The present work was aimed at proving the hypothesis that, a Ceratobasidiaceae clone of symbiotic fungus from Vanda thwaitesii Hook. f. supports in vitro symbiotic seed germination in other closely related species, V. spathulata (L.) Spreng, a vulnerable orchid species endemic to Peninsular India and Sri Lanka. An attempt was made to co-cultivate V. spathulata seeds on Oat Meal Agar medium with the mycorrhizal fungus to obtain symbiotic germination. Transformation of seeds into different stages assessed at 15 days intervals revealed fast seedling development. Seeds showed germination with the enlargement of embryos and breaking of seed coat, denoted as stage ‘1’ in 7 days. The germinated seeds subsequently developed into enlarged yellowish protocorms (Stage 2) often with absorbing hair from their base (Stage 3) in 30 days. Out of the total germinated seeds, 22.5% were at stage 1; 29.2% at stage 2, and 26.9% at stage 3. Protocorms that reached stage 2 were almost completely developed into stage 3 with absorbing hair and leaf primordia; these were with two expanded leaves and root initials, when observed after 60 days. Fifteen per cent of the embryos reached stage 5 and beyond with 2 fully expanded leaves and 1-2 roots in 90 days. Control seeds without having mycorrhiza swelled and showed 38% germination but did not progressed beyond stage ‘2’, even after 60 days. The symbiotic seedlings having 3-4 leaves and 2-3 roots obtained after 180 days showed 90% establishment after 3-18 months of transfer to the nursery. The results obtained in this study enabled to prove the hypothesis that the Ceratobasidiaceae clone of endophytic fungus known to support symbiotic seed germination in V. thwaitesii is equally effective in V. spathulata, indicating thereby that the strain is not species specific in this case and supports symbiotic germination in other species of Vanda as well. The symbiotic seed germination obtained is highly valuable for restoration/conservation translocation of V. spathulata
