Germination responses of Peucedanum ostruthium (Apiaceae) to genotype, light, temperature and gibberellic acid

Towards an Understanding of Factors Controlling Seed Bank Composition and Longevity in the Alpine Environment

“…Seeds of Silene elisabethae, showed increased germination percentage with increase in cold-wet stratification duration, but germination was tightly controlled by light (Mondoni et al, 2009). Novak et al (2011) also noted seeds of Peucedanum ostruthium are better germinated at 26˚C only in light. These studies clearly depict light plays a pivotal role in controlling the timing of seed germination form seed banks.…”

“…Typically, 25 to 35˚C is the most favorable temperature eliciting autumn germination in the proportion of non-dormant/conditionally dormant seeds (Clebsch and Billings, 1976;Kibe and Masuzawa, 1994;Nishitani and Masuzawa, 1996;Körner, 1999;Novak et al, 2011). Autumn germination is facilitated further if the temperature fluctuates between 20 and 30˚C (Sayers and Ward, 1966;McDonough, 1970).…”
