| 摘 要： | 为研究豆科牧草的耐荫机理，在不同遮阴处理条件下对紫花苜蓿(Medicago sativa)、草木樨(Melilotus suaveolens)、白三叶(Trifolium repens)、沙打旺(Astragalus adsurgens)和百脉根(Lotus cornioulatus)的形态和生理指标进行测定。结果表明，随着光强减弱,5种豆科牧草的株高、分蘖数、最长节间长度、根长及叶绿素含量均降低，其中白三叶变幅最小，百脉根次之；在23%透光下，白三叶的可溶性糖含量显著高于其他牧草；百脉根的丙二醛含量明显增加，而白三叶变化较小；沙打旺出现死亡现象。5种豆科牧草的耐荫性为白三叶最强，百脉根其次，紫花苜蓿和草木樨较差，沙打旺最差。

| Abstract: | A pot experiment was conducted to determine the effect of different shading conditions on morphological and physiological indexes of Medicago sativa,Melilotus suaveolens,Trifolium repens,Astragalus adsurgens,and Lotus cornioulatus for providing the basis for sowing these legumes under the forest.This study showed that the height,tiller number,the longest section between the degree,root length and chlorophyll content of five kinds of legume forages decreased as light intensity declined,in which T.repens had ... |
