| 中文摘要: |
| 为揭示山旱地春油菜品种由于角果成熟期籽粒充实速率大小和持续期长短不同而引起品种间千粒重的差异问题,2000～2001年,对不同品种籽粒充实过程进行了研究,初步探明了旱地春油菜营养生长与籽粒发育间的数量关系。提出用充实指数计量旱地春油菜品种籽粒的充实能力和用饱满指数度量源库的平衡程度。 |
| 英文摘要: |
| To reveal the differences of seed weight among varieties of dry-land spring rape caused by the divergences of filling rate and duration in the cours e of siliquous maturity, this paper illustrates the quantit ative relationship between nutrition growth and kernel development of spring rape through the study on the filling process of different kernel types. The filling index and the satiation index are proposed to measure the kernel fil ling ability of dry-land spring rape and to evaluate the balance degree of sour ce and storage, respectively. |
