Abstract

In order to study the influence of different temperature and hormone on the germination of the seeds in different area of the White Dragon River,two exogenous hormones, GA and PEG were used in this study.The germination experiment of the seed germination under different temperature gradient indicated that (1) the GA was more advantageous to the seed germination;(2) seed activity from Zhouqu was better than that of Dangchang seeds;(3) under the same temperature,as the hormone concentration increases, the germination rate showed a trend of decrease after increase first.With the increase of temperature,under the same concentration,seed germination rate showed increasing trend;Under the same temperature germination index and germination potential changes were consistent;(4) with the increase of hormone concentration and temperature,average germination time were reduced, and high concentration and high temperature could shorten seed germination time.
