摘要
运用灰色系统理论对15个天彭牡丹品种进行了综合评价。结果表明:‘丹景玉楼’与参考品种的关联度最大(r=0.7547),综合性状最好,其次是‘红晕白’(r=0.7274)、‘绿晕白’(r=0.7149),综合性状优良,而‘醉西施’关联度最小(r=0.5039),表现最差。评价结果与品种的实际表现比较一致,证明在对观赏性状合理确定分值前提下,利用灰色关联度分析方法对天彭牡丹进行性状综合评价是科学可行的。
Based on the grey system theory,15 cultivars resources of Tianpeng tree peony were comprehensively evaluated.The results showed that ＇Danjing Yulou＇ had the highest relation grade（r=0.7351）with reference cultivar and the comprehensive characters of it was the best,next to ＇Hongyun Bai＇（r=0.7274）and ＇Lvyun Bai＇（r=0.7149）with excellent comprehensive characters and the relation grade of ＇Zui Xishi＇ was the smallest（r=0.5039）with the worst comprehensive characters.It showed that the result was suitable to the actual performance of cultivars and it proved that using grey relational analysis to comprehensively evaluate the cultivars resources of Tianpeng tree peony was scientific and feasible under the premise of the value of ornamental characteristics determined.
