摘要
对三色苋叶片气孔的分化、密度、老化等进行了研究 ,结果表明保卫细胞母细胞的分化始于叶长 1 3.8mm的未展开心叶上 ,伴随着叶的展开 ,气孔成熟开孔。叶片气孔的分化是持续进行的 ,气孔密度的最大值出现在叶长 2 7mm、叶面积 1 .1 8cm2 时。
We researched on the stomatal differentiation,stomatal density and stomatal aging in Amaranthus tricolor leaves. Result shows that the differentiation of mother cell in protective cell begins from folded leaves that are 13.8 mm long. With the leaves unfolding, stomata are mature and open. The differentiation of stomata is continuous process in amaranth leaves. When leaf's length is 27 mm and leaf's area is 1.18 cm 2, the stomatal density is max. The stomatal aging and degradation are also found in the old leaves of the lower part.
