摘要： Camellia oleifera Abel originates from China and is high healthy effect food oil species. It is also a high additional plant in southern China and can help to keep some people of mountain area out of poverty. In recent years, climate change has been abnormal frequently. Abnormal low temperature in winter and late spring coldness may cause the hard hit to C. oleifera farmers. Freezing injury can be caused by sudden decreases in temperature in winter. However, C. oleifera varieties differ in their hardiness to low temperatures. The paper investigated cold-resistance mechanisms by determining and analyzing the morphological, physiological and biochemical characteristics of C. oleifera from eastern, western and southern Anhui, respectively. Sensitivity to low temperature was assessed via the number of leaves in spring shoots, leaf thickness, the activities of protective enzymes such as CAT, POD and SOD, and the inclusion contents of WSS, FPro, MDA, benzene-alcohol extracts and lignin. The results showed that C. oleifera varieties had different physiological and biochemical, and morphological responses to low winter temperatures. In different regions, the number of leaves, leaf thickness, WSS content, FPro content and MDA content varied from 5.2-7.8, 398.79 mu m-465.27 mu m, 23.41mg/g-24.74mg/g, 41.86 mu g/g-44.18 mu g/g and 10.08 mu mol/g-14.51 mu mol/g, respectively. The varieties from eastern Anhui, the leaf thickness were thicker. Meanwhile, the protective enzyme activities and inclusion contents were relatively higher. The protective enzyme activities and chemical components contents such as benzene-alcohol extract and lignin represented significantly difference (p<0.05) among three regions. In the future, for the abnormal low temperature in winter, a serious of cultivation measures such as improving the contents of WSS, FPro, benzene-alcohol extract and lignin, were taken to enhance the cold resistance of C. oleifera. The result broadens the understanding of cold-resistance mechanisms in C. oleifera.
