Seed Germination Characteristics of Endangered Medicinal Ferula tadshikorum
摘要
Abstract
Ferula tadshikorum is an important rare medicinal plant resource.Exploring the dormancy characteristics of its seeds and finding ways to break dormancy are the scientific basis and premise for its ex situ conservation and artificial cultivation.Taking its wild seeds as the research material,the basic biological characteristics of fruit and seed,seed water absorption,seed structure and seed germination inhibitors were studied by indoor control experiment method,and the effects of germination temperature,stratification treatment and interaction of different concentrations of GA3 on germination rate,germination potential and germination index were analyzed.The results showed that,the seed coat did not hinder seed water absorption and the embryo morphology developed completely when the fruit was mature.The seed powder leaching solution had a significant inhibitory effect on the germination of Chinese cabbage seeds.Using 15 ℃/5 ℃ germination temperature,without GA3 soaking,low temperature stratification for 45 days can significantly improve the germination rate of F.tadshikorum seeds.The seed dormancy type of F.tadshikorum was physiological dormancy,which was caused by the combination of germination inhibitors in seeds and physiological after-ripening of embryo.Seed stratification for 45 days before sowing and then germination at 15 ℃/5 ℃ can effectively relieve seed dormancy and promote seed germination.关键词
