Abstract

The seed size, 1 000-grain mass, seed germination indexes after sand storage and endogenous hormone contents before and after sand storage of seeds of Meconopsis Punicea Maxim. from five locations in Qinghai, Sichuan and Gansu Provinces were determined, and the correlations between seed related indexes and geographical factors of locations were analyzed. The results show that germination potential, germination rate and germination indexes of seeds in Dezhuo Mountain in Baima County of Qinghai Province after sand storage are significantly lower than those in other locations; after sand storage, the contents of GA3 and IAA in seed of M. punicea from different locations increase, while that of ABA decreases, (GA3+IAA)/ABA ratio and germination rate increase. The 1 000-grain mass is significantly positively correlated with altitude. The comprehensive analysis result shows that the (GA3+IAA)/ABA ratio of seeds of Longge Mountain in Jigzhi County of Qinghai Province is the largest, the germination rate is the highest, the germination time lag is short, the seed length, seed width and 1 000-grain mass are large, and the seed quality is good.
