在北京香山樱桃沟野生的十字花科豆瓣菜上发现有芜菁花叶病毒、黄瓜花叶病毒以及一种未报导过的&小白斑&病毒的复合病。小白斑病毒在20多种寄主上，包括十字花科，单独汁液接种时只能产生局部坏死病斑，不能系统侵染；单独接种而能系统感染的寄主有百日菊，只产生极轻微的深浅绿花叶，甚至有时几乎无病状。小白斑病毒能在复合病情况下系统存在于豆瓣菜中是值得注意的一种现象。

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。

Medicago sativa in the initial flowering stage was harvested and wilted for 0,6,18,or 28 h and was ensiled with different water contents(80.3%,71.2%,62.5% and 40.3% respectively) and additive mixtures.

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.

针对苜蓿雄性不育系杂交制种产量低的问题，采用杂交法对苜蓿雄性不育系进行改良，以原苜蓿雄性不育系为轮回亲本与雄性可育优良苜蓿品种杂交，分析苜蓿雄性不育系及其杂交后代种子产量的影响因素，从细胞形态学方面观察和分析杂交后代及原不育系在雌性生殖器官上的变异特点，从酶蛋白水平对杂交后代及原不育系的遗传差异进行分析，初步研究结果如下： 1、苜蓿雄性不育系与草原一号苜蓿的杂交后代不育株BC1-2，以及苜蓿雄性不育系与X′(苜蓿雄性不育系与新疆大叶苜蓿的杂种F1代)的杂交后代不育株BC1-19、BC1-21、BC1-22、BC1-23的天然杂交结荚率和人工杂交制种的结荚率和百粒重均高于原苜蓿雄性不育系。
