seed dormancy

seeds Dormancy

[Sedigheh Sadeghi] Seed dormancy is a mechanism that insures the survival of the species. Madder (Rubia tinctorum L.)r\n seeds present low germination due to the high degree of seed dormancy. Different methods to overcome\r\n seed dormancy were compared: mechanical scarification (sanding), chemical scarification (dilution in\r\n concentrated sulfuric acid for 10, 15 or 20 minutes, dilution in hot water at 70°C and 90°C for 5\r\n and10 minutes, soaking of seed in gibberelic acid (0.05% GA ), light (24 hour), pre chilling at 4°C\r\n for 4, 6 or 3 10 week and germination test (control)... , "[M. Arumugam] Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during\r\n seed development and maturation. In order to study the effect of harvest time on the seed quality\r\n and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice\r\n genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour index\r\n as a measure of seed quality. There were significant differences in germination in different\r\n genotypes in all the six environments as well as days after harvest... , "[Paul C. Bethke] Seed dormancy is a common phase of the plant life cycle, and several parts of the seed can\r\n contribute to dormancy. Whole seeds, seeds lacking the testa, embryos, and isolated aleurone layers\r\n of Arabidopsis (Arabidopsis thaliana) were used in experiments designed to identify components of\r\n the Arabidopsis seed that contribute to seed dormancy and to learn more about how dormancy and\r\n germination are regulated in this species. The aleurone layer was found to be the primary\r\n determinant of seed dormancy... , "[Mohammed A. Al-Fredan] Seed dormancy is a means to allow seeds to initiate germination when conditions are normally\r\n favorable for germination and survival of the seedlings. Dormancy can be regulated by the\r\n environment or by the seed itself. The seed dormancy may be due to unfavorable environmental\r\n conditions or sometimes, some seeds may not germinate because of some inhibitory factor of the seed\r\n itself. Dormancy of seed due to inhibitory factors, are either due to hard seed coat (external) or\r\n physical of physiological status of the interior of the seed. Seed dormancy in Doum palm (H... , "[CONCEIÇÃO A. PREVIERO] Seed dormancy is a marked characteristic of forage grasses seeds and the understanding of the\r\n mechanisms of this phenomenon is of great importance concerning seed technology aspects. It is known\r\n that seed dormancy is naturally released as the time passes. The objective of this study was to\r\n investigate the release of Brachiaria brizantha seeds dormancy packed in two types of packages with\r\n different initial seed moisture contents and stored in a open warehouse in Campinas SP, for 10\r\n months...
