Studies were conducted with Tochiotome strawberry cultivar (Fragaria×ananassa cv. Tohiotome) grown in a plastic greenhouse for studying the roles of sucrose and hexose metabolizing enzymes in sugar accumulation in fruit. The strawberry fruit were sampled from 1 to 8 weeks after full blossom (WAFB). The contents of sucrose, glucose and fructose and the activities of sucrose phosphate synthase (SPS), sucrose synthase (SS), acid invertase (AI), neutral invertase (NI), hexokinase (HXK) and fructokinase (FRK) we...

Sugar concentration is a primary determinant offruit quality in strawberry. Sugars are in the forms ofglucose, fructose and sucrose in strawberry fruit[1]. Usu-ally, glucose concentration is almost equal to that offructose, and hexose content (sum of gluc
