Abstract

This study carried out in the laboratory of plant tissue culture of the College of Technology / Musayyib in order to determine the effect of different concentrations of 2,4-Dihydroxyphenoxy acetic acid 2,4-D)) in the production of vegetable oils Linoleic acid and Oleic acid from callus sunflower seeds Helianthus annus L . Sterilized seeds were planted after removing the cover on the central sterile and MS Almjhzb 2,4-D concentrations 2.0,1.5,1.0,0.5,0.2,0.1,0.0 ) mg / L) and took the results after 40 days from sowing . The results showed the superiority concentrations ( 1.5 to 1.0) mg / L 2,4-D morally " in the average weight of the soft callus concentrations as compared to the rest gave ( 20.2 and 20.6 ) g on the relay , while the treatment did not give any response to the control callus formation . It was the Tercizin themselves significant effect in increasing the average dry weight morally " concentrations as compared to the rest gave moderate " amount ( 5.8 and 6.1 ) g on the relay . Aydan and the results showed a higher amount of oil Oleic acid concentration was at 2.0 mg / L 2,4-D , reaching 0.68 mg / g dry weight , which differed significantly " from the rest of concentrations except focus 1.5 mg / L ( 0.60 mg / g dry weight) , while the highest amount of oil Linoleic acid concentration was at 1.0 mg / L 2,4-D , amounting to 0.80 mg / g dry weight , which significantly exceeded " all concentrations , in terms of this amount was significantly decreased in high concentrations of 2,4-D and down " to lower the amount of focus when 2.0 mg / L 2,4-D , which amounted to 0.40 mg / g dry weight . conclude that the amount of vegetable oil to increase in callus increasing the concentration of 2,4-D in the diet compared to the control center .
