movement of labeled amino acids from leaf blades to sheaths was followed after supplying ( 13 ) nh ( 3 ) gas , ( 14 ) co ( 2 ) , or ( 14 ) c-amino-acids to attached blades of barley plants.blades of turgid and wilted plants fed ( 13 ) nh ( 3 ) ( at about 120 to 700 microliters per liter ) had incorporated ( 13 ) n mainly into free glutamine and glutamate after 30 minutes , and turgid blades had exported 1 to 3 % of the assimilated ( 13 ) n to the sheaths , mostly as glutamine and glutamate .
