新疆5种野生葱属植物叶片解剖比较

Leaf Anatomical Comparison of Five Wild Allium Species in Xinjiang

实验旨在比较新疆5种野生葱属植物叶片解剖,分析其适应环境能力,筛选出适宜推广的野生葱属植物。本实验以引种在新疆农业大学试验基地的5种野生葱属植物叶片为实验材料,通过石蜡切片法,在光学显微镜下观察叶片解剖结构。实验结果显示,1号、4号和6号的大维管束数越多,叶片长势越好,适应能力强。2号和3号的大维管束数越少,叶片长势越弱,适应能力差。1号、4号和6号的适应环境的能力比2号、3号强,可在适宜区域进行推广。

The experiment aims at comparing the leaf anatomy of five wild Allium species in Xinjiang, analyzing their ability to adapt to the environment and screening out the wild Alliurn species that are suitable for promotion. In this experiment, leaves of five wild AIliurn species which were introduced and cultivated in the experimental base in Xinjiang Agricultural University were chosen as materials. The anatomical structures of the leaves were analyzed and compared on the basis of the observation under optical microscope with paraffin section method. The results showed that： the larger vascular bundles the specimen No. I, No.4 and No.6 had, the better their leaves grew and the stronger ability of adaptation they had. The smaller vascular bundles the specimen No.2 and No.3 had, the weaker their/eaves grew and the poorer ability of adaptation they had. The specimen No. 1, No.4 and No.6 had stronger ability to adapt to the environment than No.2 and No.3, and they could be promoted in suitable areas.
