Desarrollo de fruto y calidad de semilla de cinco variedades de Physalis ixocarpa Brot. en el Valle del Fuerte, Sinaloa
Provedor de dados: 32
Autores: Rodríguez Burgos, Alejo.
El tomate de cáscara se explota en Sinaloa (México) desde hace 20 años y su importancia se incrementó en la última década. Existe muy poca información sistematizada del manejo y potencial productivo de diferentes variedades. Aquí se estudió el desarrollo de fruto y semilla, y la calidad de esta, en cinco variedades (Querétaro, Rendidora, Mahone, Orizaba, Carriceño) sembradas en dos fechas (FS1: 6 de septiembre y FS2: 16 de octubre de 2008). Las variedades Querétaro y Mahone tuvieron en promedio un fruto más largo (37 y 34 cm), ancho (43 y 40 cm) y pesado (38 y 34 g, respectivamente), lo que llevó a que Querétaro tuviera el rendimiento de fruto (RendF) más alto (53 t ha-1). El mejor desarrollo de cultivo se observó en FS1, debido a que en FS2 se presentó un...

Autores: Olivares Mercado, Perla Xochitl.
En 1993 se reportó por primera vez en México a Candidatus Liberibacter solanacearum, como el agente causal de la pigmentación morada en las hojas, reducción de tamaño de la planta y necrosis interna de los tubérculos de la papa; posteriormente se detectó este bacterium en los cultivos de tomate, chile y berenjena. Sin embargo, la distribución de las plantas sintomáticas en el campo no tenía un patrón definido hasta que en 2009 se observó la totalidad de plantas atípicas de chile jalapeño cv Ixtapa en dos campos de los estados de Nayarit y Jalisco. Las plantas tuvieron una reducción de tamaño en un 30%, hojas con coloración verde pálido y deformación de los frutos en un 100%. Por tal razón la presente investigación tuvo como objetivos identificar el agente...

Autores: Gadotti,Gizele I.; Corrêa,Marciabela F.; Navroski,Renan; Nadal,Ariele P.; Schuch,Luis O. B.
ABSTRACT The aim of this research was to study the linear correlations and spatial distribution between soil attributes and productivity and physiological quality of wheat seeds. Soil samples were collected at georeferenced points in an area of 41 ha with a rectangular grid of 100 × 100 m to determine soil fertility. Grain productivity, number of ears m-2, protein content, and physiological seed quality were assessed. The results were submitted to Pearson's correlation analysis, descriptive statistics, and geostatistics. Phosphorus content presented a high spatial variability, with a coefficient of variation of 97.79%. Protein content, number of ears, and SMP index presented low values of coefficient of variation, indicating their low spatial variability....

Germination and hardseedness of seeds in okra elite lines
Provedor de dados: 75
Autores: Purquerio,Luis Felipe V; Lago,Antonio A do; Passos,Francisco Antonio.
The occurrence of hardseedness and the low percentage of seed germination are major challenges when growing okra. For this reason, five elite lines of okra developed at the Campinas Agronomic Institute (IAC), three with angular pods (lines 8.1, 20.1.2 and 47.1) and two with cylindrical pods (lines 13.1.2 and 20.1.R), were evaluated for seed quality and compared to two commercial seed samples (Horticeres Sementes and Sakata Seed Sudamerica) of cultivar Santa Cruz 47. Seeds were field produced in an experiment set in the Technological Park of the Horticulture Center of IAC, in Campinas, São Paulo State, Brazil, in a randomized block design, with three replications and 20-plant plots. Fruits were harvested 25, 35, 45, 55, 65 and 75 days after anthesis (DAA)....

Abstract: The objective of this work was to evaluate the adaptability and multi-trait stability of wheat (Triticum aestivum) genotypes according to the phenotypic index of seed vigor (PIV). Thirty wheat genotypes were grown in seven environments in the state of Rio Grande do Sul, Brazil, during one crop season. In each environment, a randomized complete block design with three replicates was used. The PIV was elaborated from the following traits: first germination count, germination percentage, accelerated aging, and electrical conductivity. The evaluated phenotypic index makes it possible to define macroenvironments for the production of wheat seeds with high physiological potential and to understand the implications of the genotype x environment...

The objective of this work was to evaluate the width and length incidence in a single seed fraction of oat [Avena sativa (L.)] cv. Cristal. The seeds were selected by a mechanical divider and by hand, and their correspondence to radiographic images in seeds with glumes and their caryopses. The width and length of the seeds with glumes and their caryopses were measured with electronic calliper, and their weight, with precision balance. Radiographic images of seeds with glumes were taken with an X-ray experimental equipment. The analyst selected seeds with glumes by the width and by the length previously determined and so with more weight, than that obtained by hand selection was slightly narrower, larger and lighter. The presence of the glumes masked the...

