| Abstract: | Average single seed quality of Sabina virginiana of Nebraska seed source was 7.72 mg,and standard deviation was 2.345 3 mg,the difference of seed size was great disparity,the difference between minimum size and maximum size of seed quantity was more than 10 times,single seed quality was more than average standard disparity account for 14.78%,account for 1.17%.Deviation coefficient of single seed quality was 0.303 9,its bias coefficient was 1.018 9,distribution presented curve of partial normal,and seed size had higher variation degree. |
