| 1. | Analysis of variance for all the traits shows that there are significant differences between populations and between individuals within populations 方差分析表明:蜡梅表型性状在群体间和群体内均存在极其丰富的变异, 10个性状在群体间的差异均达显著或极显著水平。 |
| 2. | The correlations between the phenotypic traits of wintersweet and geographical and ecological factors are not significant except for latitude and annual rainfall 蜡梅表型性状与地理生态因子的相关分析表明:除纬度、年降雨量和部分性状有相关性外,其它性状和地理生态因子的相关性均不显著。 |
| 3. | The results were as follows : seven morphological traits of s . krylovii ( reproductive tiller length , vegetative tiller length , seed shape , etc . ) showed abundant variations . range and sources of variations were different 7个表型性状反应出的变异中大约有35 . 10的变异来自种群间,其余大部分变异( 64 . 90 )来自种群内部。 |
| 4. | An experiment was conducted to analyse the phenotypic diversities between and within populations in terms of ten phenotypic traits using ten populations of wintersweet from the whole distribution areas in china as experimental materials 摘要以蜡梅全分布区的10个群体为试材,对10个表型性状进行比较分析,讨论群体间和群体内的表型多样性。 |
| 5. | We did not find none of the articles report about the genetic and degenerative mechanism . the degeneration of strain is common in artificial - planting , it is one of the most urgent problems that need to solve 本实验中,运用rflp和rapd两种分子标记技术及同工酶分析技术对正常菌株和其退化菌株进行了dna和蛋白质水平的分析,以期获得表型性状的变化所涉及的dna和蛋白质水平的标记。 |
| 6. | The result of numerical taxonomy indicated that there were high phenotypic diversity among the strains isolated from the root nodules of pueraria spp . it can been seen in utilization of carbon and nitrogen sources , antibiotic resistance , resistance to dyes and chemicals , tolerance to acid , acid production , alkali production , nitrate reduction et al . the dendrogram divided all the strains into 数值分类对所有供试菌株进行了131项表型性状的测定,结果表明,葛藤根瘤菌具有丰富的表型多样性,表现在利用多种化合物作为唯一碳源、氮源能力,对抗生素、染料和化学药物的抗性,耐酸性,产酸产碱情况,硝酸还原能力等方面。 |
| 7. | The results of the cluster analysis were run by the software of mints of institute of microbiology of chinese academy of sciences . the analysis proceeded based on 103 phenotypic characteristics after 23 same characteristics were taken out . the ecological condition and phenotypic characteristic of bacteria were analysed 在进行聚类分析时,去掉完全相同的表型性状23个,对103个表型特征的测定结果进行了聚类分析,对待试菌株的生态分布、菌株表型特征的聚类情况进行了分析。 |
| 8. | Genetic diversity and phylogeny of 55 slow - growing rhizobia isolated from peanut ( arachis hypogaea ) in china were determined by analysis of host - plant range , phynotype , 16s rrna rflp , 16s rrna sequence , 16s - 23s igs rflp , rapd , rep - pcr , dna - dna hybridization homology . at the same time , the competitive nodulation capacity of rhizobia , effect of host plants and soil ph on the rhizobia were determined for screening and improvement of high effective rhizobium inoculant 本研究采用宿主范围试验、表型性状测定、 16srrna - rflp 、 16srrna序列分析、 16s - 23srdnaigsrflp分析、 rapd分析、 rep - pcr分析和dna - dna同源性分析等技术系统研究了从我国不同地域分离的55株花生根瘤菌的遗传多样性及其在根瘤菌系统发育中的地位和相互关系。 |
| 9. | Traditional approaches for genetic mapping of these so called dynamic traits have been to associate markers with phenotypes for different ages or stages of development and to compare the differences across these stages , or to use multiple trait mapping where the same character is repeatedly measured at different times 针对这些动态性状,传统的遗传作图方法是通过在不同的年龄或发育阶段利用遗传标记与表型性状进行关联分析,并比较这些性状在不同发育阶段的差异,或者通过进行不同阶段的多位点作图进行分析。 |
