1. a production has the method for plant of deposition fabric that corresponding deposition fabric with control plant is compared the endogenous carbohydrate content of total carbohydrates that raising is arranged or soluble-carbohydrate content or sugariness or raising, it is characterized in that, but described method comprises from multiple comprising its nucleome and linking to each other with operating method with transcriptional control element and a kind of endogenous sugar of this plant of a kind of catalysis of encoding changes in the transgenic plant of polynucleotide of carbohydrate metabolism enzyme of allos sugar and selects the transgenic plant that produce described carbohydrate metabolism enzyme with certain level or functionally active, thereby compare with the corresponding deposition fabric of control plant, the total carbohydrates of this transgenic plant deposition fabric or soluble-carbohydrate content or sugariness or described endogenous carbohydrate content are improved.
