Pulsed excimer laser radiation influences in vitro culture of Algerian ivy

Use of gamma rays and X rays with in vitro cultures has been used to isolate unique plant types (Chevreau et al., 1989). Exposure of in vitro cultures to gamma and X-ray radiation has resulted in the mutagenesis of grape (Kim et al., 1989) and reduced regeneration of maize lants (Moustafa et al., 1989). Our study was initiated to find an alternative method for the elimination of biological contaminants from in vitro cultures of Algerian ivy (Hedera canariensis L.)
