A COMPARATIVE-STUDY OF THE EFFECTS OF USING THE HONEYBEE AS A POLLINATING AGENT OF GLASSHOUSE TOMATO

Four methods of pollination (natural, honeybees, vibrating wand and honeybees plus vibrating wand) were compared factorially in an experiment with two, late-season cultivars (Criterium and Gold Star) of glasshouse tomatoes. Yield and quality of harvestable fruit was considerably improved by using honeybees and/or an electric vibrating wand to aid the pollination of flowers. Increases in yield due to the pollination treatments were greatest during the first half of a period of cropping from late May until early October. The highest fruit-sets and yields of 'Criterium' and 'Gold Star' were obtained with honeybees. Consideration is given to the choice of pollinating agent and the commercial opportunities for growers.
