查询词典 grade crossing

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。

Basic fertilizer (organic fertilizer 500kg/667m2) add medium-term (organic fertilizer 500kg/667m2) facilitates favor to high-yield with the best conprehensive quality;density（40cm×60cm）with the highest yield; plastic mulching can significantly increase plant height, leaf width, leaf length, mature leaves, basal culm thickness, the first grade cormels weight and the second grade cormels weight; the first grade cormels of red sprout clocasia escalenta weight and yield had the obvious phenomenon of rapid growth in the medium expansion period of clocasia escalenta (July 14); an appropriate increase in plant height and stem yield was conducive to the increase in corn yield, the increase in corn yield favor to the first grade cormel numbers, the first grade cormel yield, the second grade cormel numbers, the second grade cormel yield, and thus obtain a higher yield.

Through difference significance tests and analyses, it finds that (1) man students more possibly form identity achievement, and woman students more possibly form identity foreclosure and identity diffusion; and (2) the difference of self-identity status between man and woman students is associated with various domains; and (3) self-identity status between man and woman students have some similarities that identity exploration has the same importance to both; and (4) grade-one is a period when students face up to more identity crises, and grade-two is key period of identity formation, and grade-three is a developmental period of identity that provides the basis for re-solution of the emergence of new identity crises in grade-four;(5) there is a gradually enhanced direction from lower self-identity statuses to advanced ones from grade-one to grade-three, but there is also a direction that reentry into the identity crisis by grade-four. It indicates that the identity achievement formation does not mean the end of development of self-identity and proves that there is a continuous MAMA cycle in self-identity development; and (6) that students self-identity status mainly is identity moratorium provides some evidence for which there is a Moratorium in student development, and which self-identity formation is not easy; and (7) the development of student self-identity is associated with various domains, what students pay most attention to firstly is vocation, secondly life philosophy, and lower interesting in political and religious domains in ideology; for relational domains, students pay more attention to dating and friendship compared to sex role and recreation domain.

通过差异显著性检验和分析发现：(1)男生更可能形成成就型同一性，女生则更可能形成排他型和弥散型同一性；(2)男女大学生自我同一性的差异与不同的领域相关；(3)男女大学生自我同一性也存在相似性，同一性探索对于男女大学生同样重要；(4)大学一年级是同一性危机面对较多的时期，二年级为同一性形成的关键期，三年级为同一性的发展期，所形成的同一性为四年级所出现新的同一性危机的解决提供了基础；(5)从一年级到三年级存在从低级的自我同一性向高级的自我同一型转变的渐进增强，但到四年级又有重新进入同一性危机的趋势，说明大学生成就型自我同一性的形成并不意味着自我同一性发展的结束，证明了自我同一性发展的MAMA周期持续存在的特点；(6)学生自我同一性状态主要还处于延缓型同一性状态，进一步证明大学生发展心理合法延缓期的存在，以及自我同一性形成不是一件很容易的事情；(7)大学生自我同一性的发展与领域相关，大学生较为关注职业领域，其次为人生观领域，而对政治和信仰领域兴趣较低；另外，大学生对友谊、交往领域较为关注，对性别角色和活动领域关注程度相对较低。
