FLOWER STRUCTURE AND THE INFLUENCE OF DAYLENGTH ON FLOWER INITITATION OF SERRURIA FLORIDA KNIGHT (PROTEACEAE)

Reproductive development of Serruria florida commences during March with the terminal inflorescence slowly increasing in weight while the apical meristem is producing peduncular bracts (pb). Following pb initiation the growth rate increases, the apical meristem enlarges and produces 30–40 bracts of which 10–15 abort shortly afterward.
Incandescent light applied from 5 March 1988 from 6 pm to 8 am prevented flower formation indicating that the natural short days of winter are required for flowering.
