Abstrakt: The experiment was conducted in Fadak Company in tissue culture labs, Basrah, Iraq, to study the effect different concentrations of benzyl adenine and naphthalene acetic acid, in vitro (papaya hybrid). The treatment combination of MS medium + 1.0 mg L-1 BA and 0.5 mg L-1 NAA has been recorded the highest number of shoots, reached to 4.7 shoot explant- 1. The treatment combination of MS + 0.5 mg L-1 BA + 0.5 mg L-1 NAA gave the lowest mean number of shoots with 1.6 shoot explant-1. The treatment combination of MS + 0.5 mg L-1 BA + 0.5 mg L-1 NAA has achieved the best number of leaves per shoot, reached to 3.9 leaves shoot-1. The treatment combination of MS + 1.0 mg L-1 BA + 0.5 mg L-1 NAA has been recorded a high length of shoot, reached to 1.06 cm. The highest fresh weight of the shoots was 0.172 g recorded by the treatment combination of MS + 1.5 mg L-1 BA + 0.5 mg L-1 NAA. While, the treatment combination of MS + 1.5 mg L-1 BA + 1.0 mg L-1 NAA achieved the highest dry weight mean of shoot reaching to 0.052 g. [ABSTRACT FROM AUTHOR]
