摘　　要：选取广东省佛山林业科学研究所的山茶园中10种茶花为研究对象,对其叶片养分以及比叶面积进行测定分析。结果表明:10种茶花的叶片特征存在差异,茶花叶片中N、P、K、Ca、Mg含量范围分别为9.46~15.55、0.53~1.37、5.03~11.18、3.37~18.62、0.66~1.86 g·kg-1;SLA的范围为35.34~65.57 cm2·g-1;茶花叶片中N/P范围为9.61~17.85、N/K范围为1.18~1.99、K/P范围为5.10~9.92。主成分分析表明:茶花叶片特征排序为皇家天鹅绒>杰作>海泡>皇家天鹅绒>黄绣球>赛桃红>甜香水>烈香>恒丰9号>茶梅>张氏红山茶。The leaves nutrient content and specific leaf area of ten camellia species were studied in forestry science institude, Foshan, Guangdong. Results showed that there were differences in leaf nutrient content among the ten camellia species, the contents of nitrogen, phosphorus, kaliurn, calcium and magnesium ranged from 9.46 to 15.55, 0.53 to 1.37, 5.03 to 11.18, 3.37 to 18.62 and 0.66 to 1.86 cm2·g-1, and ratios of N/P, N/K and K/P were 9.61-17.85, 1.18-1.99 and 5.10- 9.92; respectively, and the specific leaf area ranged from 35.34 to 65.57 cm2·g-1. Principal components analysis indicated that the order of leaf characteristics decreased in the order of C. japonica ＇Huangjia Tiane rong＇ 〉 C. remek-delo travijata 〉 C. japonica ＇Hai Pao＇ 〉 C. japonica ＇Huang Xiuqiu＇ 〉 C. reticulata ＇Saitao Hong＇ 〉 C. scentuous 〉 C. japonica ＇High Fragrance＇ 〉 C. reticulata ＇Hengfeng 9 hao＇ 〉 C. sasanqu 〉 C. changii.
