Host suitability of date palm seedlings to Meloidogyne incognita as influenced by stress of plant age
Pakistan Journal of Nematology 33 (2), 191-193
Abstract: The influence of date palm Phoenix dactylifera L., seedling age was determined on nematode reproduction to susceptible date palm cv., Sewi inoculated with root-knot nematode, Meloidogyne incognita. Seedlings of 4, 3 and 2 month old supported more nematode populations than 0 and 1 month old seedlings as indicated by number of galls and egg-masses on roots and juveniles in soil but they were rated as less affected by root-knot nematode depending their plant growth vigor. It is concluded that younger date palm seedlings seem to require root tissue maturation before expressing full resistance against root-knot nematode.
