【摘要】 通过对中原、西北及日本牡丹品种群在不同光照强度下的花量、花枝数、花径和1年生花枝长度的调查,分析了不同光照强度对牡丹生长发育的影响。结果表明:3个品种群的相对花量和相对光强显著相关;中原和西北品种的花径与相对光强显著相关,日本品种群中两者相关不显著;日本和西北品种花枝长度与相对光强相关极显著,中原品种群的花枝长度与相对光强相关不显著;中原、西北和日本品种群最适宜的相对光强范围分别为30%~75%、60%~100%和27%~50%。

【Abstract】 An experiment was conducted to study the effect of light intensity on number of flowers,flower diameter and twig length of Chinese Zhongyuan cultivar,Chinese Xibei cultivar and Japanese cultivar of tree peony.Results showed that the relative number of flowers of three cultivars had significant correlation with relative light intensity,and the flower diameters of Chinese Zhongyuan and Xibei cultivars were also significantly correlative with relative light intensity.The flower diameter of Japanese cultivar had insignificant correlation with relative light intensity.The twig lengths of Japanese and Chinese Xibei cultivars had extremely significant correlation with relative light intensity,while the twig length of Zhongyuan cultivar had insignificant correlation with relative light intensity.The optimal light intensities for Chinese Zhongyuan,Xibei cultivars and Japanese cultivars were 30%~75%,60%~100% and 27%~50% respectively.
