Abstract
The correlation between chemical components of shoot and leaf of Camellia oleifera and elevations were discussed, to provide theoretical basis for taking effective cultivation measures to promote the cold resistance of C. oleifera in the future “Northward Movement of C. oleifera”. The ratio of bound water to free water of the leaf, as well as the contents of holocellulose, cellulose, lignin and benzene-ethanol extracts were determined. The results showed that: In different elevations, the ratio of bound water to free water of the leaf varied from 0.11-0.22, the contents of holocellulose, cellulose, lignin and benzene-ethanol extracts varied from 25.08%-62.72%, 7.72%-36.61%, 11.80%-30.29% and 7.66%-8.57% respectively. In the same elevation, the content of benzene-ethanol extracts of leaf was higher than that of shoot, and the contents of other materials were quite the contrary. The elevation was positively correlated with the ratio of bound water to free water and the contents of holocellulose, cellulose, lignin and benzene-ethanol extracs. The chemical components of shoot and leaf represented extremely significant difference (p
