Important Role of Mycorrhiza for Seed Germination and Growth of <i>Dendrobium</i> Orchids

Indonesia is a tropical country that has natural forests and suitable for orchid species habitat, leading to more than 5,000 of orchids grow. The area the main distribution centre epiphytic orchids, one which Dendrobium, grows 1,000 throughout world. Orchid seeds are very small do not have an endosperm, making germination difficult in their habitat. Mycorrhizal association with plays role survival nature through seed growth. This study aims provide deeper understanding about important mycorrhiza growth Dendrobium. mechanism mycorrhizal begins initial contact fungus orchid, hyphae enter cortex cells form peloton, peloton lysis, exchange nutrients occurs. mostly found groups Dendrobium Rhizoctonia (Epulorhiza, Tulasnella, Rhizoctonia).
