Abstract

Gall size and rates of ethylene production by various hosts infected with Meloidogyne javanica and by excised tomato root cultures infected with M. javanica or M. hapla were measured. Infection with M. javanica increased the rate of ethylene production in dicotyledonous plants (cabbage, pea, carrot, cucumber, carnation, and tomato), but not in infected monocotyledonous plants (corn, wheat, and onion). Nematode infection induced large galls on roots of dicotyledonous, but not monocotyledonous, plants. Excised tomato roots in culture infected with M. javanica produced ethylene at high rates and formed large galls, whereas roots infected with M. hapla produced ethylene at low rates and induced smaller galls. Key words: Meloidogyne javanica, M. hapla, monocotyledon, dicotyledon, gall size.
