| 摘 要： | 利用光学显微镜,分别对扎龙湿地不同地区羊草(Leymus chinensis)的叶片上、下表皮微形态进行了观察、比较和分析.结果表明:生长在不同区域中的羊草表现出了不同的适应干旱的特征,主要表现在刺毛的多少、长短上;泡状细胞随干旱的程度而递减.羊草在进化过程中适应不同的生态环境造成了其叶表皮微形态的多样化.

| Abstract: | The epidermal micro-morphology of upper and lower epidermis of leaf of Leymus chinensis from different region of Zhalong Wetland were examined and analyzed under light microscope(LM).The results showed that Leymus chinensis from different region adapted to the different characteristics in the drought.That main displayed the number and length of the prickle hairs.Bulliform cell reduced with the extent of drought.Because of evolution and the differen environmental,there exists distinct morphological variation... |
