Foragers include honeybees, butterflies, wasps, flies and ants. The flowers are self-compatible, pollinate both by self and cross pollination. In Allogamy (Hand cross pollination), highest mean percentage of fruit set was observed as 71 and 75% respectively for the period 2012-13 and 2013-14.

Keywords Cinnamomum sulphuratum;phenology;pollination;breeding system.
