摘要：
The objective of this article is to study the effect of 5-aminolevulinic acid (ALA) and enhanced chlorophyll content, antioxidative enzymes and photosynthesis rate by foliar application of ALA. We evaluated three concentrations (control-distilled water, T1-50 mg l(-1), T2-150 mg l(-1), T3-250 mg l(-1)) of ALA and seven cultivars, "Sanchidaye" (Sa-1), "Lichuandasuomian" (Li-1), "Aijiaohuang" (Ai-1), "Qingyou" No. 4 (Qi-1), "Aikang" No. 5 (Ak-1), "Hanxiao" (Ha-1) and "Shulv" (Sl-1). "Ak-1" showed strongest response of POD (peroxidase) enzyme activity (0.4 U g(-1) min(-1)) in 250 mg l(-1) ALA solution. The highest CAT (catalase) activity (0.8 U g(-1) min(-1)) after administration of 250 mg l(-1) ALA was observed in "Li-1". Meanwhile, highest (1.42 mg l(-1)) total chlorophyll content was also observed in "Ak-1", when leaves were treated in 50 mg l(-1) ALA, "Li-1" and "Ai-1" showed strongest response of specific activity of superoxide dismutase (SOD) in 50 mg l(-1) and 50 mg l(-1) ALA. Two hundred and fifty milligram per milliliter of ALA-treatment significantly improved the net photosynthetic rate.
