| 摘 要： | 以玉米抗、感纹枯病的4个品种为材料，研究了生物型种衣剂ZSB对玉米纹枯病的防效，经种衣剂处理后再接种玉米纹枯病病原菌R. solani主要寄主防御反应酶系POD、PPO和PAL活性的动态变化。结果表明生物性种衣剂ZSB处理后能在一定程度上控制纹枯病的危害，对抗病品种瓦试13和沈试28防效为39%和49.7%，高于对感病品种沈试29和掖单13的防效。4个玉米品种经种衣剂处理后再接种玉米纹枯病病原菌R. solani主要寄主防御反应酶系POD和PPO活性高峰出现的早，且高于单独接种的。但是种衣剂处理后寄主PAL活性没有明显差异。 |

| Abstract: | Dynamic the effective function of biological seed coating ZSB and changes of in active of peroxideases (POD),polyphenoloxides (PPO) and phenylalantine ammonia lyases (PAL) in two resistant cultivars and two susceptible ones of maize after inoculating Rhizoctonia solani were studied in the paper.The results showed that ZSB had an effective function to control sheath blight of four cultivars of maize.The effective function to Washi13 and Shenshi28 was 39% and 49.7%,which was higher than that of Yedan13 and Shenshi29.It was more likely that ZSB control effect was devoted by its induction to PPO and POD in host prior to and higher than inoculation with R.solani.It should be noted that some special phenomenon such as still no significant increase of PAL needed to be further investigated. |
