夏枯草种子萌发及其幼苗生长对干旱胁迫的响应
Seed Germination and Seedling Growth of Prunella vulgaris L.in Response to Drought Stress
摘要
Abstract
[Objective] To discuss the effects of drought stress on germination of Prunella vulgaris L.seeds and seedling growth.[Method] By using different concentrations of polyethylene glycol(PEG-6000), seed germination rate (Gr), germination index (GI) , germination potential (Gp)and seedling root length, plant height, fresh weight and dry weight indicators were determined.[Result] The results indicated that different PEG concentrations had different effects on the germination of P.vulgaris seeds and seedlings growth with the increase of drought intensity.[Conclusion] Low concentrations(2.5%-5.0%) of PEG have the little effects on P.vulgaris seeds, while high concentrations(10.0%-15.0%) have a large effects, 10.0% concentration promotes the growth of underground part, for the overground part, low concentration suppression is not obvious, high concentrations of various indexes significantly inhibit.关键词
