Abstract:

In this study, the morphological and physiological characteristics of seven cultivars of Camellia japonica, ‘Dr Clifford Parks', ‘Camellia sasanqua', 'Hongluzhen', ‘High Fragrance', ‘Songzi', ‘Massee Lane' and ‘Margaret Davis', were investigated. Results showed that all the cultivars 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-1min-1) among the cultivars studied. ‘Camellia Sasanqua' had lower MDA content than others.‘Dr Clifford Parks' had the highest ΦPSⅡ, 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.

Key words: Camellia japonica cultivars, morphological characteristics, physiological characteristics, multidimensional coordinate-synthetic-evaluation way
