在调查和研究我区麦类条锈病流行规律的过程中,我们于1978年冬季,在拉萨自然条件下进行了定点观察及室内麦类条锈菌孢子发芽测定。于当年九月在区农科所三号地定二十个点进行了定期观察,发病部位盖为第一、二片真叶,其严重度为5%;普遍率为3%,均未发现再侵染现象。至当年十月中旬开始,青稞地上部开始部分枯黄,因病叶表皮破裂,蒸腾量增加,抗寒抗旱的能力明显下降, In the course of investigating and studying the epidemic rule of wheat stripe rust in our district, we carried out the fixed-point observation and the spore germination of indoor wheat stripe rust in the winter of 1978 under the natural conditions of Lhasa. In September of that year, there were 20 points in the No.3 Agricultural Science Station regularly observed. The disease sites covered the first and second true leaves with a severity of 5% and a prevalence rate of 3% Re-infection phenomenon. By the middle of October of that year, the upper part of the barley began to turn yellow partly. Due to the broken epidermis of the diseased leaves, the amount of transpiration increased, and the ability of drought resistance and drought resistance decreased obviously.
