| 1. | Allozyme genetic investigation on robinia pseudoacacia 马尾松种子园的遗传多样性与父本分析 |
| 2. | Allozyme diversity in natural populations of betula alnoides from guangxi , china 广西区西南桦天然居群遗传多样性的研究 |
| 3. | Results of allozyme cluster analysis based on nei ' s ( 1972 ) genetic distance agreed with the results of morphological cluster analysis 以nei ( 1972 )的遗传距离得到的聚类分析结果与形态学性状获得的结果基本一致。 |
| 4. | The tree based on the results of allozyme and issr data shows that d . pleiantha is on one branch distinguished from all populations of d . versipelis 根据等位酶分析和issrs结果构建的系统树,相对于八角莲各居群,六角莲都单独分为了一支。 |
| 5. | The difference of two cluster diagraphs also explained the similar trend . affected by the grazing stress , patterns of variation in coding allozyme gene - locus and genome were different 二者聚类顺序不同可以进一步说明,放牧压力作用使种群在等位酶的基因位点与全基因组序列的变异模式不同。 |
| 6. | It was sampled from one population in zhejiang province . the studies were carried out by life history analysis , breeding system analysis , morphological analysis , allozyme analysis and issr analysis 生物学特性主要研究了八角莲的生活史和繁育特性,而遗传多样性则从等位酶和issr两种分子水平分别进行了研究。 |
| 7. | Deterioration series of populations were analyzed by the means of allozyme and rapd . the results showed that as the deterioration of grassland became heavier , genetic diversity would drop , but there was no distinct linear correlation between genetic diversity and deterioration degree 等位酶和rapd标记分析退化系列种群,其遗传多样性随退化程度加重有降低的趋势,但与退化程度无明显的线性相关。 |
| 8. | Second , the population genetic structure and genetic diversity of e . mollis were studied by using allozyme eletrophoresis and the electrophoretic data for 6 loci from 3 populations being xiangning , yicheng and pinglu populations in shanxi were got . the level of polymorphism was relatively higher than that of the insect - pollinated outcrossing species ( he = 0 . 375 ) 用等位酶电泳法和biosys - 2软件对山西翅果油树种群的遗传结构和遗传多样性进行了研究,通过对3个种群的6个等位酶位点的电泳分析,结果表明: 5个位点为多态位点, 1个单态位点。 |
| 9. | In this study fourteen wild lespedeza germplasms were collected from beijing , shanxi and heilongjiang province in 2001 and 2002 , and a nursary of these germplasms was established . genetic diversity of the lespedeza populations were studied at morphological . allozyme and rapd levels 本研究以2001 - 2002年从北京、山西和黑龙江三个地区收集的14份野生胡枝子属植物为材料,建立种质资源圃,从形态学标记、等位酶标记和rapd标记三个方面进行了胡枝子属植物遗传多样性的研究。 |
