Analysis and evaluation of flower and fruit characteristics of different Prunus mume cultivars
[Objective]Prunus mume is an ornamental and fruit plant widely cultivated in China.The aim of this study is to select and evaluate P.mume cultivars with both flower and fruit functions,so as to provide basis for fruit processing and utilization.[Method]The 28 P.mume cultivars were selected as research object.Flower traits,fruiting capacity,fruit quality indexes were measured and evaluated by principal component analysis and cluster analysis.[Result]The flower diameter of 28 cultivars ranged from 19.14 to 31.38 mm,with 5-23 petals.White cultivars accounted for the largest proportion.There were significant differences in fruit setting among P.mume cultivars,with'Lijiang Zhaoshui','Yulong Hongfei'and'Yulong Feixue'being more prone to fruit setting.In addition,there were differences in fruit appearance and internal quality among different P.mume cultivars.Principal component analysis was conducted on 28 cultivars,and 16 indexes were simplified into 4 common factors,with a variance explanation percentage of 82.72％.The comprehensive scores showed that'DieYuchong','Gu Li hong','Danfen Chuizhi','Hongyan Zhusha','ZAFU-CZ02','Jiangmei'and'Lijiang Zhaoshui'had higher scores.Cluster analysis showed that when the Euclidean distance was 24,P.mume cultivars could be divided into 6 groups.Based on the results of principal component and cluster analysis,4 excellent varieties for both flower and fruit use were selected,including'Danfen Chuizhi','Lijiang Zhaoshui','GuLihong',and'Hongyan Zhusha'.[Conclusion]There are differences in flower traits,fruit setting and fruit quality among different P.mume cultivars.According to the comprehensive characteristics of the flower,fruit yield,and fruit quality,it can be concluded that'Danfen Chuizhi'and'Lijiang Zhaoshui'are easy to bear fruit and have the best comprehensive fruit quality.They are excellent suitable for both flower and fruit.'Gu Lihong'and'Hongyan Zhusha'have bright flower color,with semi double petals and easy to bear fruit.They are suitable for flower and fruit production.[Ch,6 fig.6 tab.30 ref.]
