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.
