摘　　要：All these hosts became less susceptible as the plants matures. Ascospores were unable to infect linseedleaves in the absence of an exogenous nutnent base. Even though sucrose could be used as an exogenous nutrient to stimulate the ascospores to germinate, the ascospores subsequently failed to infect undamaged linseed leaves. Linseed flowe petals were an effective nutrient base which stimulated ascospores to genninate as well as to infect undamaged linseed leaves.All these hosts became less susceptible as the plants matures.
