摘要
小麦条锈病由小麦条锈菌（Puccinia striiformis Westend．）引起，该病害发生范围广、流行频率高、危害损失重。小麦条锈菌侵染与繁殖均需要较低温度，过去研究表明，条锈菌在夏季最热旬均温23℃以下地区才能越夏。近年调查研究发现，
The temperature-sensitivity of 126 isolates of Puccinia striiformis Westend. （Pst） sampled from different regions and periods was tested. The results showed that there existed a great ET50 （ median effect temperature, which represents the temperature that is required to obtain 50% of the maximum effect ） difference in Pst population tested, the average ET50 was 24.01℃ with the highest of 27.01℃ and the lowest of 18.46℃. On the whole, the Pst population sampled from warmer,lower elevation or latitude regions showed significant adaptation to warmer temperature.
