| 摘 要： | 以两种不同耐密性的4个玉米品种为材料,探讨在不同密度压力下茎秆性状的变化,重点研究了地面上第三节茎秆形态及内部中央大维管束生理结构的变化,并分析了各性状与倒伏的关系。结果表明,不同类型间和同类型不同品种间对密度的反应存在明显差异。郑单958和辽单526对密度变化更加敏感。4个品种的田间倒伏率与种植密度、茎秆第三节的长粗比、茎秆中央大维管束单位视野个数呈显著正相关;与第三节茎粗、中央大维管束的平均面积呈负相关。

| Abstract: | Effects of density on stalk morphological and histological traits,especially on the morphology and physiological structure of the center big vascular bundles of the third stem from the bottom were studied by the use of four different density-tolerant maize varieties.Meanwhile,the relationship between the traits and lodging was also discussed.The results showed that the responses of stem traits of the four maize varieties to densities were different.Zhengdan958 and Liaodan526 were more sensitive to plant den... |
