新疆5种野生葱属植物叶片解剖比较

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。

Leaf Anatomical Comparison of Five Wild Allium Species in Xinjiang

This experiment aims at comparing the leaf anatomy of five species of wild allium plants in Xinjiang and analyzing their environmental adaptability to screen out the wild allium plants suitable for the promotion. [Method] In this experiment, leaves of five species of wild allium plants introduced and cultivated in the experimental base of Xinjiang Agricultural University were chosen as materials to observe their anatomical structures under the optical microscope with paraffin section method. [Result] The results showed that: In specimen NO.1, there were 15~17 large vascular bundles and 45~48 small vascular bundles, while the number of large catheter was 7~10 and that of small catheter was 27~29; In specimen NO.2, there were 5~9 large vascular bundles and 24~26 small vascular bundles, while the number of large catheter was 5~9 and that of small catheter was 8~19; In specimen NO.3, there were 9~11 bundles of large vascular and 19~20 bundles of small vascular, while the number of large catheter was 7~8 and that of small catheter was 3~5; In specimen NO.4, there were 13~14 bundles of large vascular and 20~22 bundles of small vascular, while the quantity of large catheter was 5~10 and that of small catheter was 10~12; In specimen NO.6, there were 8~14 bundles of large vascular and 18~26 bundles of small vascular, while the quantity of large catheter was 6~10 and that of small catheter was 15~20. [Conclusion] It is proved that the specimen NO.1, NO.4 and NO.6 have stronger environmental adaptability than NO.2 and NO.3, and they could be promoted in suitable areas.
