FIGURE 1.

Transpiration rate in intact plants during light (A) and dark (B) period in pot rose cv. ‘Toril’ grown at moderate (61%) or high (92%) RH, without (open columns) and with (solid columns) additional MOV. Measurements were conducted throughout three consecutive days in fully grown plants, starting when the flower bud had cylindrical shape and pointed tip. Values are the mean of 14 intact plants and bars represent the SEM. Different letters indicate significant differences according to Fisher’s LSD test (P = 0.05).