Delivering Seeds of 'Orphan' Crops: The Case Studies of Potato and Groundnut in India
Provedor de dados: 31
Autores: Pal,   Suresh; Singh,   Harbir; Mathur,   Prasoon.
This paper examines the performance of the Indian seed system in the context of high volume, low value seed, using the case studies of potato and groundnut. In theory, public sector should be able to address seed needs of farmers growing these crops. However, the ability of the public sector is constrained by a number of institutional and technical factors, and farmers largely depend upon traditional sources of seed. The traditional sources meet more than two-thirds of the total seed demand , and the rest is met by the formal seed system, mainly public seed agencies. Most of the farmers buy fresh seed for quality reasons, and only 12-15 percent farmers purchase seed to change variety. In potato, technological innovation provided options to enhance...

Test of exudates color hues for evaluating the physiological potential of coffee (Coffea arabica L.) seeds
Provedor de dados: 95
Autores: Hilst,Paulo Cesar; Dias,Denise Cunha Fernandes dos Santos; Alvarenga,Eveline Mantovani; Souza,Bruna Luiza de.
Coffee seeds have slow and irregular germination, losing fast their viability during storage, and the standard germination test of these seeds requires at least 30 days. Besides, the results may not reflect the actual physiological quality of these seeds. The objective of this work was to develop a fast and practical test for evaluating the viability of coffee seeds, which is based on the interpretation of different color hues of exudates from seeds. Coffee seeds of the cultivar Catuai 44 from six lots were submitted to germination, accelerated aging, and electrical conductivity tests. In the exudates color hue test, coffee seeds without the parchment and the silvery pellicle (four replications of 10 seeds each) were distributed on top of paper towels...

Evaluation of lignin content of soybean seed coat stored in a controlled environment
Provedor de dados: 95
Autores: Krzyzanowski,Francisco Carlos; Franca Neto,José de Barros; Mandarino,Jose Marcos Gontijo; Kaster,Milton.
Breeding soybean for high seed quality is an important approach for developing cultivars for tropical regions, and the lignin content in the seed coat is one of the screening parameters for this trait. Considering that many breeding lines are evaluated in each growing season using the presently recommended method for lignin determination, a long period is required for the evaluation of the whole breeding program. This time limitation may influence lignin content assessment, if lignin is degraded during storage. This research reported was designed to determine whether lignin was degraded in the seed coat of soybean seed cultivars stored for one year in a controlled environment (10°C temperature and 50% air relative humidity). Seeds of 12 selected soybean...

Hot and dry weather conditions during soybean [Glycine max (L.) Merrill] seed maturation can cause forced maturation of the seed, resulting in the production of high levels of green seed, which may be detrimental to seed germination. These stressful conditions were imposed on soybean plants during seed maturation to investigate the production of green seeds and seed quality. Plants of the CD 206 cultivar were grown in a greenhouse until the R5.5 growing stage and then transferred to phytotrons at R6 and R7.2 for stress induction. Plants were subjected to two temperature regimes, high (28ºC to 36ºC) and normal (19ºC to 26ºC), and four soil water availability conditions, control (adequate water supply), 30% gravimetric moisture (GM), 20% GM and no water...

Abstract The moisture degree is one of the most important factors in choosing procedures for obtaining high quality seeds. In most quality control programs, the degree of moisture is determined by laboratory tests, based on the maximum removal of water when the seed is subjected to the application of heat under controlled conditions. The radiographic image is characterized by the generation of images with different levels of gray after the interaction of X-rays with the seed tissues. The objective of this research was to determine the gray scale values of radiographic images of soybean (Glycine max (L.)) seeds with different levels of hydration, aiming to establish relationships with the conventional method of moisture determination. Radiographic images of...

The objective of this work was to evaluate the efficiency of nitrogen fixing inoculum associated with Co + Mo leaf spray on the common bean grain yield and grain nutrients, cv. FT Nobre. Three dosages of the inoculant (0, 200 and 400 g/50 kg seeds), combined with four Co + Mo leaf spray levels (T0=0,0; T1=4.9,49; T2=7.3,73; and T3=9.7,97 g ha-1 of Co and Mo, respectively) were tested. The grain yield with the use of the inoculant (400 g / 5O kg seed-1) associated with the higher level of Co+Mo (T2 and T3) was very similar to the mineral nitrogen condition fertilizer recommended for the bean (70 kg ha-1 of N). With the increased inoculant dosage, an increase of the protein content and of P and Mg in the grain was also observed. The results indicated that...

