六种路易斯安娜鸢尾冬季生长状况及观赏性比较

Comparison of growth status and ornamental characteristics of six kinds of Iris hybrids‘Louisiana’in winter

为了评价路易斯安娜鸢尾新品种的生态适应性,本研究对新引进的noble moment、colorific、sinfonietta、sea knight、pastiche、forsted moonbeam等六个路易斯安娜鸢尾新品种的冬季生长状况和观赏性进行了比较,检测分析了叶片叶绿素含量、叶片氮含量、叶片含水量等生理指标和叶片数目、叶片厚度、株高、叶面积等形态指标。六个品种路易斯安娜鸢尾均能在河南郑州地区生长,但不同品种在冬季生长状况和观赏性等方面的表现不同,生长状况的综合表现为:noble moment>colorific>sea knight=pastiche>sinfonietta>forsted moonbeam,观赏性的综合表现为:noble moment>sea knight=pastiche>sinfonietta>forsted moonbeam>colorific。

In order to evaluate the ecological adaptability of new varieties of Iris hybrids‘Louisiana’,this study compared the growth status and ornamental value of six newly introduced noble moment,colorific,sinfonietta,sea knight,pastiche and forsted moonbeam.Through the detection and analysis of physiological indexes such as chlorophyll content,leaf nitrogen content,leaf water content,and morphological indexes such as leaf number,leaf thickness,plant height and leaf area.All six varieties of Louisiana iris could grow in Zhengzhou of Henan Province,but the growth status and ornamental performance of different varieties were different in winter.The comprehensive expression of growth condition is as follows:noble moment>colorific>sea knight=pastiche>sinfonietta>forsted moonbeam.The comprehensive expression of ornamental value is as follows:noble moment>sea knight=pastiche>sinfonietta>forsted moonbeam>colorific.
