Abstract: Numerical classifications are made for masson pine communities in warm secondarv coniferous forest at Nansan mountain. Fuzzy aggregation analysis is applied,and six asxoclation groups and ten associations are classified.The results of classification coincide with actual conditions of vegetation resources.

Key words: hypoxia stress, γ-aminobutyric acid, melon, polyamine metabolism.
