| 摘 要： | 采用称重法研究了杂种与常规品种开花后顶三叶、鞘、茎节间干物质变化过程的结果表明,杂种小麦营养体内光合产物的生产量具有优势,单茎增长量较常规品种多22%,但由于输往穗子的光合产物比常规品种少10%,因而杂种产量优势不显著。

| Abstract: | The experiment on the dry matter in three top-ajoints, their leaves and leaf-sheaths of the conventional-wheat and hybrid-wheat during the period after anthesis were carried out. It is showed that the amount of photosynthestic dry matter in the vegetative organ of hybrid-wheat was higher than that of the coventional wheat by 20%;but the amount of photosynthestic dry matter of hybrid-wheat entering into the weal-spike was lower than that of coventional-wheat by 11%.Because of the un-smothness in its transportation channel so the preponderance of hybrid-wheat was not fully expressed by the wheat yield. The higher amount of photosynthestic products in the hybrid-wheat cultivar resulting from the bigger green area which had a longer function of photosynthesis and a higher content of chlorophll. The un-smothness in the transportation charmed of the hybrid-wheat was due to the vegetative part which had a higher water-content and a lower water-losing speed,also because a smaller difference of the water-contents between its vegetative and reptuductive parts during the seeding-filling period. |
