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.

和叶运输的百分比为14 C photoassimilates为14.6 ％升高为14 C -可溶性糖分配的百分比CCC认证，在治疗叶和茎均小于那些控制，分别为，但14碳-可溶性糖分配的百分比中华基督教会在治疗块茎和根多于那些控制，分别为14 C -淀粉分配的百分比CCC认证治疗叶，茎，根均小于那些控制， respectively.but了14 C的淀粉分布的百分比CCC认证的待遇是块茎以上的对照radioautography还表示，光合产物的运输，从顶端组织，以块茎快，在CCC认证的待遇比在control.these结果表明，适当浓度一点五克L - 1的CCC产品大大提高了光合特性，运输和分配的能力， photoassimilates在马铃薯，结果块茎产量将增加，模式易位显示举行，以反映活动的各种代谢源和汇，这些活动的源和汇正激素的控制。
