抑制剂Ａ与Ｂ分别设４种浓度，对水稻进行了浸种发芽试验。结果表明，抑制剂Ａ能使种子萌动，但不能生长；抑制剂Ｂ能抑制种子完全不萌动。但一旦去抑制以后，则不能再抑制种子的生长。用３．５－二硝基水扬酸法测定酶活性表明，抑制剂Ａ的淀粉酶活性变化与对照相似，α－淀粉酶与β－淀粉酶比对照略低；抑制剂Ｂ的淀粉酶活性变化与对照差异显著，处理种子淀粉酶活性１０天中均处于极低水平。抑制剂Ａ以抑制剂种子萌发中后续酶合成为主，从而抑制生长；抑制剂Ｂ以抑制种子内存酶激活为主，从而抑制种子萌发
Inhibitors A and B were set at four concentrations, soaking rice germination test. The results showed that inhibitor A could germinate seeds, but could not grow; inhibitor B could inhibit the seeds from germinating completely. However, once detoxified, the growth of the seed can no longer be inhibited. The enzymatic activity measured by 3.5-dinitro salicylic acid method showed that the change of amylase activity of inhibitor A was similar to that of the control, the α-amylase and β-amylase were slightly lower than that of the control; the amylase activity of inhibitor B The difference was significant with the control, and the seed amylase activity was extremely low in 10 days. Inhibitor A inhibits seed germination by subsequent enzymatic synthesis and inhibits growth. Inhibitor B inhibits seed enzyme activity and inhibits seed germination
