Interrelationships between Ethylene Production, Gall Formation, and Root-knot Nematode Development in Tomato Plants Infected with Meloidogyne javanica.
Ethylene production was determined in excised tomato (Lycopersicon esculentum) root cultures of Meloidogyne javanica susceptible and resistant cultivars infected with M. javanica. Uninfected cultivars produced very low amounts of ethylene. Relatively high amounts of ethylene were produced by the infected susceptible cultivars. Peak production of 1.6 n moles * g root(1) * h(1) occurred between 9...
متن کاملEffect of chitosan on root-knot nematode, Meloidogyne javanica
In our study two different chitosan with low and high molecular weight at different dilutions i.e. standard, 1:1, 1:2, 1:3, 1:4, 1:5 and 1:10 were evaluated against root-knot nematode, Meloidogyne javanica in vitro and in vivo under greenhouse conditions. In vitro results revealed that both chitosan with all used concentrations significantly reduced the egg hatching when compared to control. No...
متن کاملEffect of Inhibitors and Stimulators of Ethylene Production on Gall Development in Meloidogyne javanica-Infected Tomato Roots.
Excised tomato roots infected with Meloidogyne javanica produced ethylene at 3-6 times the rate of noninfected roots. This increase in ethylene production started 5 days after inoculation. Gall growth and ethylene production in infected roots were accelerated by 1-aminocyclopropane-1-carboxylic acid (ACC), indole acetic acid (IAA), and ethrel known as ethylene production stimulators. When inhib...

متن کاملInteraction of Root-knot Nematode (meloidogyne Javanica) and Tomato as Affected by Hydrogen Peroxide
The effect of hydrogen peroxide (H2O2) on root-knot nematode (RKN, Meloidogyne javanica) in tomato was investigated. Soil drenching with exogenous H2O2 was done using seven H2O2 concentrations (1, 10, 100, 250, 500, 750 and 1 000 mM) at different application times (24 hours before the time of plant inoculation with the RKN (T1), at the time of inoculation (T2), and 24 hours after the inoculatio...
