Provedor de dados: 32
Autores: Muñoz Gutiérrez, Liliana.
Con el propósito de establecer un programa de producción de semilla en Pseudotsuga menziesii y disminuir la presión en la cosecha de semilla en poblaciones naturales de la especie, se evaluó el efecto del ácido giberélico (AG4/7) y del anillado en el tronco en la formación de estructuras reproductivas y en el crecimiento del brote en dos ensayos de campo y uno en macetas con árboles juveniles. Se utilizaron cuatro dosis de AG4/7 (0, 1.27, 2.55 y 5.10 mg cm-2) aplicadas por inyección en el tronco; durante el periodo de crecimiento se midió la longitud del brote y un año después se evaluó el porcentaje de árboles con respuesta, y el número y posición de las estructuras reproductivas. La proporción de árboles con estróbilos femeninos fue de 37.5 % en el...

Floral pipe: length in Petunia x hybrida heredability, number of genes and the interaction of the date with the character
Provedor de dados: 46
Autores: Fatta,N.; Vazquez,M.; García,N.; Mascarini,A.; Grigioni,G.
Petunia x hybrida, a floral summer of a economical importance in Buenos Aires, is nowadays produced with imported seed. The research presented is focused on the study of the feasibility to obtain locally competitive seed. The length of the floral pipe is a relevant character so the assay was designed in order to estimate the heredability, the number of genes intervener and the interactions with the date. The assay began with a F1 purchased from United States. In 2003, the F1 and F2 were sowed,739 individuals of F2 were placed in pots in three dates: 12/6, 26/6 and 8/7/2003 that were considered as blocks I, II and III respectively in a completely randomized design. It was assumed that the homocigotas would be situated in the tales of the F2 distribution,...

Autores: Muhammad,   Lutta; Njoroge,   Kiarie; Bett,   Charles; Mwangi,   Wilfred; Verkuijl,   Hugo; De Groote,   Hugo.
The development and promotion of improved crop varieties as well as efficient seed production, distribution, and marketing systems have contributed significantly to increased agricultural production and food security in Kenya. However, these impacts have not been replicated in the semi-arid midlands due to climatic, soil, and institutional factors. Following the liberalization of agriculture in the late 1980s, there has been greater participation of the private sector, non-governmental organizations, and voluntary agencies in the area. This study examined the extent to which these developments affected farmers’ access to dryland crops. The study found that the low quantity of seed traded, high cost of production, and high seed supply prices constrained the...

The publication describes outcomes of a study conducted in 2007/08 to analyze the bottlenecks affecting the production and deployment of maize seed in eastern and southern Africa. The objectives of the study were to provide a better understanding of the factors limiting the production and deployment of improved maize seed in Africa, and to contribute to increasing the efficiency of variety release, seed production and seed dissemination for new drought tolerant maize varieties. The study identified a number of institutional bottlenecks affecting the maize seed value chain, in particular in the area of policy, credit availability, seed production, germplasm and marketing. To address these bottlenecks and improve the efficiency of seed production and...

Seed characteristics and dispersal of dimorphic fruit segments of Cakile maritima Scopoli (Brassicaceae) population of southern Brazilian coastal dunes
Provedor de dados: 88
Autores: Cordazzo,César Vieira.
Cakile maritima occurs sporadically along the southern Brazilian coast, where it is restricted to more protected sites at the base of foredunes. Somatic dimorphism in C. maritima is manifested as morphologically distinct upper and lower fruit segments (silicules). The two morphs were tested for differences in size, number of seeds, dispersal ability and natural establishment. In the C. maritima population of southern Brazil, the lower silicule has more seeds than upper silicule, and lower seeds are more likely to abort than the upper ones. Seeds from upper segments were significantly larger than those from lower ones; however, their mass ranges overlap. The mean silicule mass was not significantly different from both segments, but the silicule/seed mass...

Influence of temperate grass seed rotation systems on weed seed soil bank composition
Provedor de dados: 95
Autores: Medeiros,Renato Borges; Steiner,Jeffrey J.
Due to changing cropping practices in perennial grass seed crops in western Oregon, USA, alternative rotation systems are being considered to reduce weed infestations. Information is generally lacking regarding the effects of alternative agronomic operations and herbicide inputs on soil weed seed bank composition during this transition. Six crop rotation systems were imposed in 1992 on a field that had historically produced monoculture perennial ryegrass (Lolium perenne L.) seeds. Each system plot was 20 x 30 m, arranged in a randomized complete block design, replicated four times. Twenty to thirty soil cores were sampled in June 1997 from each plot. The weed species composition of the cores was determined by successive greenhouse grow-out assays. In...

ABSTRACT This study aimed to determine the variability and expression of the components of seed yield in twenty-three apomictic Paspalum plicatulum × Paspalum lepton hybrids and two male parent plants (P. lepton). We used a randomized block design with genotypes individually arranged into ten blocks. The variables were: number of total tillers/plant, number of vegetative tillers/plant, number of reproductive tillers/plant, percentage of reproductive tillers, number of racemes/inflorescence, number of seeds/inflorescence, weight of a thousand seeds, and seed yield. We assessed genetic variability using multivariate procedures: generalized Mahalanobis distance, Tocher's clustering optimization method, and quantification of the relative contribution of the...

