The Effect of Yield of Polingenesis Rice And Photosynthetic Products' Distirbution of the Flag Leaf by the Different of Phytohormore Function
摘要
Abstract
The photosynthetic products' distribution of the flag leaf at full heading stage of the ratooning rice and the different of phytohormone was studied by 14C trace technique. The results showed that; Retention rate of the photosynthate in flag leaves was 6% -26% ,72% -92% of photosynthates from flag leaf was distributed to panicle at full heading stage, distribution of photosynthates the flag leaf > the flag leaf sheathes > stems and sheathes > else leaves. Low Retention rate of the photosynthate in flag leave was good for yield of rice. The phytohormone treatment promote the photosynthates distribution rate in panicle, and increase the yield of palingenesis rice. These results showed that choosing those varieties with more panicles and the photosynthetic capacities of the flag leaf sheathes after tassel of main crop would be benefit to gain higher yield.关键词
