通过两年对小麦品种籽粒灌浆的研究,揭示了因灌浆期籽粒充实速率大小和持续期长短决定了品种间千粒重的差异。由粒草干重最大值与粒重和饱满度间的显著正相关,初步探明营养生长与籽粒发育间的数量关系。提出用充实指数计量小麦品种的灌浆能力和用饱满指数度量源库的平衡程度。
After two years of research on grain filling of wheat cultivars, it was revealed that the difference of 1000-grain weight among cultivars was determined by the grain filling rate and the duration of grain filling. The significant positive correlation between the maximum value of grain dry weight and the grain weight and fullness of grain grass initially ascertained the relationship between the number of vegetative growth and grain development. It is proposed to measure the filling ability of wheat cultivars by the enrichment index and to measure the balance of the source stocks by the full index.
