摘　　要：本文以锦屏藤(Cissus sicyoides‘Ovata’)为材料,对在重庆地区不同生长环境下的锦屏藤进行了形态观察,并依据叶长、叶宽、叶柄等7个性状进行了形态差异分析;利用灰色关联分析方法对其进行夏、秋季的观赏性评价。结果表明,在本试验条件下,锦屏藤植株无死亡现象,在不同生长环境下形态特征表现显著差异(P<0.05);通过灰色关联分析,在夏秋季节不同生长环境下,锦屏藤观赏价值与理想品种的关联度最低为0.4149,最高达到0.9560;在生长期内,锦屏藤冬季休眠,春季发芽,夏秋季观赏价值较高,能够适应重庆地区,并且其观赏价值仍有提升空间。The 7 characters of Cissus sicyoides ＇ Ovata＇ such as leaf length, leaf widths and petioles and etc. in different growth conditions were used to analyze the difference of morphology and ornamental value was evaluated by using the grey relation analysis method for summer and fall. The results showed that Cissus sicyoides ＇ Ovata＇ had no dead phenomenon in different growth conditions, and the morphological characteristics had significant difference （P 〈 0.05 ）. Through the grey relational analysis, the con＇elation between Cissus sicyoide ＇ Ovata＇ ornamental value and ideal varieties had the lowest（0.5190） and a maximum（0. 9560）, indicating that Cissus sicyoide ＇ Ovata＇ could adapt Chongqing, and ornamental value could be promoted.
