摘要：

Regression analyses of the effect of cereal cyst eelworm (Heterodera avenae Woll.) on spring‐sown wheat, barley and oats in two fields during 1963 and 1964 showed that the eelworm attack had reduced the yields of all three cereals in both years. For every ten eggs of H. avenae per g of soil before cropPl.ng there was an approximate loss of 3 cwt/acre (376 kg/ha) of oats and 1·5 cwt/acre (188 kg/ha) of wheat, but only 0·6 cwt/acre (75 kg/ha) of barley. Thus the loss of oats was about twice that of wheat and five times that of barley. These results are compared with those of other workers some of whom used resistant cultivars or soil fumigants.
