不同品种群牡丹年生长量研究

目的]对不同牡丹品种群的年生长量进行研究。方法]以洛阳地区四大品种群牡丹(中原品种群、西北品种群、日本品种群及欧美品种群)为试验材料,研究其枝条年生长量和年实际留存量及实存率。结果]4个品种群枝条年平均生长量从大到小的顺序依次为欧美品种群、西北品种群、日本品种群、中原品种群;年实际留存量的顺序从大到小依次为西北品种群、日本品种群、欧美品种群、中原品种群;平均实存率的顺序从大到小依次是西北品种群、日本品种群、中原品种群、欧美品种群,西北品种群牡丹表现突出。结论]该研究为制定合理的栽培管理技术方案及牡丹新品种选育提供了理论依据。

Annual Growth of Different Ciltivar Groups of Peony

Objective]To study annual growth of different cultivar groups.Method]We selected four cultivar groups of peony (Zhongyuan cultivar group,Xibei ciltivar group,Japanese cultivar group,Europe and America cultivar group) in Luoyang as materials to study their annual growth,annual actual remaining amount and actual remaining rate.Result] The order of average annual growth was Europe and America cultivar group>Xibei cultivar group>Japanese cultivar group > Zhongyuan cultivar group.The order of average annual actual remaining amount was Xibei cultivar group> Japanese cultivar group> Europe and America cultivar group> Zhongyuan cultivar group.The order of the average actual remaining rate was Xibei cultivar group> Japanese cultivar group>Zhongyuan cultivar group> Europe and America cultivar group,the peony of Xibei cultivar group performanced outstanding.Conclusion]The study provided a theoretical basis for the development of rational cultivation management technology and the breeding of new varieties of peony.
