Abstract:
There exist differences in the specific gravity of soybean seeds in different latitudes and different types of soybeanvarieties .The results indicated that the specific gravity of spring soybean increased along with the rising of latitude(r =0 .99＊ ＊).The specific gravity of summer soybean varieties and autumn soybean varieties were greater than that ofspring soybean varieties , however in the same area the variability coefficient of spring soybean varieties was larger thanthat of summer and autumn soybean varieties , and the specific gravity of the small size soybean was greater than that oflarge one .The specific gravity of soybean seeds was positive correlation with the days to mature(r =0 .452)and the daysto pod setting(r =0 .64), but it was significant negative correlation with the days to bloom the days to pod setting(r =0 .95＊ ＊).Slow seed filling was advantage for soybean specific gravity increasing .The correlation coefficients of sunshine, temperature and the range of temperature with specific gravity of soybean seeds were r =0 .9＊ ＊-0 .91＊ ＊ , r =0 .65 -0 .94＊ ＊ , r =0 .2 -0 .85＊ ＊separately .The changes of specific gravity of soybean seeds were relative to the genotypeof soybean varieties and climate factors during the dry materials of soybean accumulating .
