Abstracts |
Tomato seedlings were inoculated with 125, 250 and 500 chlamydospores of the vesicular arbuscular mycorrhiza (VAM), Glomus sp., in the nursery. Nematode (Meloidogyne incognita) inoculum, i.e. ~350 juveniles per plant, were added to the pots as a 2-cm deep trench around the stem base. P was added as rock phosphate at concentrations of 75 or 100% of the recommended dose (75 kg/ha). VAM root colonization and sporulation increased with increasing VAM inoculum density, but decreased with increasing rate of P either in the presence or absence of nematode infection. VAM sporulation decreased in the presence of nematode infection. Plants grown in soil containing the lower P rate and higher VAM inoculum density showed increased shoot growth either in the presence or absence of M. incognita. On the other hand, root weight increased in the presence of nematode infection regardless of P rate and VAM inoculum density.. |
