玉米南方锈病由玉米多堆柄锈菌(Puccinia polysora Underw.)引起,主要分布在热带和亚热带地区,但随着全球气候变暖,其发生范围不断扩大,对玉米生产的影响也随之扩大。对于该病害发病温度范围的测定有助于病害发生范围的区划和病害预防工作的进行。试验将多堆柄锈菌接种到供试玉米材料‘郑单958’上,置于不同温度下的光照培养箱中培养并观察发病情况,从而确定出玉米南方锈病的发病温度范围以及发病最适温度范围。试验结果表明：玉米南方锈病的发病温度范围为15~31℃,最适温度范围为24~27℃。

Southern corn rust,caused by Puccinia polysora Underw.,mainly distributes around tropical and sub-tropical areas.It is getting more and more wide-spread along with the global warming and its influence on corn production is getting bigger and bigger.Determination of temperature required by southern corn rust can be very useful for mapping its distribution and preventing the disease.By inoculating and incubating P .polysora on the corn variety ‘Zhengdan 958’under different temperatures in illumination incubators,we found that the tempera-ture required by southern corn rust was 1 5-31 ℃,and the optimal temperature was 24-27 ℃.
