Abstract
This study investigated the effects of different concentrations of an exogenous plant growth regulator (Stimulate™, a commercial product consisting of a mixture of auxin, gibberellin and cytokinin), on some post harvest quality attributes of 'Albaron' tomato fruits, grown in greenhouses. Foliar applications of Stimulate™ were made every fourteen days. After harvesting, fresh and dry mass, diameter and colour per tomato fruit were assessed. The dry mass were 5.23, 5.68, 5.26 and 5.35 g/100 g fresh mass, the diameters were 6.06, 5.72, 6.35 and 6.24 cm, respectively for control (water) and increasing concentrations: 0.5, 1.0 and 2.0 μg/ml for each GA and IBA, with corresponding 0.9, 1.8 and 3.6 μg/ml of kinetin. No significant differences were observed. The rate of colour change from red orange to red was faster for the treated (7 days) compared to the control (9 days) plants. A positive correlation was observed for diameter and fruit mass. These results suggested that the exogenous application of the plant growth regulator Stimulate™ had no effect on the size of the fruits, but hastened colour changes.
