| 摘 要： | 对吉林省玉米锈病发生规律的若干问题进行了研究,明确了以下问题:玉米植株在生育后期对锈菌的侵染抵抗能力要明显强于生育前期;玉米不同叶位的叶片抗侵染能力有明显差异,老叶抗病性强于新叶;增施N肥和P肥,可削弱玉米对锈病的抵抗能力,但增施K肥可增强玉米对锈病的抵抗能力;玉米品种对锈病的抗性差异显著,自交系2L637、2L725、单交种铁15、辽单33、丹玉3、铁12抗性较好。

| Abstract: | Some problems about corn common rust in Jilin province were studied,the results showed that:late stagewere more resistant than early stage of corn ;Different leaves in position had different resistance,younger leaaves were more susceptible than mature leaves.High nitrogen and phosphate made the plant more susceptible,but high potassium tends to decrease incidence;Resistance were different among cultivars and inbred lines,inbred lines2L637,2L725 and cultivars Tie15,Liaodan33,Danyu3,Tie12,etc.were more resistant than others. |
