摘要：
The effect of Heterodera avenae attacking winter wheat cv. Talento was studied under controlled conditions. Growth of plants at two levels of infestation with newly-formed cysts (low, 15 cysts per pot and moderate, 25 cysts per pot) was compared with that in an uninfested control. Growth stages in decimal code and yield parameters were recorded. The multiplication rate of the nematode was greater in plants infested with a moderate density of cysts. Both the low and the moderate density of cysts resulted in a delay of plant development and reduced kernel weight and 100-kernel weight, revealing the negative influence of the nematode throughout crop development.
