Research outcome for enhancement production of pummelo Hom Hat Yai

Abstract

Klong Utapao basin of Songkhla province. It has been grown for commercial purposes recently. This pummelo has prominent characteristics of vigorous tree, large fruit, thick rind, purple to red flesh and acidsweet taste, and is seedless. Because it is a new crop with small scale planting, there is limited plant basis information and few research reports compared to other main economical crops. Since the year 1994 there are 3 thesis research titles focusing on flowering and fruiting of this crop. They are 1) Floral biology and pollination of pummelo cv. Hom Hat Yai by Kaewtubtim (1994), 2) Effect of pollination on fruit setting, seediness and fruit qualities of pummelo cv. Hom Hat Yai by Karnjanapakorn (2000), 3) The influence of gibberellic acid (GA3) on fruit set and premature fruit development of pummelo cv. Hom Hat Yai by Dumnoi (2001). This paper reports and discusses those research outcomes for enhancement of production of pummelo cv. Hom Hat Yai in 3 aspects. 1) This pummelo sets fruit parthenocarpically. 2) This seedless pummelo sets seeds with cross pollination. 3) This pummelo sets more seedless fruits by GA3 application
