Abstract: 【Objective】To analyse the impact of various amino-oligosaccharide treatments on mung bean growth.【Methods】The effects of amino-oligosaccharides on the activities of the mung bean defense enzymes(SOD,POD,and PPO),as well as SPAD value and yield,were compared and analyzed using an orthogonal experiment with three factors and five levels,including seed soaking concentration(A),spraying concentration(B),and spraying period(C).【Results】In comparison to the other two treatments,the effect of seed soaking concentration(A)on SOD activity,POD activity,and SPAD value of mung bean leaves was higher. Spraying concentration(B)had a marginally higher impact than the other two treatments on the PPO activity of mung bean leaves. Under different levels of each factor,seed soaking concentration A3 had the highest yield of 2 050.83 kg/hm2,spraying concentration B4 had the highest yield of 1 989.17 kg/hm2 and spraying period C3 had the highest yield of 1 931.67 kg/hm2.【Conclusion】Among the diffrent treatments,seed soaking concentration had the highest effect on the yield of mung bean,followed by the spraying concentration and spraying period. The optimal treatment combination for yield was A3B4C3,with seed soaking concentration at 0.4 g/100 mL,spraying concentration at 1.8 g/L,and spraying twice in the full flowering stage.
