Abstract：Using flowering Chinese cabbage（Brassica parachinensis Bailey）‘Youqing 60 tian’
as material，the experiment was conducted to investigate the effects of foliar application of different
concentrations of sucrose on soluble sugar content and yield of flowering Chinese cabbage．The results
showed that the contents of total soluble sugar，reducing sugar，fructose，glucose in the stems were
all higher than in the blades，while the sucrose in the stems were lower than in the blades．Treatment
of appropriate concentrations of sucrose could significantly increase the contents of soluble sugar in
flowering Chinese cabbage，but high concentration treatment would inhibit the accumulation of soluble
sugar．Foliar application of 50 mg·L-1 sucrose could remarkably increase the contents of total soluble
sugar，reducing sugar，sucrose，fructose and glucose．Different concentration of sucrose treatment
had little influence on the single plant yield.
