Field performance of eucalyptus urophylla inoculated with introduced and indigenous strains of ectomycorrhizal fungus Pisolithus

Abstract

The effectiveness of an isolate of Pisolithus from Australia was compared with a Philippine Pisolithus isolate in promoting the growth of Eucalyptus urophylla on three acid (pH ranged from 4.1 to 5.9, 0005 M CaCI2) sites in the Philippines (Pangasinan, Bukidnon and Surigao). Isolates of Pisolithus were taken from basidiocarps collected under eucalyptus growing in Western Australia and from the Philippines. Generally, the introduced Pisolithus promoted greater wood volume of E. urophylla planted in dry marginal land (Pangasinan) and in logged-over area (Surigao) in the Philippine Pisolithus isolate. Root colonization by the two fungi did not vary but there was a difference in the root colonization levels between sites implying that the prevailing microclimatic conditions on each site had affected the performance of the ECM inoculants. In this study, the number of isolates tested was limited, thus, future field trials should include a wider range of ectomycorrhizal fungi. Further work is required to determine whether the growth responses measured in the two sites (Pangasinan and Surigao) is maintained until the trees are harvested and to monitor the persistence of the introduced mycorrhizal fungi in the field.
