增温处理后，夏蜡梅叶片中SOD、POD活性增强，说明夏蜡梅幼苗的抗氧化酶系统具有较强的保护能力。

The activity of SOD and POD in the leaves increased by the simulated warming , which indicated that the antioxidant system in the seedlings of S. chinensis was effective .

第一部分是以中国特有濒危植物夏蜡梅（CalycanthuschinensisChengetS.Y.Chang）为载体，进行濒危植物物种保护鉴定的分子探针开发；

In the first part species-specific molecular primers were developed for the authentication of an ornamental landscape species , Calycanthus chinensis Cheng et S. Y.

夏蜡梅三个居群总的多态位点百分比（P（0.05））与平均基因杂合度（He）分别为44.1%和0.229，表明其遗传多样性水平偏低。

At the species ' level , the percentage of polymorphic loci ( P0.05 ) and gene heterozygosity ( He ) of Calycanthus chinensis are 44.1 % and 0.229 respectively , which indicate a lower level of genetic diversity in natural populations of Calycanthus chinensis .

通径分析显示，土壤有机质、土壤pH值对夏蜡梅叶片游离蒽醌含量起正作用，土壤氮、C/N、土壤磷起负作用。

Fifth , the path analysis showed that soil organic matter and pH value played positive roles in the content of dissociated emodin in the leaves of C. chinensis , while soil nitrogen , C / N and phosphorus played negative roles .

AMOVA分子差异分析表明夏蜡梅群体间遗传分化程度高，71.91%的变异存在于群体间，28.09%的变异存在于群体内，群体间的基因分化系数（GST）为0.6274。

Analysis of molecular variance ( AMOVA ) demonstrated that the genetic differentiation among population was high . Variation among population occupied 71.91 % , while that within population occupied only 28.09 % .
