Paper electrophoresis showed that the Onobrychis viciaefolia and Medicago sativa cell line transformed with A〓 synthesized agropine and mannopine, and Onobrychis viciaefolia cell line transformed with LBA9402 Bin19 only synthesized agropine.

红豆草转化系获得再生植株。LBA9402 Bin19转化系可以抗100mg／l卡那霉素。苜蓿A4转化系未能得到再生植株。纸电泳分析表明红豆草A4转化系和苜蓿A〓转化系可以合成农杆碱和甘露碱，而红豆草LBA9402Bin19转化系只能合成农杆碱。

We studied the anatomical structures related to drought resistance of the leaves of 17 varieties of Medicago sativa L. based on 12 xeromorphic indexes, did the single factor multiple comparison between two varieties in order to conclude the sensitiveness sequence of the 12 indexes to the drought, and the clustering analysis based on 3 most sensitive indexes including the leaf thickness, the main vein thickness, the palisade tissue thickness.

对17个紫花苜蓿品种叶片进行解剖，选取12项抗旱指标，采用单因素分析方法对各品种进行两两多重比较，得到各指标的灵敏度，最后以叶片厚度、中脉厚度和栅栏组织厚度3个指标为主进行聚类分析。

In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.
