Ison, R. L. and Humphreys, L. R. (1984). Day and night temperature control of floral induction in Stylosanthes guianensis var. guianensis cv. Schofield. Annals of Botany, 53(2) pp. 207–212.

Abstract

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).
