摘　　要：以64株紫斑牡丹为试材,对22个性状进行测定,采用层次分析法建立科学合理的紫斑牡丹观赏评价体系和油用评价体系,筛选出适合观赏、油用和油观两用的单株,以期为紫斑牡丹的科学利用提供参考依据。结果表明:观赏评价体系中I级(优)花朵直立,长势旺盛,各性状表现优良,观赏评价值高,包括12株;Ⅱ级(良)有16株,整体性状良好,适合观赏;Ⅲ级(一般)包括22株,观赏价值较低;Ⅳ级(差)有14株,各性状表现较差,不建议使用。在油用评价体系中,Ⅰ级优良单株有效蓇葖果多,单株产量和含油率高,有10株;Ⅱ级较优单株包含11株,某项性状比较突出,选择性使用;Ⅲ级一般单株有27株,建议保守使用;Ⅳ级劣势植株有8株,综合得分低,不建议使用。最终得到7株油观两用牡丹,5株观赏价值较高牡丹和3株油用价值较高的紫斑牡丹,为高大型牡丹或油观两用牡丹新品种培育提供材料基础。该研究中构建的评价体系,基本能满足生活中对紫斑牡丹观赏和油用的要求,可以有效地指导紫斑牡丹在园林中的应用。Taking 64 Paeonia rockii plants as test materials,22characters were tested,and a scientific and reasonable evaluation system for ornamental and oil was established by using analytic hierarchy process,the single plant suitable for ornamental,oil-use and oil-view were screened out,in order to provide reference for the scientific utilization of Paeonia rockii.The results showed that the flowers of GradeⅠ(excellent)were upright,higher than the leaves,with vigorous growth,good performance of each character,and high ornamental value,included 12plants.There were 16plants of GradeⅡ(good),the overall character was good,suitable for ornamental.GradeⅢ(general)included 22plants with low ornamental value.There were 14plants in GradeⅣ(poor),and the performance of each trait was poor,so it was not recommended to be used.In the evaluation system for oil use,there were 10excellent follicles per plant of GradeⅠwith high yield and oil content.There were 11excellent plants in GradeⅡ,and some traits were prominent and used selectively.There were 27plants in GradeⅢ,so conservative use was recommended.There were 8inferior plants of GradeⅣ,accounting for 14.29%.The comprehensive score was low and it was not recommended to use.Finally,7plants with high oil-view value 5plants with high ornamental value and 3plants with high oil value were obtained,which provided material basis for the cultivation of new varieties of tall and large peony or oil peony.The evaluation system constructed in this study could basically meet the requirements for ornamental and oil use of Paeonia rockii,and could effectively guide the application of Paeonia rockii in gardens.
