【摘要】 对四川地区有代表性的52份野生狗牙根材料的11项数量性状进行了分析,结果表明:野生狗牙根表现出丰富的形态多样性,变异系数在4%～30.92%之间,平均变异系数达17.28%;外部性状间有一部分存在着显著或极显著的相关性,相关系数最大达到0.768;通过聚类分析,四川狗牙根被分为高丛型和矮丛型两类,其中,矮丛型又分为长茎宽叶型、长叶型和短叶型,高丛型分为长茎短叶型、长茎宽叶型和长叶型三类。更多还原

【Abstract】 Data of eleven quantitative characters of fifty-two representative wilding-bermudagrass in Sichuan were analyzed to determine the morphological characters’ diversity. The results were as follows: Diversity in morphology of wilding-bermudagrass in Sichuan were discovered, the variant coefficient was between 4% and 30.92%,the average of variant coefficient was 17.28%;There existed significant correlations among some of morphological characters of bermudagrass in Sichuan, the maximal correlations coefficient was 0.768; Bermudagrass germplasm resources in Sichuan can be divided into two morphological types based on the eleven characters,that is, dwarf type and tall type.更多还原
