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.
