Abstract:
The phenological observations in Polyalthia fragrans were made on various phenophases such as leaf flushing, production of young flowers, maturation of flowers, abscission of flowers, production of young fruits, maturation of fruits and ripening of fruits in Pattighat forest range of Western Ghats, situated in Sampaje, Madikeri district of Karnataka during 2013–15. The flushing in Polyalthia fragrans throughout the year confirmed the evergreen character of the species with the flushing peaks during October–December. The floral initiation was during October and continued till December. The fruit maturation was during April to May and the seed dispersal in May to June, during which time the moisture content in the soil was likely to help in good regeneration. The germinated seedlings get established during June to September.
