Effect of mixture of charcoal with pyroligneous acid on sucrose content in netted melon (Cucumis melo L. var. reticulatus Naud.) Fruit

Abstract

To determine the effects of mixing charcoal with pyroligneous acid (pyroligneous acid 1: charcoal 4; Sannekka E) on sucrose synthesis in netted melon fruit, five experiments were carried out at 3 locations from 1990 to 1995. All the experiments indicated higher sucrose content in the fruit supplemented with Sannekka E than without Sannekka E. The activity of sucrose phosphate synthase (SPS) increased as the fruit matured, irrespective of Sannekka E application, but the increase was higher in the case of Sannekka E. From the result, it is suggested that the application of Sannekka E increases SPS activity, which promotes the synthesis of sucrose from glucose and fructose in melon fruits.
