Abstract

External morphology of fruits and seeds, seed germination and seedling growth performances of rain tree (Albizia saman (Jacq.) Merr, ipil ipil (Leucaena leucocephala (Lam.) deWit.) and mandar (Erythrina indica Linn.), were studied in a nursery. The length, breath and number of seed per fruit were found the highest in ipil ipil and the lowest in mandar. The length, breath, thickness and dry weight per seed were the highest in rain tree. Germination percentage was found the highest both rain tree and mandar in polybags and for ipil ipil in seed tray condi tion. Seedling growth performances showed good relation with seasonal variations. Height and diameter growth showed sharp rise during wet season and continue to rise up to semi -dry period. During dry period, there was very less growth in height and diamete r. Leaf production also showed the same trend with seasonal variations.
