And the leaf transportation percentage of 14C photoassimilates was 14.6% increased.The 14C-soluble sugar distribution percentage of CCC treatment in leaf and stem were less than those of the control,respectively,but the 14C-soluble sugar distribution percentage of CCC treatment in tuber and root were more than those of the control,respectively.The 14C-starch distribution percentage of CCC treatment in leaf,stem and root were less than those of the control,respectively.but the 14C-starch distribution percentage of CCC treatment in tuber was more than that of the control.The radioautography also indicated that photosynthate transport from top tissues to tubers was faster in CCC treatment than that in control.These results showed that appropriate concentrations at 1.5 g L-1 of CCC significantly improved the photosynthetic characteristics,transport and distribution capability of photoassimilates in potato,and as a result tuber yield would be increased.The pattern of translocation shown is held to reflect the activities of the various metabolic sources and sinks,the activities of these sources and sinks being hormonally controlled.
