摘　　要：对深圳梧桐山风景区7个山茶品种的形态指标、生理指标进行定量分析。结果表明:7个山茶品种的成活率都较高;‘红露珍’和‘帕克斯先生’的夏梢生长量最大;‘红露珍’的可溶性糖含量最高,为26.51 mg·g-1;‘玫红茶梅’的可溶性蛋白含量最高,为15.32 mg·g-1;‘帕克斯先生’的SOD酶活性较高,为86.80 U·g-1;‘玫红茶梅’的POD活性较高,达到417.6 U·g-1min-1;‘玫红茶梅’的丙二醛含量最低,为0.14μmol·g-1;‘帕克斯先生’的实际光化学效率、光化学猝灭系数和电子传递速率较大。应用多维空间坐标综合评定方法,初步选定‘帕克斯先生’是最优的山茶品种。In this study, the morphological and physiological characteristics of seven cuhivars of Camellia japonica, ＇ Dr Clifford Parks ＇ , ＇ Camellia sasanqua＇ , ＇ Hongluzhen ＇ , ＇ High Fragrance ＇ , ＇ Songzi ＇ , ＇ Massee Lane ＇ and ＇ Margaret Davis＇ , were investigated. Results showed that all the eultivars had high survival rates. ＇ Hongluzhen＇ and ＇ Dr Clifford Parks＇ had relatively faster summer shoot growth. ‘ Hongluzhen＇ had the highest soluble sugar content of 26.51 mg· g-1 while ‘ Camellia Sasanqua＇ had the highest soluble protein content of 15.32 mg· g-1‘ Dr Clifford Parks＇ possessed the highest SOD activity （86.80 U·g-1） while ＇Camellia Sasanqua＇ had the highest POD activity （417.6 U·g-I min-I） among the cultivars studied. ‘Camellia Sasanqua＇ had lower M DA content than others. ‘Dr Clifford Parks＇ had the highest φPSH, qP, ETR. Based on the above results, ＇Dr Clifford Parks＇ was considered as best cultivar adapting to the Mount Wutong National Park in Shenzhen by the multi-dimensional coordinate-synthetic-evaluation method.
