植被砼对两个早熟禾品种叶表皮细胞的影响

Effect of Vegetation Concrete on the Leaf Epidermis Cell of Two Varieties of Poa pratensis L.

  • 摘要: 研究了植被砼与地生两种生境下,草地早熟禾(Poa pratensis L.)的2个品种‘Nub lue’和‘Kenb lue’的叶片下表皮长细胞长、短细胞长、气孔长宽比以及单位视野内气孔数的差异。结果表明:在长细胞长、短细胞长、气孔长宽比的比较中,各组比较均差异显著。在气孔数的比较中,‘Nub lue’的下表皮气孔数差异显著;而‘Kenb lue’在这两种差异较大的生境下气孔数无显著性差异。

     

    Abstract: The differences of leaf epidermis of ’Nublue’ and ’Kenblue’,two varieties of Poa pratensis L.under two habitats which were the vegetation concrete,and the rural area soil were studied in this paper.Thus there were four samples totally,four parameters were concerned,which were the length of long cell,the length of short cell,the length/width ratio of gas vent and the numbers of gas vent per field of vision.It showed remarkable difference in the length of long cell,the length of short cell,the length/width ratio of gas vent between each group.As the vegetation concrete was a kind of alkaline environment,it was reaso-nable to conclude that these two varieties had relatively greater plasticity to the alkaline environment.In comparison of gas vent numbers,’Nublue’ showed remarkable difference,which demonstrated that it had a relatively large plasticity to the changes of moisture and gas,while ’Kenblue’ showed little difference which showed its greater adaptability to the changes of moisture and gas.
