Seed 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 کاملA 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 کاملTanned or Burned: The Role of Fire in Shaping Physical Seed Dormancy
Plant species with physical seed dormancy are common in mediterranean fire-prone ecosystems. Because fire breaks seed dormancy and enhances the recruitment of many species, this trait might be considered adaptive in fire-prone environments. However, to what extent the temperature thresholds that break physical seed dormancy have been shaped by fire (i.e., for post-fire recruitment) or by summer...
متن کاملEvaluation of different hormonal and temperature treatments on dormancy breaking of Lavender (Lavandula angustifolia) seed
Extended Abstract Introduction: Lavandula angustifolia L. is one of the most important plants belonging to Lamiaceae which has abundant use in traditional and pharmacological medicine. Lavender seed dormancy is one of the problems in producing seedlings which increases seed consumption. In this regard, an experiment was carried out to investigate different treatments for seed dormancy eliminat...
