摘　　要：以九单48和松玉656两个玉米品种为材料,对幼苗期不同时期各叶片表皮细胞和气孔的量化指标进行较系统的研究。结果表明,在试验范围内,各叶片上下表皮细胞和气孔的长与宽均表现为随着叶片的生长而逐渐增大;各叶片在初次取样时其上下表皮细胞和气孔长与宽的数值是相近的;上表皮细胞短而宽,下表皮细胞长而窄;上表皮气孔长小于下表皮的气孔长、上表皮气孔宽大于下表皮的气孔宽;各叶片上下表皮细胞和气孔的面积均表现为随叶面积增加而逐渐增大;上表皮细胞面积小于下表皮细胞面积,而上表皮气孔面积大于下表皮气孔面积;上下表皮细胞和气孔的密度均随叶面积增加而逐渐减小。The quantitative indicators of epidermal cells and stomata for different periods of each seedling leaves were systematically studied using two maize cultivars Jiudan48 and Songyu656 as materials. The results showed that, in this study, the length and width of epidermal cells and stomata on each leaf upper and lower epidermal were increased gradually with the leaf growth. The values for the initial sampling of the length and width of upper and lower epidermal cells and stomata of each blade were similar. The upper epidermal cells were short and wide, the lower epidermal cells were long and narrow; the stomata on the upper epidermis were shorter than the lower epidermal stomata, but the stomata on the upper epidermis were wider than the lower epidermal stomata; the areas of upper and lower epidermal cells and stomata for each leaf were increased gradually with the increase of the leaf area; the areas of upper epidermal cells were less than that of lower epidermal cells, but the areas of the stomata on upper epidermis was larger than that of lower epidermis; the cell density and stoma density of the upper and lower epidermis were decreased gradually with the increase of leaf area.
