查询词典 strains

Although the conservative termed secondary homothallism inherit mode and absence of wild resources, the commercial strains encompass extremely limited genetic variation, in this paper we revealed some variations of phenotypic and genorypic characteristics among the tested strains in mycelium growth rate, field performance, esterase isozyme, soluble protein and AFLP fmgerprint.

双孢蘑菇由于自身保守的次级同宗配合遗传方式以及长期野生种质资源的匮乏，造成现有栽培菌株之间相似性程度较高，尽管这样，本试验采用不同方法，从菌丝生长速度、农艺性状、蛋白质以及基因组各方面系统地反映了双孢蘑菇主要商业栽培菌株间的表型及遗传差异性，为双孢蘑菇种内杂交育种提供了科学依据。

It implied that the Fi single plant of stable strains had been homozygosis genetype plant, and the basic genetic unit of early generation stability was F single plant or F2 strains.

Four items of water quality has been collected in field surveys, including PH value, dissolve oxygen, electric conductivity level and turbidity level. Furthermore, 19 species of freshwater fish have been found, of which 10 species are local strains, 4 species are foreign strains, and 1 species is a hybrid strain. The results of calculating and analyzing the water quality index and Index of Biotic Integrity indicate that WQI is estimated from excellent to fair, while IBI is estimated from fair to poor. It has been illustrated that two indexes show different assessment results. Of those WQI index is more reliable than the IBI. IBI index need further modification for the use of water quality assessment in the Tou-Bien-Ken Creek.

现场采集水质资料共4种，包含pH、溶氧、导电度及浊度，鱼类共计19种，其中原生种10种、外来种4种、杂交种1种，经计算之水质指数及生物整合指数研究分析结果发现，调查测站WQI水质评等由特优至中等，IBI评等由中等至差的等级，显示两种指数评分具有差距，WQI指数之评分结果较IBI正确，IBI指数须经修正才能更适用於头汴坑溪之水质评估。
