Studies on the breeding system of Mimusops elengi are still limited in Malaysia.<br />

A study was conducted in Universiti Malaysia Terengganu (UMT) on this species<br />

by observing the flower development and by conducting pollinator exclusion<br />

experiments (open pollination, closed pollination, hand-cross pollination, openemasculated<br />

pollination, close-emasculated pollination) to determine the<br />

breeding system. Identification of potential pollinator was conducted by<br />

capturing the insects visiting the flowers. The development flower to mature<br />

fruit took approximately 4 weeks. During the pollination exclusion experiments,<br />

the flowers were left (open pollination and open emasculated) and bagged<br />

(closed pollination, hand-cross pollination and close-emasculated pollination) to<br />

exclude pollinating agents, and the total number of fruits produced were<br />

calculated, cross pollination treatment shows high pollination success. In this<br />

study, M. elengi is self-incompatibility breeding system. Xylocopa sp. and<br />

Heterotrigona itama were identified as potential pollinator.<br />
