Abstract: In order to ascertain growth developmental rule of strawberry fruit and dynamic rule of the nutrition ingredient change,the experiment material are Daselect,shimei 4,shimei 5 and shimei 6. It was studied that fruit growth developmental rule and rule of the nutrition ingredient change from flower latter 3 days to fruit mature. The result showed that the fruit length and width continuously is steadily growing during the whole growth developmental process; The fruit weight and the fruit volume of different culvars fast grows after flowers latter 15 days; The sugar content assumes the rising tendency in the overall during the strawberry fruit growth process; The acid content starts to increase from flower latter 3 days,and achieves biggest to half red period,then begin to drop in mature period; vitamins C content continuously increases from the young fruit period to the mature period,but the vitamin C content achieves the maximum value on turing red period,maturing period drops a little.
