Abstract

This article choose six geographic populations of Reaumuria soongocica in ZhangYe Ganzhou (ZYG), Zhangye Linze (ZYL), Wuwei Heishan (WWH), Wuwei ZhaZi (WWZ), LanZhou Renshoushan (LZR), Lanshou Jiuzhoutai (LZJ) of Gansu. Using the conventional paraffin section method and the optical microscopy method, we compare the R. soongocica leaf anatomical structure. With analysis of variance and variation coefficient, we analyze and compare the difference and variability of the each index, then using the principal component analysis and subordinate function value method, we assess and compare six geographic populations of the R. soongocica and get the superior families. The results showed that: all the indexes of R. soongocica showed significant or extremely significant differences among the six populations, the diameter of the blade, cutin layer thickness, the thickness of the epidermal cells of the ZYG is greater than the other five populations. The diameter of the blade and cutin layer thickness are the smallest in the population of the LZR, the population of the LZJ has the smallest thickness of the epidermal cells. ZYL has the maximum CTR, ZYG has the minimal. Principal component analysis showed that the first two principal components cumulative contribute rate of 87.104%, can be the basic summarized the main information for the selected indicators; the drought comprehensive ability of the six populations of the R. soongocica is WWZ>ZYG>ZYL>WWH>LZJ>LZR, overall characterized by water condition the worse the stronger the drought resistance, it is the plant through their adjustment to adapt to the external environmental conditions results; Leaf blade diameter, cutin layer thickness and thickness of epidermal cells index of the R. soongocica occupies an important place in the drought resistance mechanism.

Key words： Nitraria tangutorum; anatomical structure; xeromorphic indexes; drought resistance
