对生玉米叶片蒸腾、光合若干特性的研究

Transpiration and Photosynthetic Charateristics of Opposilifolious Maize

本试验结果表明，对生玉米不仅叶片的气孔导度、蒸腾速率低，光合强度大，水分利用率高；而且，其叶片的相对含水量、水势高，有利于抵抗水分胁迫。此外，对生玉米叶绿素含量及比叶重均大于互生玉米，有利于合成。

Opposilifolious maize contains more relative water content and higher water potence in leaves due to lower stomatal conductance and transpiration rate,which could help plant resist water stress.Furthermore,opposilifolious maize could accumulate more assimilatives than alternative leaf maize resulted from higher photosynthetic rate and more chlorophyll content and specific leaf weight.
