In sweet orange flowering takes place from Jan to Feb in Raipur. It varies from region to region.
Two types of inflorescences were observed i.e. leafy and leafless. The flowers are borne on current season’s growth in the axils of leaves either solitary or in cymes with five sepals, five petals and twenty stamens with superior ovary.
The maximum opening of flowers and dehiscence of anthers take place in morning hours (10.00 A.M. to 12.00 noon). Stigma became receptive just after anthesis and remained receptive till 72 hours for pollination. The maximum receptivity was recorded on the day of anthesis.
