Changes in the reducing and non-reducing sugars during fruit bud differentiation in mango hybrids

Abstract

The forms of sugar and the ratio of reducing to non-reducing sugar and the total sugars have considerable impact on fruit bud differentiation among the other biochemical factors. Sampling in three mango hybrids, Mallika, Amrapali and Pusa Arunima was done end of August to the end of December. The level of reducing sugars ranged from 3.70 to 6.95 mg/g FW and non-reducing sugars 0.75 to 2.45 mg/g FW during the study period in Amrapali, indicating their increase during FBD for the next year flowering. The trend was similar in the three genotypes being regular bearer.
