Temperature and photoperiod effects on flowering of six accessions of Kenya clover (Trifolium semipilosum) and the white clover (T. repens) cultivar Haifa were investigated. Temperature had the greater control over flowering in T. semipilosum accessions; day/night temperatures greater than 24/19 (Experiment 1) or 27/22°C (Experiment 2) were inimical to flowering. The results do however support a weak quantitative long-day response for T. semipilosum cv. Safari.
