Numerical value of aforesaid 2 index near contrast with 4 samples , happen to polarization in the individual of sample 两项指数数值比较接近。说明在这几个基因座位上已明显发生变异，出现种内分化。
Seed - coat micromorphological features seem to be quite constant within species and thus are of significant value in the delimitation of some species 种皮微形态特征在种内相当稳定，在一些种的划分上具重要意义。
Acomparative biomechanical study of branch locking intramedullary nail and three kinds ofother internal fixation devices in treatment of humeral fractures 分叉交锁髓内钉和其它三种内固定器材治疗肱骨骨折的生物力学比较研究
High performance liquid chromatography ( hplc ) was used to detect endogenous phytohormones ( iaa , ga3 , aba , zr ) of nai - plum fruits ( prunussalicina lindl . var . cordata ) 摘要本文采用了高效液相色谱( hplc )法测定柰李果实四种内源激素( iaa , ga3 , aba , zr )含量。
2 . the results of rapd analysis showed rapd analysis could not only be used in species classification , but also in isolates differentiation . 3 供试菌株随机扩增dna多态性研究表明， rapd技术不仅可有效地用于侧耳种内不同菌株的区分，而且可用于不同种的分类鉴定。
M , tl , t4 , t5 , t6 , and t8 were identified by 7 specific bands which were amplified through primer pair of p53 / e44 , the most samples were identified using these specific bands of p53 / e44 78 ，总体来看地域对天麻种内多态性有一定的影响，但不如rapd聚类结果那么明显，野生品系与栽培品系间的差异比较显著。
There are mutual interference among the third instar larvae of episyrphus balteatus de geer , and the searching efficiency decreases and the intensity of scrambling competition increases with increase of its density 黑带食蚜蝇3龄幼虫存在着种内干扰，其寻找效应随着自身密度的增加而降低，其分摊竞争强度随着自身密度的增加而增加。
Liu et wu . as a result , anatomical characteristics of foliar and wood showed a remarkable inter - and intra - specific variation , but the interspecific changes in leaf surface and leaf anatomical features indicated a clustery trend 结果表明，各解剖特征的种间和种内差异较为显著，叶表面结构特征和叶解剖特征的种间变化显示了一定的规律性。
According to our observation , the variation of the botanical characteristics in some varieties of jinyinhua is big , and the macro scopic characteristics of each variety of jinyinhua are also variable in some degree 对川产金银花进行了基原鉴定、性状鉴定，发现有的原植物种内变异较大，每种金银花的性状特征在一定程度上也是可变的。
