图3 玉米叶片气孔和表皮细胞的扫描电子显微照片 a、b、c为对照环境下的玉米叶片气孔特征, d、e、f为增温环境下的气孔特征。与对照相比, 增温使近轴面b和e和远轴面c和f的气孔均变得更短、更宽。同时, 增温还增加了表皮细胞的长度和宽度。标尺: 10 μm a和d、40 μm b、c、e和f。
Fig. 3 Scanning electron microscopic photographs of stomata and epidermal cells in maize leaves Shorter and wider stomatal pores were observed on both the adaxial surface b and e and abaxial surface c and f of maize leaves grown at elevated temperature than those grown at ambient temperature. In addition, elevated temperature also increased the width of epidermal cells. Bars, 10 μm a and d and 40 μm b, c, e, and f.
