Effect of Different Concentration of GA on the Fraxinus malacophylla Seed germination
Abstract：To treat on the Fraxinus malacophylla seed by different concentration of GA solution,then pregerminated in the artificial climate incubator for forty days and collected and analysed index of root length,shoot length and root girth.The investigation showed the following results：（1）the effect of different concentration of GA on the Fraxinus malacophylla seed germination was remarkable,and the GA solution of 200 mg/L could improve germination rate remarkable;（2）the effect of different concentration of GA on the root length and shoot length of Fraxinus malacophylla seed was not remarkable,but on the root girth was very remarkable（sig.=0.0070.01）;after multiple compared,the result that GA solution of 200 mg/L could improve root girth more remarkable than other treatments;（3）the correlate analysis of root length,shoot length and root girth obtained that the correlativityof root length and shoot length was extremely remarkable（sig.=0.0000.01）,and the correlativityof root length and root girth was remarkable（sig.=0.0190.05）.
