| 摘 要： | 以超高产玉米先玉335及郑单958和普通玉米长城799为试验材料,在自然条件下,研究了不同生育时期叶面积及干物质积累与分配.结果表明,玉米植株干物质积累与生育进程的关系呈S型生长曲线;在群体干物质积累速率和最终积累量都表现出先玉335高于郑单958及长城799的趋势.苞叶和茎鞘中干物质向籽粒运转率较高,茎鞘中积累的干物质对玉米籽粒的贡献率最大.在功能上,高产玉米先玉335叶片长成以后叶片的光合作用和持续时间均高于长城799,长城799大,这对乳熟期获取较大的生物产量和提高籽粒产量有很大的作用.

| Abstract: | Leaf area and dry-matter accumulation and distribution of maize(Xianyu335,Zhengdan958 and Changcheng799) were studied under field condition.The results showed that biomass accumulation of maize plants accorded with the S-shaped curve as plants developed.And the tendency of dry matter accumulation rate and quantity of Xianyu335 was better than that of Zhengdan958 and Changcheng799.The rate of dry matter in maize bract and stem sheath transported to seed was the highest.And dry matter in maize stem sheath had greatest contribution to seed.After growing up,high-yield maize Xianyu335 had longer duration and higher efficiency in photosynthesis than Changcheng799,which was of great importance to obtain higher biomass accumulation and grain weight during milk stage. |
