1. 4 14CO2-feeding to leaf and fruit of satsuma mandarin
14 CO2-feeding experiments were conducted as described by CHEN et al [6 ] . At each of the four developmental stages (27 July , 18 September , 11 October , and2 November) , a fruit , or a leaf closest to an attached fruit , was selected and enclosed in polythene bags in which 1. 85 ×105 Bq of 14CO2 were released at 10 :00 -12 :00 in a sunshine day. The stem was ringed below the fed leaves or fruits to prevent basipetal transport before feeding. Fruits were harvested at 6 , 23 and 47h after feeding 14CO2 for 1h , then separated into peel , vascular bundle , segment epidermis and juice sacs. These components were frozen in liquid nitrogen and then boiled in 80 % ethanol . Sample radioactivity was determined by Wallac 1410 liquid scintillation counter (Pharmacia Company , USA) .
