采用Luminol的化学发光法测定了叶肉细胞在毒素作用下活性氧的变化动态 ,结果表明 ,HT—毒素胁迫下玉米叶片悬浮细胞的活性氧代谢发生明显改变。某些阳性离子、化合物和处理体系的温度对玉米叶片细胞的活性氧代谢影响很大。此外 ,外源加入一定浓度的H2 O2 对玉米大斑病菌、玉米小斑病菌和玉米弯孢霉的菌丝生长、分生孢子的产生和萌发及毒素的产生等都有明显的抑制作用或影响
Luminol chemiluminescence method was used to determine the dynamic changes of reactive oxygen species in mesophyll cells under the action of toxins. The results showed that active oxygen metabolism of suspended cells in corn leaves changed significantly under HT-toxin stress. The temperature of certain positive ions, compounds and treatment systems have a great effect on the reactive oxygen metabolism of maize leaf cells. In addition, the addition of a certain concentration of H 2 O 2 significantly inhibited or influenced the mycelium growth, conidia generation and germination, and toxin production of S. turcica, P. solani and C. coronatum
