Abstract:
A.tetraphylla from Guizhou was used as the test material.By using randomized trials and statistical methods，A.tetraphylla seed morphology，yield，1 000-grain weight，germination rate，germination potential and physiological-biochemical indexes in different harvesting stage were determined and analyzed.In order to reveal the suitable harvest time for A.tetraphylla seed in Guizhou，lays the foundation for establishment of the quality standard of A.tetraphylla seed，breeding and the cultivation of seedlings.The results showed that according to the observation，the seed size of A.tetraphylla increased most rapidly 15-25 days after the flowers withered，and the growth rate of seed size slowed down afterwards.The seed germination rate did not change at 10-20 days after the flowers withered，but increased rapidly at 25-35 days.The 1 000-grain weight was higher from 25-30 days after the flower faded.In the process of harvesting fruits on 35 days，the seeds were easily shed from the fruit openings，and the average number of seeds decreased significantly.The change range of water content in the seed development of A.tetraphylla was less than 30-35 days after the flower faded.The soluble sugar content of seeds did not change much 10-15 days after the flower faded，but increased rapidly after 15-20 days，and remained almost unchanged at 20-35 days.SOD activity reached its highest at 30 days after the flowers withered.
