The effect of mycorrhizal symbiosis in orchids was studied in five Dendrobium hybrids ; D. Pompadour, D. Udom Sri, D. Sonia, D. Ohla and D. Channel. Two fungi species (named A and B) were originally isolated from Dendrodium sp. were inoculated to the root of orchid plantlets. The growth of orchids were monitored at every two-week intervals up to tenth week of fungal inoculation. There were significant diferences in the increase in the plant height, root length, root number, and leaf number when inoculated with both fungi. The growth stimulus occurred very rapidly, and some occurred in the roots which were not seen to contain digested pelotons (coiled intracellular hyphae).
