This study is concerned with examining the effect of four concentration of corn maize extract (0, 2, 4, 6) ml.L-1 and two concentration of NAA (0, 0.1) mg.L-1.

The results showed the following : The concentration 6 ml.L-1 corn maize extract has given the best growth of fresh weight and highest number of somatic embryos, whereas the concentration 2 ml.L-1 has shown the best embryo growth and resulted in lowering the average of abnormal somatic embryos to 35 % as well as gave the highest average in germination of natural and somatic embryos which was 50 %.

As far as the effect of NAA is concerned, the concentration 0.1mg.L-1 has increased more than the concentration zero in the number of the somatic embryos, it led to lower the average of abnormal embryos to 33.75 % and increasing the germination of the normal somatic embryos to 45 %.

The results showed a significant increase in the interaction between the treatment (2 ml.L-1 of corn maize extract and 0.1 mg.L-1NAA) which lowered the average of abnormal somatic embryos to 20 % and increased the germination of natural somatic embryos to 70 %.

The control interaction showed the less results.
