Effect of Meloidogyne incognita on Selected Forest Tree Species
Four or five growth stages of 14 forest tree species were tested for susceptibility to Meloidogyne incognita at five inoculum levels. Responses ranged from the highly susceptible 'China fir' to immune 'Taiwania'. Even highly susceptible species became increasingly tolerant at lat...

| Zusammenfassung: | Four or five growth stages of 14 forest tree species were tested for susceptibility to Meloidogyne incognita at five inoculum levels. Responses ranged from the highly susceptible 'China fir' to immune 'Taiwania'. Even highly susceptible species became increasingly tolerant at later growth stages, thus root-knot appears to be a greater problem in nurseries than in established forests. Heavily suberized cells which restricted nematode development was the predominant host response in Norway spruce, and in the jack, scotch, and Virginia pines. Adult females in jack and scotch pine, which elicited a minimum of suberized tissue, were found adjacent to infection sites showing maximum suberization which indicates that resistance can be highly localized and variable within an individual host. A few gravid females, but no giant cells, were observed in these two species |
