Abstract:
Sweet cherry rootstock ‘Gisela’ cutting seedling was used as material,the effects of fulvic acid (metabolic antitranspirant) on photosynthetic rate,transpiration rate,stomatal conductance and water use efficiency were analyzed in order to study the transplanting survival rate of ‘Gisela’ cutting seedling.The results showed that the transpiration rate,stomatal conductance were evidently reduced by foliar spraying fulvic acid,while water use efficiency was improved,the effects of fulvic acid were more remarkable along with the spraying concentration increased.The depressing in photosynthesis was mainly caused by stomatal factors.Compared with clean water control,fulvic acid solutions of 0.08 g?L-1,0.16 g?L-1,0.32 g?L-1 increased the transplanting survival rates by 4.0,8.3 and 6.7 percentage point，respectively.In conclusion,spraying fulvic acid just after transplantation could reduce the water loss through adjusting stomatal opening,the effect fulvic acid solution of 0.16 g?L-1 was the best,and then the survival rate of transplantation was increased.
