BACKGROUND Seed germination is a complex physiological process during which mobilization of nutrient reserves happens. In different crops, this event might be mediated by different regulatory and metabolic pathways. Proteome profiling has been proved to be an efficient way that can help us to construct these pathways. However, no such studies have been performed in soybean germinating seeds up ...

in order to achieve high quality seeds, producers must be able to estimate the accurate harvest maturity time seeds. the objective of this study was to investigate changes in seed quality during seed development and maturation in the two cultivars native of the sari and gorgan and two cultivars modified of the darab14 and yellowhite. a field experiment was conducted in during 2009 at gorgan uni...

in order to study the effects of on-farm seed priming and sowing date on germination percentage, germination speed, and some growth indices of three soybean cultivars, a field experiment was carried out in three replications using a split plot factorial in a randomized complete block design. main plots were representative of two sowing date (5th and 21th of may), while subplots included combina...

In order to elucidate the effect of sowing date on oilseed rape (Brassica napus L.) yield and yield components, three varieties including Tower, Rafal and Global were sown from November 7 to December 22, 1998-99 in four dates with 15day intervals in Dezful region. A split-plot design based on randomized complete blocks with four replications was used in which levels of sowing dates and cultivar...

Background: Chia (Salvia hispanica L.) is an herbaceous annual plant of the Lamiaceae family. Chia seeds are rich source of omega-3 fatty acids (a-linoleic acid), proteins, soluble and insoluble fibers, vitamins, minerals and natural antioxidants. Objective: Study of growth, development, yield and oil quality of white and black Chia seeds in different planting dates. Methods: In order to st...

in order to determine of the proper sowing date of steckling (rootlet) and harvesting date of seed, an experiment was conducted in ardabil agricultural research station (alarough) in 2004- 05 growing season in split-plot in randomized complete block design arrangement with four replications. four different planting dates viz. 5th march, 20th march, 4th april and 19th april– were allocated to th...

In tropical forests, pioneer tree species regenerate from seeds dispersed directly into canopy gaps and from seeds that persisted in soil seed banks before gap formation. Life-history models have suggested that selection for the long-term persistence of tree seeds in the soil should be weak because persistence potentially reduces population growth rate by extending generation time and because a...
