A STUDY ON SEED GERMINATION OF AVENA LUDOVICIANA AND THE EFFECTIVE FACTORS IN SEED DORMANCY BREAKING
Wild oat has two seeds in a spikelet that they have different physiological behavior in regard of seed germiantion. The upper seed of spikelet is smaller and has deeper dormancy than the lower seed. The range of temperature for germination is 5˚C to 25 ˚C and optimal temperature is 15˚C. Both kinds of seeds showed the more germination rate in low temperatures so that 5 and 10˚C are better...
متن کاملSeed dormancy-breaking and germination requirements of
Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...
متن کاملThe Effect of Flowering Time on Seed Dormancy Breaking of Almond
Seed’s dormancy is considered as one of the effective factors in seeds germination and consequently in the growth of seeds of many plant species. Shortening the dormancy period and enhancing the germination percentage in fruit types could be a valuable strategy for the seed researchers and plant nurseries. In this research the seeds of mature fruits of different almond cultivars including late-...

متن کاملPlant Development: Multiple Strategies for Breaking Seed Dormancy
Plant seeds will not germinate when in a dormant state. What then are the factors controlling dormancy? A recent study has uncovered two basic-helix-loop-helix proteins which repress germination and are critical for maintaining dormancy. The combined action of light and cold synergistically alleviates activity of these repressors thus stimulating germination.
