title: Micropropagation of Capparis decidua (Forsk.) Edgew. - a tree of arid horticulture.
abstract: A method for micropropagation of mature trees of Capparis decidua was developed. Multiple shoots were obtained from nodal explants on Murashige and Skoog's (1962) medium+0.1mgl(-1) NAA+5.0mgl(-1)BAP+additives (50mgl(-1) ascorbic acid and25 mgl(-1) each of adenine sulphate, L-arginine and citric acid) at 28 ± 2°C, 12 h/dphotoperiod and 35-40 μmol m(-2)s(-1) photon flux density. The shoots were multiplied by (i) subculture of nodal shoot segments onto MS +0.1 mgl(--1) IAA+1.0mgl(-1) BAPH+additives, and (ii) repeated transfer of original explant onto MS+ 0.1mgl(-1) IAA+mg l(-1) BAP+additives, at intervals of 3 weeks. Sixty to 70% of the shoots rooted when pulse treated with 100 mg l(-1) IBA in half strength MS liquid medium for 4h, and then transferred onto hormone-free half-strength agar-gelled MS basal saltmedium. Incubation in dark at 33 ± 2°C for 6d favoured root induction. In vitro hardened plants were transferred to pots.
