使用降雨模拟器研究了地面覆盖、植物冠层密度和降雨强度对尖头炭疽病飞溅扩散的影响。在一项实验中，通过在受遮蔽的重力采样器中收集带有分生孢子的飞溅液滴来评估三种地面覆盖物（土壤、稻草和塑料）和两种降雨强度（15 和 30 毫米/小时），该采样器由培养皿和 C. acutatum 选择性培养基组成。地面覆盖物的特征是随机粗糙度，即表面高程的标准偏差。带有孢子病斑的受感染水果聚集在地面上作为接种源（...）
Effects of ground cover, plant canopy density, and rain intensity on the splash dispersal of Colletotrichum acutatum were studied using a rain simulator. In one experiment, three ground covers (soil, straw, and plastic) and two rain intensities (15 and 30 mm/hr) were evaluated by collecting splash droplets with conidia in sheltered gravity samplers consisting of petri plates with a selective medium for C. acutatum. Ground covers were characterized by random roughness, the standard deviation of surface elevation. Infected fruits with sporulating lesions were clustered on the ground to serve as the inoculum source (...)
