Emasculation is done before the anthers are mature and the stigma has become receptive to minimise accidental self-pollination.
Emasculation is generally done in the evening, between 4 and 6 p.m., one day before the anthers are expected to dehisce or mature and the stigma is likely to become fully receptive.
Immediately after emasculation, the flowers or the inflorescences are enclosed in suitable bags of appropriate size to prevent random cross-pollination.
