Self-pollination in the genus Erica

, 2009
The ability of flowers to self-pollinate was investigated in eight species of the diverse Erica genus. Self-pollination was found to occur in five out of the eight species, with mainly bird pollinated species having a high degree of selfing. The use of a broken anther ring as an indication of visitation and pollination of the flowers was also ...
