摘要
以不同的小麦品种为材料，研究了灌浆特性与粒重及粒重优势的关系。结果表明，小麦粒重及粒重优势与籽粒最大灌浆速率、平均灌浆速率和籽粒最大体积呈极显著正相关；通径分析表明，籽粒最大体积对粒重及粒重优势的直接作用最大，其次为平均灌浆速率。
With 16 cultivars with different agronomy characters, the studies of the effects of grain filling characters on the grain weight and its heterosis were carried out. The main results showed that the grain weight and its heterosis were significantly and positively correlated with grain filling rate, maximum grain filling weight and kernel volume. Path analysis showed that the maximum direct effect to the grain weight and its heterosis was obtained from grain volume, middle direct effect from grain filling rate and the low effect from grain maximum filling rate.
