Field experiments were established during the 1988 and 1989 growing seasons, to determine the effect of mini-tunnel management systems on floral development and fruit set of tomato (Lycopersicon esculentum Mill.). Two types of floral abnormalities reported to be caused by temperatures above 30$ sp circ$C were observed, namely: style exsertion and splitting of the antheridial cone. Clear vented and white non-vented mini-tunnels reduced the incidence of both these abnormalities compared to the controls in 1988. As a consequence these two types of mini-tunnels also had the greatest percentage fruit set and total marketable yield of the first three clusters. In 1989, none of the mini-tunnels tested significantly increased percentage fruit set or marketable yield. The cultivar Springset produced ripe fruits an average of 4 days before Hope#1 and 7 days before Celebrity in both 1988 and 1989.
