环境条件对棉花轮纹斑病菌分生孢子萌发的影响
Effect of Environment Conditions on Conidia Germination of Cotton Alternaria Leaf Spot
摘要
Abstract
The effect of nutrition, illumination, temperature, humidity on conidia germination of cotton alternaria leaf spot was studied. The results showed that the pathogen conidia has different germination capacity in different conditions: conidia in the SDAY culture solution has the highest germination rate; dark treatment is more conducive to conidia germination; the optimum temperature is 30℃; for the relative humidity, the higher the better, the optimum humidity is in the water drops; slurry of differ-ent varieties cotton leaves had a significant effect on the conidia germination rate, and slurry of Ning 4-14 and Ken 62 is more conducive to conidia germination.关键词
