چکیده
|
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.
