Abstract (EN):
Friable calli and cell suspension cultures were obtained from leaf segments of Euphorbia characias L. subsp. characias, in Murashige and Skoog (MS) basal medium supplemented with 1g.l-1 casein hydrolyzate (CH), 5mg.l-1 ascorbic acid, 1.0mg.l-1 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.75mg.l-1 benzyl adenine (BA). The highest callus specific growth rate (¿=0.085.day-1), calculated for 1 year old calli cultures, was obtained with 0.25 mg.l-1 2,4-D and 0.50mg.l-1 BA. Suspension cultures started with an inoculum of 8.0×104 cells.ml-1 in supplemented liquid MS medium, gave a specific growth rate ¿=0.256.day-1. © 1989 Kluwer Academic Publishers.
