| A laboratory experiments were carried out in the laboratory of tissue culture, Ministry of Agriculture in Abu Ghraib from June 2012 to December 2013 to study the (effect of four different concentrations of BA and Kinetin on the production of micro potato tubers in vitro of potatoes (Lizita cultivar) four concentrations of BA (0,2,4,6 mg/ L-!) in MS media supplemented with (80g.L-1) were used sucrose. Completely Randomized Design with ten replicates were adapted using L.S.D test level significance .The results Indicated that the treatment (4mg/L-1) was significantly differences from other treatments in (the number of tubers/plants, diameter of tuber, fresh weight, plant yield and dry weight) when it gave (3.2 tuber/ plant, 5.40 g,0.20 g,0.578g and 0.019 g) respectively. Also four different concentrations of Kinetin (0,3,6,9 mg.L-1) in MS media supplemented with (80gm.L-1)were used sucrose, The results indicated that treatment (6mg,L-1) was significantly higher from other treatment in( the number of tubers , dimeter of tuber,tuber fresh weight, plant yield and dry weight) which gave (3.5 tuber/plant, 6.11 mm, 0.33 g,1.155g and 0.022g) respectively . |
