Abstract

Three species of Medinilla were monitored from April-October 2002. The inflorescences of M. magnifica Lindl., M. minutia Merr. and Medindla sp. were observed from the appearance of inflorescence to bud formation, flower to fruit formation and fruit formation to maturity. New inflorescences of M. magnifica and Medinilla sp. were observed during the study period. Medinilla magnifica inflorescences started to emerge on the months of February to August while inflorescences of M. miniata appeared only in the months of February to April. The length of time required for the inflorescences of each species to yield mature fruits was approximately 4-5 months for M. magnifica and ,Medinilla sp. and 3 months for M. minima. Flowers of all species observed remain open for 1-2 days. Medinilla sp. had the lowest flower set percentage (76%). Both M. magnifica and M. miniata had 100% flower set. Consequently, Medinilla sp. had the lowest fniit set percentage (7.9%) followed by M. magnifica (52%) and M. minata (53.6%). Strong winds and heavy rains damaged the upright inflorescences of Medinilla sp. and resulted in relatively low flower and fruit set percentage.
