That between varied bacteria other than between different families there lies much difference is contrary to that in plant world 细菌界种间ftsz的差异远大于ftsz家族之间的差异，但在植物界则是蛋白家族差异大于种间差异。
6 - dmap + ccb + ethanol can effectively activate the reconstructed rat - mouse embryos . 5 ) 225 reconstructed embryos from 2 - cell to morula were transferred into 46 recipients 23 l6 dmap乙醇ccb能有效地激活种间核移植重构胚。
The seeds of ceratoides l . had great power of drought resistance and salt resistance , meanwhile , there are great differences between species , ecotypes or plants with different age 该属种子萌发时有较强的耐旱性和耐盐性，且存在种间、生态型间及株龄间的差异。
( 3 ) the pollen morphology of 19 species was investigated under sem . the results show that the morphological characteristics and exine ornamentation are not similar among species and sections （ 3 ）对该属19种植物花粉形态学观察发现，花粉形态和外壁纹饰在组间和种间存在着一定差异。
Whereas , for the natural forest consisted of native species , the niche overlap was low and the interspecies relationship was harmonious . the composition structure of community thereby was more stable 而由本地树种组成的天然林，生态位重叠小，种间关系协调，群落组成结构的稳定性更高。
The results also implied that rapd patterns within subgenus yulania were highly polymorphic . they could be effectively applied to the classification of magnoliaceae at the lower taxonomical unit 但考虑到种间形态上的差异和利于分类学特征在实际中应用，将玉兰亚属的变异类型进一步细分成5个类群。
There are no differences of soma size and cell density in the labeled neurons in the area x . the song control nuclei of emberiza rutila have more intense chat - li than that of fringilla montifringilla 栗? hvc和ra内chat样免疫反应明显强于燕雀，表明鸣啭能力的不同与免疫反应的种间差异之间具有一定的相关性。
It is one of the largest scenic spots in siniao region . the numerical classification , analysis of species diversity and interspecific association of the forest in meizi lake area were conducted . 1 本文采用样方法，设置了14个20m 20m的样方，对梅子湖的森林植被进行了数量分类、物种多样性分析和种间联结的研究。
Moutan was obtained , and is basical in accordance with the tree constructed based on morphological data . the phylogenetic relationships among species in sect . moutan was discussed in detail 最重要的是，该基因树所显示的牡丹组种间关系与前人根据形态学证据提出的牡丹组的种间关系基本吻合，并得到其他研究证据的支持。
The results indicted that species with positive association have similar biological characteristics and demand similar habitats , and the relationships among species - pairs are of significant difference in different types of community 结果表明，对生境要求相同或相似的种对表现出显著的正关联；种间关系因群落类型不同而有明显差异。
