| 4. | The diversities , of which 15 dioscorea zingiberensis local populations in characteristics of morphology , climate and physiology , showed the significant inner genetic diversities of the species of dioscorea zingiberensis . 2
本实验所选的15个地方居群在形态性状、生理性状和物候期等的多样性表现，说明了盾叶薯蓣存在着丰富的遗传性状的多样性。 |
| 5. | Nimal breed ? is a group of animals of common origin and of one species , similar in genetically determined economic and biological properties and morphological characteristics , demanding similar requirements as to natural and production conditions
动物品种系指一种具有共同起源，属于同一种别，在以遗传认定的经济和生物性质以及形态性状上类似，另在天然和生产条件之要求方面亦类似的动物群组。 |
| 6. | Varieties of flowering colors present cline . specially , variations of flowering colors within puer population are many and varied . longs and widths of perianths as well as longs of stamens are continuous variation of quantitative characters
结果表明：居群内各种形态性状都具有丰富的多态性，居群间具有明显的多型性；花色呈梯度变异，特别是普洱居群花色变异式样最丰富；花被片的长与宽和雄蕊的长度是数量性状的连续变异。 |
| 7. | The differentiation of the studied morphological characters shows that the differentiation of vegetative organs is greater than that of reproductive organs and the differentiation of reproductive organs does n ' t reach the notable level , which indicates that the morphological differentiation mainly occurred in the vegetative organs and is caused mainly by environment factors
在所研究的形态性状中，其差异程度表现出：营养器官的变异大于生殖器官的变异，所测量的生殖器官性状的变异均没达到显著水平，这说明形态分化主要表现在营养器官特征上，也说明营养器官受环境影响较大。 |
| 8. | The main results are summarized as follow : 1 . gross morphology on the basis of field observation and examimation of herbarium specimens , the variation pattern of all the major gross - morphology characters in machilus from zhejiang was studied , and their taxonomic significance was evaluated . the results show that the most reliable characters for the delimitation of species are the features of the leaf , the tepal and the fruits . the secondly important characters are the length and position of the florescence
形态性状分析分析结果表明：润楠属植物的分类性状主要有小枝、叶片、花序、花被片、果实等特征特性，其中花被片、叶片、果实是润楠属的重要分类性状；花序的长度及着生位置也是区分润楠属种间的重要标志之一；小枝的毛被在分类上具有第三位的重要性。 |
| 9. | By using arabidopsis thaliana as material , the study had been focused on the ion beam implantation - induced effects and the changes of the configuration . with the rapd method and the analysis of the pod , the mechanism in molecular biology and physiology were stated
以拟南芥为对象做离子注入的物理诱变，观测记载了离子束注入后供试材料的形态性状变化，利用rapd方法探讨了引起形态性状诱变的分子机理，结合同工酶分析结果，分析了离子束辐照引起的生理诱变效应。 |
| 10. | By means of polyaerylamide gel electrophoresis , peroxidase isozyme , esterase isozyme and a - amylase isozyme of dioscorea zingiberensis , which were gathered from different growing environment conditions , were analyzed . with the results of 3 kinds of isozyme analysis and the analysis of 15 populations morphology and climate , dioscorea zingiberensis were divided into 5 ecotypes . the main results were shown as follows : 1
本研究以来自我国秦岭山脉以南的甘肃、陕西、湖北、湖南、四川及云南各省的盾叶薯蓣为试验材料，通过对盾叶薯蓣的pox 、 est和a - amy3种酶的同工酶进行聚丙烯酰胺凝胶电泳分析，结合其形态性状和物候期等生物学特征，进行生态型的划分，所得结论如下： 1 |
