Floral initiation in seedlings of Stylosanthes guianensis var. guianensis cv. Schofield grown at a photoperiod marginal for flowering (12—11·75 h) was promoted by a combination of low day (25 °C) and low night (16 or 21 °C) temperatures, and completely inhibited by a 35 °C day temperature. Additionally, earliness of floral initiation under naturally decreasing daylength was negatively related to temperature regime over the range 35/30 to 20/15 °C (day/night).
