不同浓度GA_3对东北延胡索种子萌发的影响
|
摘要
通过不同浓度赤霉素处理对东北延胡索种子萌发的试验研究,筛选出适宜种子萌发的赤霉素浓度,以期为东北延胡索种质资源的保存与育种提供科学依据与理论支持。将不同浓度赤霉素处理的东北延胡索种子分别放在10℃、15℃、20℃、25℃恒温条件下进行种子萌发,测定其发芽率、发芽势、萌发时间等生理指标。结果,赤霉素200 mg/L、温度15℃条件下最适合种子萌发。
The paper discusses the effects of different temperature and different concentrations of gibberellin on seed germination of Corydalis ambigua Cham. et Schlecht.To provide scientific basis and theoretical support for the preservation and breeding of germplasm resources.After effect of GA_3 treatments with different concentrations of the C.ambigua Cham. et Schlecht. seeds were cultured in 10 ℃,15 ℃,20 ℃,25 ℃ constant temperature light incubator to determine the physiological indexes.The seeds were favorable for seed germination at15 ℃,200 mg/L.Gibberellin breaks seed dormancy,which favors seed germination.
