江南牡丹引种洛阳生物学特性及物候期研究

[目的]掌握江南牡丹在洛阳地区的生长状况.[方法]2012 ～2014年对从安徽宁国引进的6个能够在洛阳地区生长开花的江南牡丹品种进行生物学特性及物候期观察研究.[结果]不同江南牡丹品种在洛阳地区的物候期存在一定的差异,其花期主要集中在4月上中旬,整体花期15d左右.不同品种茎叶生长情况和开花情况不一致,花色基本保持品种原有色泽,但花型却存在不同程度的退化现象.[结论]该研究可为制定江南牡丹在洛阳地区合理的栽培技术方案、花期预测等提供理论依据.

Biological Characteristics and Phenological Period of Jiangnan Peony in Luoyang

[Objective] To study growth conditions of Jiangnan Peony in Luoyang.[Method] From 2012 to 2014,4 Jiangnan Peony varieties from Ningguo,Anhui Province able to grow and blossom in Luoyang City were studied to figure out their biological characteristics and phonological periods.[Result] Phenological periods of these varieties in Luoyang area varied slightly,and their flowering season concentrated in the early and middle April,and the flower season lasted for 15 days or so.Different varieties also showed differences in stem and leaf growth,and flowering conditions,flower color basically maintained original luster of the varieties,but flower shape showed degradation to different extents.[Conclusion] This study provides theoretical basis for making reasonable cultivation schemes and flower season forecast of Jiangnan peony varieties in Luoyang City.
