摘要:
为探讨南疆不同居群骆驼蓬植物叶片对生境的适应性，采用石蜡切片法制作切片，每个材料选5个观察视野，用DMB5-223I-5图像处理显微镜照相，并用Arcview3.3软件测定叶片厚度、上角质层厚度、上表皮厚度、栅栏组织厚度、海绵组织厚度、下表皮厚度及下角质层厚度。结果表明：3个不同居群中骆驼蓬叶片指数存在着显著差异；骆驼蓬-1叶片厚度、上角质层厚度、上表皮厚度、海绵组织厚度、下表皮厚度及下角质层厚度最大。各指标之间差异系数相差不大。骆驼蓬-2的栅栏组织厚度最大，其栅海比最高,为1.65。不同居群骆驼蓬叶片解剖结构的显著差异性表明不同的环境因子影响了骆驼蓬的生长发育，通过比较可知3个居群骆驼蓬适应性顺序为L-1＞L-2＞L-3，体现了植物为适应环境变化所形成的生存对策。
Abstract:
In order to explore the adaptation of the leaves of different groups of Peganum harmala plants to habitats in southern Xinjiang，we made slices with the paraffin section method,each material selected 5 fields of view,image processing using DMB5-223I-5 microscopy,and used Arcview 3.3 software to measure leaf,cuticle,epidermis,palisade and sponge tissue thickness.The results showed that there were significant differences in the leaf index.The Peganum harmala of L-1 among 3 groups had the biggest thickness including leaves,cuticle,upper epidermis,spongy tissue,the lower epidermis and lower stratum corneum.There was no significant difference between the different coefficient.L-2 had the maximum thickness of palisade tissue,and palisade spongy ratio up to 1.65.The leaf anatomical structure of Peganum harmala L.in different groups showed that significant differences of different environmental factors affecting the growth and development of Peganum harmala L..The Peganum harmala L.adaptability’s order was as L-1>L-2>L-3 through the comparison of three populations,reflected that the survival strategy of plants adapt to the changing environment.
