Growth response of Hevea brasiliensis seedling rootstock to inoculation with vesicular-arbuscular Mycorrhizal fungal species in steam-sterilised soil

The growth response of Hevea brasiliensis PB 5/51 seedling rootstock to inoculation with ten vesicular-arbuscular mycorrhizal (VAM) fungi was assessed in two sandy and phosphorus (P)-deficient sterilised soil in the glasshouse. After twenty-two weeks of growth only two out of ten endophytes (Glomus clarum and an unknown Glomus sp. UGX) increased shoot dry weight significantly over the uninoculated controls but none increased root fresh weight. Stem diameter and height growth from inoculation with all endophytes were also not different from the controls. On the other hand mycorrhizal infection by Acaulospora dilatata Acaulospora spinosa Gigaspora margarita Glomus sp. UGX and E. colombiana caused increased leaf P concentrations. The amount of root infection was not related to improved plant growth. It was concluded that growth and P uptake by H. brasiliensis in sterilised soil were improved in the presence of efficient VAM fungi

Abstract

The growth response of Hevea brasiliensis PB 5/51 seedling rootstock to inoculation with ten vesicular-arbuscular mycorrhizal (VAM) fungi was assessed in two sandy and phosphorus (P)-deficient sterilised soil in the glasshouse. After twenty-two weeks of growth only two out of ten endophytes (Glomus clarum and an unknown Glomus sp. UGX) increased shoot dry weight significantly over the uninoculated controls but none increased root fresh weight. Stem diameter and height growth from inoculation with all endophytes were also not different from the controls. On the other hand mycorrhizal infection by Acaulospora dilatata Acaulospora spinosa Gigaspora margarita Glomus sp. UGX and E. colombiana caused increased leaf P concentrations. The amount of root infection was not related to improved plant growth. It was concluded that growth and P uptake by H. brasiliensis in sterilised soil were improved in the presence of efficient VAM fungi
