本所从1975年以来,对子囊孢子飞散数量与小麦赤霉病病穗率的相关性进行了观察和研究。发现3月中旬至4月中旬各旬的子囊孢子捕捉数,与当年的病穗率均具有不同程度的正相关,尤其是3月下旬子囊孢子捕捉数与病穗率相关极显著。
Since 1975, our institute has observed and studied the correlation between the number of ascospores scattered and the panicle head blight rate. It was found that the number of ascospore capture in each period from mid-March to mid-April was positively correlated with the prevalence of disease-specific panicles in the current year. In particular, the number of ascospore capture in late March was significantly correlated with the incidence of panicle disease.
