Abstract
Abstract The root-knot nematode M. javanica did not develop on two-month-old peach seedlings of the resistant cvs. Nemaguard and Okinawa, even when they were copiously inoculated with egg masses of the nematode, under conditions in which seedlings of the susceptible ‘Baladi’ supported a considerable nematode population. However, when “resistant” seedlings were wick-fed with kinetin or NAA, the development of a normal nematode population became possible. The 2 substances produced synergistic stimulating effects on nematode development; they also increased the nematode population in the susceptible cultivar. The effect on the plant of NAA supplied by this technique was expressed in increased root growth and reduced top growth. It caused the development of swelled, non-suberized branch roots which became the favored habitat of the nematodes. Kinetin at the concentrations used, on the other hand, had no visible effect on the growth of the seedlings. The possible role of kinetin and NAA in altering the host-parasite relationship is discussed.
