Abstract
The effect of daylength upon floral initiation, flower position, and associated features was measured in six white clover (Trifolium repens) varieties Most plants initiated flowers in the longest days (16 h). The varieties of more southerly origin and with large leaves had a greater spread of response to daylength. Increasing daylength increased the number of buds becoming inflorescences in all varieties except Milkanova in which the reverse was true. Peduncle length and nectar production were both greatest in the longest days.Keywords
