摘要
选用果蔗(Saccharum officinarum L.)14个品种,用典范相关分析法研究不同生育期叶片生理生化指标对果蔗品质性状的影响。结果表明:分蘖期类胡萝卜素含量与蔗茎蔗糖含量,可溶性总糖含量与蔗茎含水率,可溶性总糖含量与蔗汁还原糖含量均呈正相关;伸长初期叶绿素含量、CAT活性与蔗茎蔗糖含量,可溶性蛋白质含量与蔗茎纤维含量均呈正相关;伸长盛期Mg2+-ATP酶活性与蔗茎纤维含量,可溶性总糖含量与蔗茎蔗糖含量呈正相关,C/N与蔗茎含水率呈负相关;成熟期类胡萝卜素含量与蔗茎蔗糖含量呈正相关,可溶性总糖含量与蔗汁还原糖含量呈负相关。
The relationship between ten physiological and chemical indexes in leaves of sugarcane （Saccharum officblarum L.） and five quality characters of stalks were conducted by using method of canonical correlation analysis. The results indicated that at tillering stage, there were positive correlations between content of carotenoid and sucrose content in cane, content of total soluble sugar and water content in cane, content of total soluble sugar and reducing sugar in juice, respectively. At early elongating stage, there were positive correlations between contents of chlorophyll, activity of catalase and sucrose contents in cane, content of soluble protein and content of cane fibre, respectively. At middle elongating stage, there were positive correlations between activity of Mg^2＋ - ATPase and cane fibre, content of soluble sugar and sucrose content in cane, respectively, but there was negative correlation between carbon-nitrogen ratio （C/N） and water content in cane. At the maturing stage, there was positive correlation between content of carotenoid and sucrose content in cane, and negative correlation between content of soluble sugar and reducing sugar in juice.
