Biomass Partitioning in Tomato Plants Infected with Meloidogyne incognita.
Tomato plants were inoculated with Meloidogyne incognita at initial populations (Pi) of 0, 1, 10, 50, 100, and 200 (x 1,000) eggs per plant and maintained in a growth chamber for 40 days. Total fresh biomass (roots + shoots) at harvest was unchanged by nematode inoculation with Pi of 1 x 10 eggs or less. Reductions in fresh shoot weight with increasing Pi coincided with increases in root weight...
متن کاملInduced Resistance to Meloidogyne hapla by other Meloidogyne species on Tomato and Pyrethrum Plants.
Advance inoculation of the tomato cv. Celebrity or the pyrethrum clone 223 with host-incompatible Meloidogyne incognita or M. javanica elicited induced resistance to host-compatible M. hapla in pot and field experiments. Induced resistance increased with the length of the time between inoculations and with the population density of the induction inoculum. Optimum interval before challenge inocu...
متن کاملAn In Vitro Test for Temperature Sensitivity and Resistance to Meloidogyne incognita in Tomato.
An in vitro root explant tissue culture technique is described for determining susceptibility of tomato (Lycopersicon esculentum Mill.) breeding lines and cultivars to the root-knot nematode Meloidogyne incognita. Root explants were taken from 2-day-old seedlings cultured for 30 days at 28 C on Gamborg's B-5 medium with or without nematode inoculum. The remaining portion of the root and stem fr...
متن کاملBiochemical Changes in Root Exudate and Xylem Sap of Tomato Plants Infected with Meloidogyne incognita.
Under two monoxenic culture techniques of growing plants (filter paper and silica sand cultures), sugar in root exudate from Meloidogyne incognita-infected tomato increased 133 to 836% over controls. In contrast, amino acids were moderately reduced 52 to 56%. Chromatographic analysis showed that galled root exudate contained three sugars, twelve amino acids, and three organic acids, whereas hea...
متن کاملResponse of Tomato Cultigens to Meloidogyne javanica and Races of Meloidogyne incognita.
Thirty-six cultigens of tomato were evaluated for resistance against Meloidogyne javanica and four races of M. incognita with standards and parameters adopted by the International Meloidogyne Project. Most cultigens were susceptible to the nematodes, including some that were previously reported to be resistant to these nematodes. Ten accessions, namely Pusa-120, Calmart VFN, Panjab 6.NR-7, EC17...
