Abstract

This experiment carried out in the laboratory of plant tissue culture in the Technical Institute / Musayyib for the period from 1/3/2010 until 1/12/2010 to study the four concentrations of growth regulator 2 . 4 - D is (0 , 1, 2 and 3) ml / liter -1 and licorice extract is ( 0 , 0.25 , 0.50 and 1) ml / liter -1 and the overlap between them in the growth and development of parts of vegetative and Tgazirha to plantlets apricot outside vivo invitro The results showed the following :      The presence of statistically significant differences for all traits when increasing concentrations of growth regulator 2,4-D concentrations and licorice extract , and the overlap between them . The increase was clear to rate traits registered the highest rate at Focus 3 ml / liter -1 for the orderly growth of 2.4 - D has reached 1.62 cm plant height and 136 mg of the weight of soft paper and 8.15 and 2.78 and root lengths of 2.03 cm . While it was noted that the increase in the concentration of licorice extract led to an increase for all traits ( plant height 1.13 cm and 127.5 mg of the weight of the soft and 6.66 paper , 1.37 root lengths 1.33 cm) recorded a combination between the concentrations of 2,4-D and licorice extract (3 ml / liter -1 2,4-D and 1.0 ml / liter -1 higher results and all the qualities and the increase was clear was reached (1.58 cm high plant 0.140 g weight mushy , 9.00 and paper and 4.4 root and the rate of the length of 2.28 cm ) compared to treatment comparison which gave the lowest rate and all the qualities .
