This study describes the multi-facet systematic evolution of the said rural community from 1907 to 2007: from the perspective of ethnic culture, it has changed from a single ethnic cultural community of Yoghur(Ethnic Yugur\'s self-name) ethnic group into a multi-ethnic cultural community with Yoghur ethnic group as the dominating majority and embracing the ethnic groups of Han, Tibetan, Tu, Mongolian and Kazak; from the perspective of language, it has changed from a community where Yoghur and Tibetan languages dominated with the local Chinese dialect and the written Chinese language as the subordinate into one where the local Chinese dialect and the written Chinese language dominate with the Yoghur language as the subordinate; in the perspective of marriage and heirship system, from a parallel operation of two systems (patrilineal heirship for official marriages and matrilineal heirship system for matrimonial forms through the head-wearing ceremony) to monogamy and patrilineal heirship; in the perspective of means of living, from animal husbandry complemented with hand knitting and camel caravan transporting to agricultural farming complemented with animal husbandry and many others; in the perspective of social organization, from a traditional tribe to a modern country society; in the perspective of political system and social management, from the customs-authority management which combined the dominating headman hereditary system under the tribal union of an imperial dynasty and the subordinating elite influence, to the resource-interest management of party-government departmental system under the ethnic minority autonomy of a nation state; in the perspective of religious faith, from a coexistence of the Gelug Tibetan Buddhism and Shamanism and the devout ancestor worship to the currently prevalent ancestor worship with religions declining and faith weakening; in the perspective of education, from the local-knowledge-oriented education to an official-knowledge-oriented education, in which modern schooling has become the major educational organization instead of the former traditional temple education; the school has replaced the temple as the "knowledge-culture" communication center; at least in the minds of the local people the central role of family education during the children\'s cultural development has also been replaced by schooling.

本研究描述了1907～2007年间，这个乡村社区的多面向的系统变迁：从族群文化的角度而言，从一个以尧乎尔为绝对主体的单一族群文化社区转变为一个以尧乎尔为主体的、有汉、藏、土、蒙古、哈萨克等组成的多元族群文化社区；从语言文字的角度而言，从一个以尧乎尔语和藏文为主，以汉语方言和汉文为辅的社区转变为一个以汉语方言和汉文为主，以尧乎尔语为辅的社区；从婚姻与继嗣制度的角度而言，从一个双系并行(明媒正娶婚行父系继嗣制度，帐房戴头婚行母系继嗣制度)的社区转变为行一夫一妻制和父系继嗣制度的社区；从生计方式的角度看，从一个以畜牧业生产为主，以手工编织和驼队运输为辅的社区转变为一个以农业为主，以牧业为辅的、多种生计方式并存的社区；从社会组织的形态而言，从一个传统部落社会转变为一个现代乡村社会；从政治制度和社会控制的角度而言，从帝制王朝的部落联盟制下头目世袭制为主，户族精英为辅的习俗—权威型控制方式转变为一个民族-国家中民族区域自治制度下以党政科层制的资源—利益型控制方式；从宗教信仰的角度而言，从一个格鲁派藏传佛教和萨满教并存，祖先崇拜之风甚烈的社区转变为寺庙衰落、信仰淡化、惟祖先崇拜仍广为流行的社区；从教育的角度而言，从一个以地方知识教育为主的社区转变为一个以官方知识教育为主的社区，现代学校教育取代了传统寺庙教育成为社区的主要教育组织形式，学校取代寺庙成为&知识—文化&传播的中心，在青少年儿童的文化成长过程中，家庭教养扮演的中心角色，至少在乡民的观念上被学校教育替代。

0Mg/L 6-benzylaminopurine was the optimal concentration of shoots quantity inducing which frequency of inducing shoots and number of shoots per explant were 100% and 11.1 respectively. 0.5mg/L 6-benzylaminopurine was the optimal concentration of shoots length inducing which average length of shoots was 12.0mm. Explant size had significantly effects on direct shoots quantity and length induction. When complete cotyledon used as explant, frequency of inducing shoots, number of shoots per explant and average length of shoots could approach to 100%, 6.7 and 17.1mm respectively. 2.0mg/L silver nitrate could significantly increase shoot quantity induction, both frequency of inducing shoots and number of shoots per explant could be as high as 97.2% and 4.2 respectively. But silver nitrate also could restrain shoots elongation.

In this research, the ~ and F2 of the crosses between a natural mutant 慪34?with super-minute grain and 慪38?with super-large grain,慡huhui 881擲huhui 527?with middle grain size were carried out to study the inheritance of the grain shape (grain length, grain width, grain thickness and grain length/width ratio) and 1000-grain weight. The main results are summarized as below:? The F1 grain length, grain width, grain thickness and 1000-grain weight of three crosses were lay between the two parents and tended to Y34, which indicated that those grain traits were all governed by the dominant effect of Y34 and influenced by both female and male parents. The differences of F1 grain length, grain width, grain thickness and 1000-grain weight of positive and negative crosses between Y38 and Y34 indicated the existence of cytogene effects.? The broad heritabilities of major grain traits were calculated.

本研究利用一份水稻极小粒自然突变材料Y34与一份水稻极大粒材料Y38、两份常规籽粒大小材料蜀恢881、蜀恢527的杂交F_1及F_2，对主要粒形性状（粒长、粒宽、粒厚、长宽比）及千粒重进行了遗传研究，根据遗传研究的结果利用微卫星标记结合F_2群分法对控制Y34短粒性状基因进行了分子标记定位，主要结果如下：●各组合F_1粒长、粒宽、粒厚和千粒重介于双亲之间且明显偏向于小值亲本 Y34，这表明粒长、粒宽、粒厚和千粒重均主要受小值亲本显性基因的控制并同时也受大值亲本核基因的影响。Y34与Y38正反交F_1在粒长、粒宽、粒厚、千粒重等性状上存在差异，表明存在细胞质效应。
