| 摘 要： | 以大田单株筛选、扦插扩繁的抗蓟马无性系R-1和感蓟马无性系I-1为材料，以相邻苜蓿田自然发生的牛角花齿蓟马作为虫源，于第2茬苜蓿生长期间测定抗、感蓟马苜蓿无性系健康株和受害株的生长指标及各指标损失率。结果表明：R-1、I-1无性系受蓟马危害后，株丛的自然高度、绝对高度、再生速率、节间长、茎粗、叶面积、叶片干重、茎秆干重...

| Abstract: | The growth characteristics of clone R-1 alfalfa and clone I-1 alfalfa continuously damaged by thrips(mainly Odontothrips loti)were measured during second cutting period of alfalfa.The result indicated that natural height,absolute height,regeneration rate,internode length,stem diameter,leaf area,dry weight of stem and leaf,as well as leaf-stem ratio were decreased significantly while branching and node number were increased significantly,and the plant biomass decreased significantly indicated that compensato... |