Avocado seeds present high size variability. Larger seeds, such those of the &amp;#8216;Esther&amp;#8217; variety, are preferred when nurse seeds are used. Even though they are considered recalcitrant seeds, they are stored for propagation. The aim of this study was to evaluate the combined effect of three storage periods and three sizes of &amp;#8216;Esther&amp;#8217; avocado seeds on vigor, in terms of electrolyte leakage, and seedling length and diameter. The experiment was conducted using a completely randomized factorial design. The factors were time in storage (10, 30 and 100 d at 5 °C and 80% relative humidity) and seed size (small, medium and large). Electrolyte leakage was evaluated as a measure of seed vigor, growth and later development of the...

Seed coating is a process in which a thin and uniform polymer layer is deposited on the surface of a seed. The objective of this study was to evaluate the vigor of barley seed coated with a commercial polymer and various combinations of calcium, silicon and fungicide. In addition to a control with only the polymer coating, a total of 17 seed coating treatments were used in a completely randomized factorial design (18 treatments × 4 replicates per treatment). Calcium and silicon were applied at concentrations of 0, 25 or 50 g kg¹ of seed, and 0 or 3.0 mL of fungicide was applied. The means were compared using a Duncan test (P&amp;#8804;0.05). The results showed that a coating of polymer, fungicide, calcium and silicon did not affect the physiological...

Autores: Agostinetto,Dirceu; Vargas,Andrés Antonio Monge; Ruchel,Queli; Silva,Jéssica Dias Gomes da; Vargas,Leandro.
ABSTRACT:  In Brazil, horseweed is one of the most important weeds because of the resistance to herbicides and high competitive for the crops. A large of losses were reported in major crops such as soybeans, wheat and corn, where the use a no-tillage system and the herbicide resistance promote better establishment. A correct understanding of the way temperature influences germination enables the prediction of the regions with the highest potential for colonization by this weed and thus facilitates its control. The objective of this study; therefore, was to discern the ways temperature affected the germination, viability and longevity of horseweed seeds. Testing was done at 10, 20 and 30°C, while evaluation occurred on days 0, 15, 30, 45 and 60. Seeds were...

ABSTRACT: This study aimed to evaluate aspects of reproductive phenology, yield components and seed quality of the B4 genotype of  Brachiaria brizantha in function of nitrogen doses applied at pre-flowering. The experiment was carried out at Embrapa Beef Cattle, in a randomized block design, with seeding density of 2.59kg SPV ha-1 in the first year, in free growth plants. Urea was applied at pre-flowering at doses of 0, 25, 50, 75, 100, 125 and 150kg ha-1. The reproductive cycle of the plant lasts 225 days, with late flowering. N doses influenced the following characteristics: number of fully expanded inflorescences, percentage of dry matter, dry biomass, number of spikelets per raceme, seed yield, weight of a thousand seeds, germination, germination speed...

Autores: Baroni,Danilo Força; Vieira,Henrique Duarte.
ABSTRACT Fertilization is not a common management practice at pasture establishment in Brazil. Seed coating technology can be a useful approach to ensure the availability of nutrients to plants during the early stages of development. Thus, the objective of this work was to investigate the incorporation of liquid fertilizer in seeds of Stylosanthes and to evaluate the effect of this technology on seed quality. Mastermins® fertilizer was applied to the last layer of the binder material coating on the seed and Polyseed 76F polymer adhesive was thereafter applied onto the fertilizer. Physiological and biometric analyses of the seeds were carried out. Six fertilizer doses (0, 10, 20, 30, 40, and 50 mL.100 g seeds-1) were tested, with and without adhesive. The...

Autores: Lima,Lidiane Kely de; Ramalho,Magno Antonio Patto; Abreu,Ângela de Fátima Barbosa.
The occurrence of precipitation / rain in harvest bean causes damage to the product and reduces the yield. The main alternative to mitigate this problem is to obtain cultivars presenting low germination of beans in the pods under conditions of high moisture. The purpose of this study was to verify if there is genetic variability among the common bean inbred lines that are in the phase of recommendation for the South of Minas Gerais, Brazil in regard to tolerance to moisture after harvest, and identify traits that may be routinely used in selection of tolerant lines to these conditions. Ninety-five lines in the phase of recommendation by the Genetic Breeding Program from UFLA were used. After harvest, a sample of plants from each plot was removed for...
