Study on Variation of Endogenous Hormones Contents in Aconitum flavum Hand.-Mazz.Seeds during the Process of Dormancy and Germination
摘要
Abstract
[Objective] To study variation of endogenous hormones contents in Aconitum flavum Hand. - Mazz seeds during the process of dormancy and germination. [ Method] Contents of GA3 ,AA, ABA and Z in Aconitum flavum Hand. - Mazz seeds that were new, old and processed under stratification were determined and analyzed by HPLC respectively. Besides,germination rate of seeds were investigated. [ Result] Contents of ABA and GA3 in seeds respectively declined and increased during the process of stratification; different stratification treatments had certain effects on seeds germination with the extending of time. [Conclusion]GA3 was critical for breaking dormancy and promoting germination of seeds; ABA was the important factor in inhibiting germination; IAA played an important role in promoting seeds germination; there was no obvious correlation between Z content and seeds germination of Aconitum flavum Hand. - Mazz.关键词
