Abstract
A study was conducted at the tissue culture lab. College of Agriculture/ University of Baghdad and Drug Research Center/ Health Minstry during 2006 - 2007. Results indicated that MS medium supplemented with 30 g/l of sucrose gave the highest values (630.3, 61.6) mg of both fresh and dry weight of callus respectively. However, values of both parameters were reduced with increasing sucrose concentrations up to 60, 90, 120 g/l (478.2, 346.5, 217.6) mg respectively. MS medium supplemented with 30 mg/l of tyrosine gave the highest values of callus fresh and dry weight (429.7, 42.6) mg respectively. MS medium supplemented with 30 g/l of sucrose and 30 mg/L tyrosine gave the highest values (688.0, 67.5) mg of both fresh and dry weight callus. MS medium supplemented with 30 mg/l of tyrosine and 90 g/l of sucrose gave the highest values (2.9, 2.8) mg/g of morphine and codeine from fresh callus weight respectively while the lowest values of morphine and codeine (0.5K 0.2) mg/g from fresh callus weight respectively of control treatment .
