samples of grass pea seed (lathyrus sativus) were prepared and analyzed for some chemical composition and as well for their anti-nutritional factors. the rumen degradability coefficients and post ruminal digestibility of dry matter and crude protein of unheated vs. oven heated samples were determined, employing in situ and in vitro techniques. results indicated that grass pea seed contained a c...

tion, pest or disease resistance, or reseeding ability (Harris, 1987; Brink et al., 1999). Widdup et al. (1996) found Small-type white clover, Trifolium repens L., plants predominate that only 10 of 98 ecotype collections from throughout in most closely grazed pastures in the southeastern USA. The role of relative seed production in stand persistence of white clover types the eastern USA were l...

The plant growth regulator BM was formulated to stimulate seed production and fruit growth. In this study, it was hypothesized that the addition of BM would increase levels of polyamines for seed induction and have a direct benefit of improving fertilization and seed set in cotton. This benefit may enhance yield under extreme environmental conditions when endogenous polyamines content is reduced.

By analyzing 296 published and unpublished data sets describing annual variation in seed output by 144 species of woody plants, this article addresses the following questions. Do plant species naturally fall into distinct groups corresponding to masting and nonmasting habits? Do plant populations generally exhibit significant bimodality in annual seed output? Are there significant relationships...

For determining the oil content, seed and fruit characteristics of Ethiopian Jatropha provenances, the study was conducted in five regions of Ethiopia namely Southern Nation Nationalities Peoples Regional state, Amhara region, Tigria region, Oromia region and Benishangul Gumuz Regions, where Jatropha is found abundantly. A total of 23 Zones, 36 Weredas and 40 sampling sites were considered from...

The recent development of genetically modified sugarcane, with the aim of commercial production, requires an understanding of the potential risks of increased weediness of sugarcane as a result of spread and persistence of volunteer sugarcane. As sugarcane is propagated vegetatively from pieces of stalk and the seed plays no part in the production cycle, the fate of seed in the environment is y...

BACKGROUND AND AIMS Considerable variation in seed size commonly exists within plants, and is believed to be favoured under natural selection. This study aims to examine the extent to which seed size distribution depends on the presence of competing neighbour plants. METHODS Phaseolus vulgaris plants rooting with or without a conspecific neighbour were grown in soil with high or low nutrient ...

Rapid and uniform seed germination is a crucial prerequisite for crop establishment and high yield levels in crop production. A disclosure of genetic factors contributing to adequate seed vigor would help to further increase yield potential and stability. Here we carried out a genome-wide association study in order to define genomic regions influencing seed germination and early seedling growth...

Biodiesel production from vegetable oil has gained attention as an alternative fuel to minimize the usage of fossil fuels and reduce greenhouse gases pollution. In Malaysia, oils from local fruit seeds of papaya and rambutan are potential feedstock for biodiesel production due to their high lipid contents and easily available. In the present study, papaya and rambutan seed oils were extracted v...
