W. F. Wight as an experiment material, the effects of different concentrations of GA3 (Gibberellin A3), SA (Salicylic acid) and NAA (1-Naphthalene acetic acid) and stratification on the germination rate of seeds were studied firstly, and then the effects of GA3 and NAA on seedling growth were analyzed. The results showed that the germination rate could be improved by 0.075 g/L SA and stratification markedly. It was indicated by the experiment that the growth of the main root and main stem could be promoted by 0.050 g/L and 0.077 g/L NAA, respectively. However, the leaf length and leaf width decreased significantly in the GA3 and NAA treatments.展开更多
