The rarity of Atuna indica, an endemic and endangered tropical tree species of the Western Ghats, India has been analysed in this study. The phenology, floral biology, including pollen–ovule ratio, pollinators, fruit development and biotic interactions in natural dynamics were studied. Extreme reduction in the number of flowering individuals, microhabitat conditions, low fruit set, seed infestation and fruit predation were identified as the factors leading to rarity of the species in situ.Keywords

Inadequate know-how on seed and nursery technology of wild edible fruits is a bottleneck for their commercialization. The seeds of Baccaurea courtallensis lose their viability within six days under ambient conditions and are found to be sensitive to desiccation and low-temperature conditions revealing their recalcitrant nature. The longevity of the seeds could extend up to six months during storage in polycarbonate bottles maintained at 20°C and 40% relative humidity. Coarse river sand was optimized as the ideal sowing medium for seed germination. The application of 3000 ppm naphthalene acetic acid was standardized for clonal propagation for selective breeding of female genetic stock.Keywords
