On the poet's choice, mainly be decided by two standards, one is the popularity and influences of works; two is the meaning of the creations development that it create for the whole colony. Owing to above two standards, the writer chooses seven writers to launch the treatise, they are Jidi Maja, Jimu Langge, Luwu Laqi, Ma Deqing, Aku Wuwu , Asu Yuer, Eni-Mushashijia. In discussing the process, the writer used the nationality and Poetics of the poem as the latent clues, emphasized to inquiry into three main roads and three main realms. On the article structure, the full text mainly is divided into two parts, one is the concrete imago analysis to each poet creations, two is upon the analytical foundation the integration of the theories, with this the treatise could be united into an organic whole. In regard to the conclusion, we educe the characteristics of the colony is deep consciousness to the nation culture, also extensive exploration and attention to poetics. The blemish is the inside emotion and sensibility is similar or duplicate and that the creation pattern is narrow. The main develop threads of the colony are upon the female clan culture the diverse poem skill investigation, its nation culture value tropism present the rising spiral type of return- leave- return again.

在研究方法上，本文以意象分析法为贯穿全文的主要方法，通过对意象的具体分析来透视凉山诗群的诗歌世界；在诗人的选择上以其作品的影响力及意义为标准，选择了这一诗群的七位诗人展开论述，他们分别是吉狄马加、吉木狼格、倮伍拉且、马德清、阿库乌雾、阿苏越尔、俄尼·牧莎斯加；在论述过程上，笔者以诗歌的民族性和诗性作为前后贯穿的潜在线索，着重探讨了这一诗群创作的三个主要倾向和三个主要领域，前者详论，后者略述，具体表现在对前三位诗人的论述以诗人论的形式详细展开，探讨他们所代表的凉山诗群发展过程中的三个主要创作倾向，即民族文化的深层开掘、诗艺的实验性探索和艺术哲学的尝试性建构，对后四位诗人的论述则以主题的方式展开，探讨他们所代表的凉山诗群在爱情诗、乡土诗和文化诗三个领域的探索；在文章结构上，全文主要分为两大板块，一是对各位诗人创作的具体意象分析，二是在前文分析的基础上进行理论的整合，以此将前面散珠似的论述贯穿成一个有机整体；在结论上，我们通过整合得出：1、凉山诗人群新时期以来诗歌创作的大致发展脉络：在母族文化的基质之上的多元诗艺探索，其民族文化价值取向呈现为回归—离去—再回归的螺旋式上升形态；2、新时期彝族凉山诗人群汉语诗歌创作的特点，即民族文化意识的深层自觉，对诗性的关注和探索；3、新时期彝族凉山诗人群汉语诗歌创作的缺陷，即情感意蕴的雷同和创作格局的狭小。

The results showed:among the 7 isolates, five isolates of HY3、GY1－3、ZJ1－1、HP1、FC3 had same colony shape, irregular shape, liquidlike, slimy, opacity with smooth surface;the other two isolates had same shape, irregular shape, dry, opacity with coarse surface. By inoculating eucalyptus with the 7 isolates, the plants were infected apparently, and the young plants of eucalyptus in control experiment with tap water were not infected. By cultivating eucalyptus cuttings with the bacterial suspensions without EPS, the incidence of disease was very distinct,but compared with the former bacteria suspension,the incidence of disease has decreased at different degrees. By screening out two isolates of strong pathogenicity and two isolates of weak pathogenicity from the 7 isolates,making the bacterial suspensions with them to inoculate the young plants of eucalyptus, two treatments of cutlings and ramets with rats were set with 5 repetitions in every treatment, the results of data analysis showed: for the cutlings, the bacterial contents in upper and middle parts、upper and lower had significant difference;for ramets with roots, the bacterial contents in upper, middle parts, lower had significant difference between each other; For both the cutlings and ramets with roof, the bacterial contents in xylem and phloem had significant difference. The interaction between vertical and horizontal parts for the bacterial content had significant difference. For the two isolates of HY3 and 93B which were screened out at last,their activities of the cellulase were: 1.955ug/ and 1.288ug/ respectively, and had significant difference; the activities of pectase were: 1.325 ug/and 1.24ug/ respectively, and had no significant difference. The content of EPS extracted from the two isolates of HY3 and 93B was very different: 7.08x10-8ug/cell and 5.17x10-8ug/cell.

ABSTRACT It is because that the excellent acceptors for maize transgenic engineering are insufficient in our country, especially in the southwest mountain areas of china and hereditary variation regularity for the two characters such as efficiency of embryonic callus induction and number of regenerating plant (these two characters were abbreviated to the nduction efficiency and number of regenerating in the following of the paper, respectively), which hint the maize culturing capacity, is not very clear. Therefore, aiming at picking out superior acceptors, we had made systematic researches on the two characters with combing traditional quantitative-character genetic analyzing methods such as single-factor genetic mating design, diallel crossing genetic design, genetic effect analyzing method and the modern molecular locating method such as QTLs'. The main results are followed.(1) 50 superior inbred lines and about 30 crosses in our country, especially in the southwest of China were used for identifying and selecting the superior genotypes in the above two investigated characters under the same culturing condition in 2000 and 2001. There was very significant difference among the genotypes in the both characters. But the two characters were not certainly related. Some genotypes such as 18-599 and 18-599 were very good in them. For some ones such as zong 31, induction was higher than 18-599 and 18-599 in the efficiency, but it was only 1/3 to the later in regenerating number. In some genotypes such as S37, R08, R15, P138, A318, induction efficiency was just about 3% and scarcely any regenerating plants were got. On the whole, hybrids acted better than inbreeds in the both characters.(2) Two kind of inbreeds were selected as parents of the Griffing's method 1. 18-599 and 18-599 and the inbred line zong 31 are one kind because they are not only superior in the characters of maize cross breeding, such as CA, resistance to disease and the important agricultural characters, but also excellent in transformation characters as the induction and regeneration.

针对我国、特别是西南山地所需玉米转基因工程育种优良受体极为匮乏和反应玉米幼胚培养能力的2个主要性状，即玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数的遗传变异规律十分不清楚的实际情况，本研究从筛选玉米转基因工程所需要的优良受体入手，采用单因素遗传交配设计、双列杂交遗传交配设计、世代基因效应等传统数量性状分析方法，以及现代分子标记定位主效QTL分析方法，对玉米幼胚胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个性状进行了较为系统的分析研究，取得以下主要研究结果：(1)于2000年和2001年通过对我国、特别是西南地区近50份优良自交系和近30个杂交组合，在相同培养条件下，对幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数等2个幼胚培养能力性状进行了筛选与鉴定，发现玉米不同基因型具有完全不同的幼胚培养胚性愈伤组织诱导率和胚性愈伤组织绿苗发生数，但幼胚培养胚性愈伤组织诱导率与胚性愈伤组织绿苗发生数并不具有必然的相关关系，有的基因型，如自交系18-599和18-599在胚性愈伤组织诱导率和愈伤组织绿苗发生数等2个性状都表现相当优异；有的基因型，如自交系综31，仅幼胚培养胚性愈伤组织诱导率性状表现高于19-599和18-599，但在胚性愈伤组织绿苗发生数这一性状则与它们有相当大的差距，仅为19-599和18-599的1/3左右；有的基因型，如S37、R08、R15、P138、A318等玉米自交系不仅幼胚培养胚性愈伤组织诱导率很低，平均仅在3％左右，而且胚性愈伤组织绿苗发生数表现也很差，基本上没有分化成苗。
