摘要: 以东莞现栽14个荔枝品种为研究对象,对其比叶面积、叶干物质含量和叶片SPAD值等特征进行研究。结果表明,果皮龟裂片尖突、平坦、隆起等3种类型中,尖突类型的3个荔枝品种的比叶面积显著大于平坦类型的2个品种;隆起类型的9个荔枝品种的比叶面积大小不一,其中5个品种的比叶面积大于平坦类型的‘黑叶’品种,另外4个品种的比叶面积小于‘黑叶’。14个荔枝品种中,除了‘黑叶’外,其余13个品种的比叶面积和叶干物质含量均呈负相关关系;‘水晶球’和‘大丁香’的比叶面积和叶片SPAD值间呈正相关关系,其余12个品种的比叶面积和叶片SPAD值间均为负相关关系。

关键词: 荔枝, 比叶面积, 叶片干物质含量, 叶片SPAD值

Abstract: The leaf traits, such as specific leaf area, leaf dry matter content and leaf SPAD value of fourteen Litchi chinensis cultivars were analyzed in this study. The results showed that specific leaf area of three L. chinensis cultivars with apiculate peel were greater than that of two cultivars with flat peel. Among nine cultivars with ridge peel, specific leaf area of five cultivars was greater than that of ‘Heiye’, a cultivar with flat peel, and specific leaf area of four other cultivars was smaller than that of ‘Heiye’. Of all the Litchi chinensis cultivars, speci?c leaf area of thirteen cultivars had positive correlation with leaf dry matter content except ‘Heiye’. The correlation between speci?c leaf area and leaf SPAD value was positive for ‘Shuijingqiu’ and ‘Dadingxiang’, but negative for the other twelve cultivars.

Key words: Litchi chinensis, specific leaf area, leaf dry matter content, leaf SPAD value
