Abstract
Studies on the seed production, modes of dispersal and regeneration patterns of threatened tree species are crucial for the management of their genetic diversity. The seed bank estimation of Calophyllum apetalum was assessed from three different locations of Western Ghats of Karnataka, using two factorial completely randomized design. The results revealed the seeds are dispersed by hydrochory and mammalochory. The post seed dispersal, seed bank estimation studies yielded a high seed density near the base of tree trunks, but it was varied between the distances and locations. The results revealed seed densities are insignificant among the forest ranges and significant with the distances. The in-situ regeneration studies revealed an insignificant relationship between the mean regeneration among the forest ranges and the distances. Also, the ex-situ regeneration studies resulted an insignificant relationship among forest ranges and the distances from which the seeds were collected. The highest seed germination through ex-situ regeneration suggested it, as a best suitable method of conservation of this species.
