Abstract:
The variation of the content of soluble sugar, protein and total phenolics in leaves of 18 clones of Populus deltoides at seedling stage was measured, and the relationship with the clones' resistance to Tetra lobuliferawas analyzed. The results showed that there was significant difference in the contents of soluble sugar, protein and total phenolics in the leaves among the clones. Correlation analysis indicated that the contents of soluble sugar and total phenolics in leaves of P. deltoides were significantly correlated with the resistance to T. lobulifera, while the content of protein in the leaves was not correlated with the resistance. The clones with higher content of total phenolics in the leaves were mite resistant, conversely were mite susceptible.
Key words: Populus deltoides, Tetra lobulifera, chemical substances, resistance to mite
