Résumé :
|
The injury on the lucerne seedlingscaused by Lygus rugulipennis manifests itself by witling and drying of plants. Provided the plants survive the suction of bugs, they show a retardated growth. Tests of lucerne resistance to Lygus rugulipennis revealed that Czechoslovak varieties of the lucerne possess different degrees of sensivity to the injury. The less injury occurs in the local variety >, the most in the variety >. A number of the bugs dies always in the course of the experiment. When testing the plant resistance it is necessary to complete daily the bugs, otherwise the results are not reliable.
