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 producedby non radiation and radiation seeds and explants in solid MS mediumwith different concentration of growth regulators ( BA+NAA) . the bestresponse observed in forming callus radiation seeds and explants withsome 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 , andthe high doses of gamma radiation 0.9 K.rad stimulated callusdifferentiation and created also one step regeneration plants , especiallythe hypocotyle callus.
