Induced quiescence in Heterorhabditis bacteriophora varies among green pea cultivars. Induced EPN quiescence was significantly influenced by the cultivar the root-cap exudates were collected from (grey bars). Three cultivars induced quiescence close or equal to 100% whereas some barely reached 30%, but were still different from the percentage of inactive nematodes recorded in water (white bar). One cultivar (Kelvin Sprinter) was not different from water. Letters indicate statistical differences. Bars represent SEM.
