| 1. | A review of mikania and the impact of m . micrantha asteraceae in yunnan
云南假泽兰属植物及薇甘菊的危害 |
| 2. | Most gymnosperms retain archegonia except for the most advanced genera gnetum and welwitschia
除了买麻藤属和百岁兰属以外大多数裸子植物还保留有颈卵器。 |
| 3. | The cluster analysis with upgma suggested that the tested materials were clustered into two groups on coefficient level 0 . 46
聚类分析结果表明，在相似系数0 . 46的水平上可将14种兰属材料分为类和类。 |
| 4. | The polymorphism rate was 79 . 9 % . the cluster analysis with upgma indicated that the 14 species were also clustered into two groups on coefficient level 0 . 72
聚类分析结果表明，在相似系数0 . 72的水平上可将14种兰属材料分为两类类和类。 |
| 5. | The results of upgma cluster analysis obtained from rapd data and aflp data were in essence consistent , and also very closed to du puy & cribb morphological classification
运用rapd和aflp技术对兰属植物14种材料所得的聚类分析结果基本一致，也与dupuy & cribb分类系统接近。 |
| 6. | In this study , the genetic variations of 14 species of cymbidium were revealed by using rapd and aflp markers and the genetic variations of 13 species of dendrobium were revealed by using aflp markers
本文采用rapd技术和aflp技术对兰属植物14种材料以及采用aflp技术对石斛属13种材料进行了遗传多样性检测。 |
| 7. | Twelve primers selected from 100 random primers amplified 254 frangments in 14 species of cymbidium , in which 243 segments are polymorphic . the rate of polymorphism was 95 . 7 % . and all the segments were ranging from 200bp to 2200bp
从100个随机引物中筛选出12个随机引物，对兰属植物14种材料进行随机扩增，共得到254条带，多态性带有243条，多态性百分率为95 . 7 。 |
