Abstract

【Objective】The study was done in order to establish a method for convenient,economical and mass reproduction of root-knot nematodes Meloidogyne spp..【Method】Assays were designed and carried out to evaluate root growth indices of Ipomoea aquatica,Solanum tuberosum and Lycopersicon esculentum inoculated with or without root-knot nematodes in sand planting.【Result】The results showed that after planting the three plants in sand for 30 days,root system of S.tuberosum was the strongest,followed by the I.aquatica and that of L.esculentum was the weakest.The root system of I.aquatica had the longest period,10 months.Inoculating 1 000 juveniles of Meloidogyne incognita each plant and letting the plants grow for another 50 days,the number of the root knobs,egg masses and total nematodes in root system of I.aquatica was 866.8,864.4 and 1 592.2 respectively,much higher than those from S.tuberosum(651.6,643.4 and 1 106.0) and L.esculentum(222.6,234.0 and 373.8).In addition,M.javanica and M.arenaria were also inoculated to I.aquatica roots,and the results were similar with M.incognita.【Conclusion】I.aquatica was very adapted to sand watering with nutrient fluid,and had a longer growth cycle and was easy to be controlled,so I.aquatica was a good choice to reproduce in quantity and could preserve root-knot nematodes for longer time.
