摘要:: 以东北红豆杉种子为试材，研究了不同浓度赤霉素（GA₃）及不同温度层积处理对东北红豆杉种子后熟过程中种子贮藏物质的影响，以探讨打破东北红豆杉种子休眠的有效途径。结果表明：结合GA₃处理进行不同温度层积处理，与对照相比，东北红豆杉种子可溶性糖含量增加、脂肪含量下降、可溶性蛋白质含量下降，GA₃200 mg/L处理结合变温层积效果最好，说明赤霉素处理结合变温层积能有效促进东北红豆杉种子后熟过程中贮藏物质转化，为胚发育提供养分和能量。

Abstract:: aking Taxus cuspidata Sieb.et Zucc.seeds as test material,the effects of different concentrations of GA₃ with different temperature stratifications on the storage substance changes were studied,in order to explore effective ways to break seed dormancy of Taxus cuspidata Sieb.et Zucc.The results showed that combined the GA₃ treatment and the different temperature stratification,compared to CK,the soluble sugar content of Taxus cuspidata ?Sieb. et Zucc. was increased,the fat content was decreased,the soluble protein content was decreased,effect of GA₃200 mg/L treatment combined with the different temperature stratification was the best.It showed that Gibberellin treatment combination of the different temperature stratification can effectively promote the storage substance transformation of Taxus cuspidata Sieb.et Zucc.after maturity,providing nutrients and energy for embryo development.
