Abstract:
Taking 64 Paeonia rockii plants as test materials,22 characters 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 Grade Ⅰ (excellent) were upright,higher than the leaves,with vigorous growth,good performance of each character,and high ornamental value,included 12 plants.There were 16 plants of Grade Ⅱ (good),the overall character was good,suitable for ornamental.Grade Ⅲ (general) included 22 plants with low ornamental value.There were 14 plants in Grade Ⅳ (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 10 excellent follicles per plant of Grade Ⅰ with high yield and oil content.There were 11 excellent plants in Grade Ⅱ,and some traits were prominent and used selectively.There were 27 plants in Grade Ⅲ,so conservative use was recommended.There were 8 inferior plants of Grade Ⅳ,accounting for 14.29%.The comprehensive score was low and it was not recommended to use.Finally,7 plants with high oil-view value 5 plants with high ornamental value and 3 plants 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.
