摘要
通过对引自我国北方温带草原区域的老芒麦3个品种和川西北高寒牧区3个品种同植于川西北高寒牧区的群体生育进程、植株性状和叶片组织解剖比较,结果表明,两地域品种的生态适应性有着明显差异。它们已由水热差异为主导因子分化形成了两种气候生态型。
The differences between siberian wildrye crops introduced from temperate steppe, North china and alpine pastoral areas, northwest Sichuan were studied. Through comparison of the growth and developing characteristics of the plants as well as the anatomy the leaf blade tissue of wildrye cultivars in alpine. We found that there were significant differences between introduced from the above mentioned two areas. The result indicates that there should be two climate ecotypes of Siberian wiltrye have been formed because of the differentiation of essential factors of moisture—temperature.
