| 摘 要： | 以早、中、晚不同熟期小麦品种为试材,研究干物质积累和分配特点。结果表明:各品种干物质的积累均按logistic曲线变化,呈现出"慢—快—慢"的增长规律,但生长发育过程中不同熟性小麦品种各器官的分配量及分配比例存在较大差异。早熟品种K35平均干物质积累速率、最大积累速率比较低,达到最大积累速度的时间较晚,在灌浆期有显著的生育优势。晚熟品种干物质积累平均速率、最大积累速率均较高,具有较强的生产潜势。 |

| Abstract: | The characteristics of the dry matter accumulation and assignment were investigated with the early,middle and later mature wheat cultivars.The results showed that the dry matter accumulation of the wheat cultivars with different maturing dates were all according to the logistic curve and showed slow-fast-slow.There were significant differences on the assignment of dry matter to every part of different wheat cultivars.The average and the maximum accumulation velocities of early-maturity wheat K35 were lower than that of other varieties,and it was almost the latest one anniving at the maximum accumulation velocity.It also had distinctly predominance in filling phase.The later mature cultivars had higher average and maximum accumulation velocities and production potential. |
