Abstract
Tomato seedlings were grown in sterile, phosphorus deficient soil and inoculated with four species of vesicular-arbuscular mycorrhizal (VAM) fungi in 15 possible combinations. Mycorrhizal plants exhibited a significantly higher shoot length and biomass, than non-mycorrhizal plants ( P > 0.05). VAM also increased host tissue N and P concentrations. Among the VAM combinations, inocula containing all four endophytes promoted markedly better shoot length and biomass than other combinations, although spore yields were lower in mixed inocula. Mycorrhizal dependency (MD), percentage increase of biomass compared to controls, was also more in quadruple combination than in either triple or double combinations. A negative interaction on plant growth and biomass was observed between Glomus aggregatum and G. fasciculatum. This effect was nullified when more species were added to this combination.
