Effect of Gamma rays on the textile plantations of parsley plants Petroselinum crispum

This study attained to callus induction from(shoot tips, leaves, hypocotyle and roots) of petroselinum crispum L . plants which produced by non radiation and radiation seeds and explants in solid MS medium with different concentration of growth regulators ( BA+NAA) . the best response observed in forming callus radiation seeds and explants with some doses 'of gamma rays , especially the hypocotyle (0.15and 0.7) K.rad . the best doses of callus growth and durability was 0.3 K.rad , and the high doses of gamma radiation 0.9 K.rad stimulated callus<br />differentiation and created also one step regeneration plants , especially the hypocotyle callus.