ABSTRACT: Stylosanthes capitata Vogel and Stylosanthes macrocephala M.B.Ferreira &amp; Sousa Costa are two forage leguminous species of agronomic importance for animal husbandry in tropical environments. The physical mixture of both species (80 % S. capitata and 20 % S. macrocephala) comprises the commercial cultivar &amp;#8220;Estilosantes Campo Grande”. However, proximity of fields for seed production may contaminate seed lots, compromising seeds quality. The combined use of dominant and co-dominant molecular markers is an appropriate strategy to certificate genetic purity and perform diversity studies of cultivars. In this research, a set of ISSR (Inter-Simple Sequence Repeat polymorphic DNA) and SSR (Simple Sequence Repeat polymorphic DNA) molecular...

การพัฒนาการผลิตเมล็ดพันธุ์ข้าวลูกผสม กขผ1 เชิงพาณิชย์
Provedor de dados: 106
Autores: Pornsuree Kanjana; Wilai Palawisut.
RDH1 is the first hybrid rice variety being released by Rice Department. It is ideal for irrigated areas due to it’s high yield characteristics. Despite the high yield, seed production procedures of hybrid rice are more complicated than the normal ones as hand transplanting is needed. Procedures start from transplanting two sowing dates of male parental line JN43-1-5-5-1-3-1 (R-line) prior to that of the female one, IR79156A (A-line). Furthermore, flag leaf has to be cut off and hand-pollination is needed. The flag leaf cutting leads to the occurrence of dirty panicle disease and therefore the application of fungicide. This increases the cost of production which is unfavorable for the farmers. Thus, transplanting machine is introduced to improve the...

Flower trade-offs derived from nectar investment in female reproduction of two Nicotiana species (Solanaceae)
Provedor de dados: 39
Autores: Galetto,Leonardo; Araujo,Francielle Paulina; Grilli,Gabriel; Amarilla,Leonardo D.; Torres,Carolina; Sazima,Marlies.
ABSTRACT Animal-pollinated flowers may orient resources for competing activities, such as nectar production for attracting flower visitors but then saving nectar (through inhibiting nectar production or by final resorption) for the subsequent maturation of fruits and seeds. Nectar production is continuous in Nicotiana longiflora and N. alata after flower opening, but early nectar removal reduces total secreted nectar. Resource trade-off between nectar investment and seed production were experimentally assessed in manually pollinated flowers experiencing different numbers of repeated nectar removals, while controlling for maternal effects. We expected that flowers with less nectar secretion produce larger seed sets. The results showed that for both species...

Seed production and seed quality of the dune building grass Panicum racemosum Spreng
Provedor de dados: 39
Autores: Cordazzo,Cesar Vieira; Davy,Anthony John.
Seed production, pollination requirement, seed characteristics related to quality and the relationship between number and mass of seeds were examined for Panicum racemosum in three successional populations in southern Brazilian coastal dunes. The seed production was generally low and declined further between the frontal dunes and the backdunes, dropping from 4.05 seeds per panicle in the former to 1.8 seeds in the latter. However fertility (% fertile florets) did not differ among the three habitats. Plants cross-pollinated in a glasshouse showed an increase in seed production to 41.4 seeds compared to no seed production in self-pollinated plants. Caryopses varied in mass from 3.2 to 12.2 mg with a mean of 7.98 mg. A strong negative correlation was found...

Population ecology of Paepalanthus polyanthus: predispersal hazards and seed production
Provedor de dados: 39
Autores: Castellani,Tânia Tarabini; d'Eça-Neves,Fernanda Faraco.
This study aimed at evaluating seed production and predispersal hazards in a sand dune population of P. polyanthus (Eriocaulaceae) in Southern Brazil. Bad development of flowering capitula was caused by the wind and by interference among umbels. A positive correlation between the proportion of atrophied capitula and the number of capitula/umbels also suggested resource limitation. A caterpillar of a Recurvaria Haworth (Lepidoptera: Gelechiidae) species that eats flowers and a boring caterpillar (Lepidoptera not identified) were the main herbivores. Plants reproducing during the flowering peak had a lower probability of being damaged by Recurvaria sp., suggesting an escape from herbivores by flowering synchronism. The proportion of capitula damaged by...

This experiment was carried out to evaluate the effect of the honeybee pollination in the production and quality of soybean seeds (Glycine max L. Merril). Seed production was higher (P=0.0001) in covered areas with honeybee colonies (50.64%) and uncovered areas (57.73%) than in covered areas without honeybee colonies. It could be concluded that honeybees were responsible for 95.5% of the pollination accomplished by insects. The pod number in covered treatment with honeybees was 61.38% higher (P=0.0002) than in the covered treatment without honeybees. The average weight of 100 seeds was larger (P=0.0001) in the area covered without honeybees, and reached 17.8 g. The medium content of crude protein in grains was 36.7% and the average oil content was 20.2%....
