as how these factors exert their action. This work aimed to describe the flowering process of pineapple plants,...
