玉米不同叶位气孔数量及其形态的差异研究

Number and Morphology Differences of Stoma in Different Leaves of Maize (Zea mays L.)

[目的]研究玉米不同叶位气孔数量及形态。[方法]以郑单958为试验材料,研究玉米不同叶位解剖结构的差异。[结果]不同叶位叶片上表皮及下表皮气孔的数量及形态存在差异,且上表皮和下表皮气孔的大小及数量规律不同。[结论]该研究为挖掘玉米生产潜力提供理论基础。

[Objective] To study the number and morphology differences of stoma in different leaves of maize （ Zea mays L.）. [Method] With maize variety Zhengdan 958 as test materials, we studied the anatomical difference in different leaves of maize. [Result] There were differences in the number and morphology of stoma in upper and lower epidermis in different leaves. And the laws of stoma size and stoma number were different between upper and epidermis of different leaves. [Conclusion] This research provided theoretical basis for excavating the yield potential of maize.
