| 1. | Study on lignans of dysosma versipellis
2种八角莲中鬼臼毒素类化合物的研究 |
| 2. | 6 % , the result of issr is ppb = 70 . 83 % , h = 0 . 2383 , i = 0 . 3576 . 5
八角莲和六角莲在遗传上已有有明显的分化。 |
| 3. | D . versipelis also reproduces by vegetative progagation with rhizomes . 3
八角莲还可通过根壮茎进行营养繁殖。 |
| 4. | Dysosma versipelis ( hance ) m . cheng is an important , medicinal , perennial herb
八角莲为我国特有药用植物，已被列为国家三级濒危保护植物。 |
| 5. | There were some differences in morphology between popolations of d . versipellis , owing to spatial isolation
由于种群地理分布间隔距离较大，八角莲不同种群在形态上存在一定变异。 |
| 6. | The last is its low level of genetic diversity . 7 . it is proposed that the habitats of d . versipelis should be protected
八角莲的保护首先要加强现有资源和生境的保护，其次可以人工繁殖，扩大数量。 |
| 7. | The results of analysis among the six populations ( d . versipellis and d . pleiantha ) and the five populations ( d . versipellis ) agreed with each other
2228 ） ，其它八角莲种群总方差与之接近，浙江天目山六角莲种群方差最大（ 127 |
| 8. | 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。 |
| 9. | 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。 |
| 10. | Meanwhile , numbers can be increased by artificial propagation . most populations should be sampled so as to retain as much of the genetic diversity of the species in ex situ preservation as possible
同时还要对八角莲进行迁地保护，由于八角莲的居群遗传分化较大，迁地保护中应注意在较多的居群中取样，全面保护其遗传多样性。 |
