Abstract

The characteristics of seed germination of six Sophora moorcroftiana provenances were examined, and the relationships among seed size, germination and elevation were analyzed. The results indicated that: 1) the number of seed per pod varied from 2.96 to 4.50, the mass of 1 000 seed ranged from 30.639 g to 47.415 g, the seed length and width varied from 4.314~4.926 mm and 3.244~3.693 mm, respectively, and the ratios of seed length to width ranged from 1.306 to 1.383. The analysis of variance showed that except the ratios of seed length to width, there were significant differences in the number of seed per pod, the mass of 1 000 seed, the seed length and width among provenances; 2) the percentage of seed germination changed from 43.16% to 90.03% among six provenances, of which the highest was Sajia provenance and the lowest was Mirui provenance; 3); the difference in the start time of seed germination among six provenances was only one day; the persistent time of seed germination varied from 14 to 23 days and the maximum difference in it among the six provenances was 9 days; the summit of seed germination ranged from 17 to 27 days, and it was a large difference among provenances, of which the longest was Sajia provenance and the shortest was Langxian provenance; 4) with increasing altitude, the number of seed per pod significantly declined (R=-0.844 3, PR=0.614 3, PR=-0.883 6, PR=0.804 7, P<0.05).
