氨基寡糖素对绿豆叶片防御酶活性和产量的影响
Effects of amino-oligosaccharin on leaf defense enzyme activity and yield of mung bean
【摘要】 【目的】揭示氨基寡糖素不同处理对绿豆生长的影响。【方法】采用三因素五水平正交试验设计,设浸种浓度(A)、喷施浓度(B)和喷施时期(C)3个因素,每个因素设5个水平,比较分析氨基寡糖素不同处理对绿豆叶片防御酶(SOD、POD、PPO)活性、SPAD值和产量的影响。【结果】浸种浓度(A)对绿豆叶片SOD活性、POD活性和SPAD值的影响高于其他2个因素处理,喷施浓度(B)对绿豆叶片PPO活性的影响略高于其他2个因素处理。每个因素的不同水平下,浸种浓度A3对应的绿豆产量最高,为2 050.83 kg/hm~2;喷施浓度B4对应的绿豆产量最高,为1 989.17 kg/hm~2;喷施时期C3对应的绿豆产量最高,为1 931.67 kg/hm~2。【结论】氨基寡糖素不同处理对绿豆产量的影响顺序为浸种浓度>喷施浓度>喷施时期,产量最优处理组合为A3B4C3,即浸种浓度为0.4 g/100 m L、喷施浓度为1.8 g/L、喷施时期为盛花期喷施2次。
【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 SPADvalue 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/hm~2,spraying concentration B4 had the highest yield of 1 989.17 kg/hm~2 and spraying period C3 had the highest yield of1 931.67 kg/hm~2.【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 m L,spraying concentration at 1.8 g/L,and spraying twice in the full flowering stage.
