摘要：山茶花是我国著名的木本花卉，在园林上主要用作地栽或者盆栽供观赏，少数品种也可用作盆景或者切花。花可入药，种子可以榨油食用，木材可供雕刻之用，总之山茶全身是宝。
In this paper four species, C. chekiangoleosa, C. grijsi, C. octopetala and C. semiserrata with different cold hardiness were used to determine the electrolyte leakage and MDA content in their leaves after treated with different low temperatures, 1.5℃, - 6.5 ℃, - 16℃, - 22 ℃. Results showed that the plasma membrane permeability became much obviously with the fall of temperature. When the temperature is - 16℃ ,the electrolyte leakage of C. chekiangoleosa, C. grijsi, C. octopetala increased sharply to 1.89,1.33, and 1.64 times more than that of the - 6.5℃. The electrolyte leakage of C. semiserrata was the most at - 6.5℃ ,which was 87.1% more than that of the 1.5℃. MDA content changed regularly with the fall of temperature, raised at first and then declined. When the temperature is - 6.5℃, MDA content of C. semiserrata was the most ,which was 2.42 times of the control ;And when the temperature is - 16℃, MDA content of C. chekiangoleosa, C. grijsi, C. octopetala were the highest and were 75% , 1.39 times and 1.02 times respectively more than that of the control.
