Embryogenic callus cultures of ginger were induced from young leaf segments taken from in vitro shoot cultures. Among the four auxins tested in Murashige & Skoog medium, dicamba at 2.7 IxM was most effective in inducing and maintaining embryogenic cultures. Efficient plant regeneration was achieved

β¦ Synopsis
High frequency plant regeneration via somatic embryogenesis has been induced from in vitro shoot-base cultures of seedlings of garden leek (Allium porrum L.). Four main steps are involved in the procedure using BDS medium:
-shoot multiplication with 17.6 mM benzyladenine; -induction of nodular callus from the in vitro shoot base with 9 mM 2,4-dichlorophenoxyacetic acid; -initiation of embryogenic callus from nodular callus with 9 mM 2,4-dichlorophenoxyacetic acid + 7.6 mM abscisic acid; -plant regeneration from embryogenic callus with 9.8 mM N6-(2-isopentenyl)adenine. The presence of 2,4-dichlorophenoxyacetic acid in the medium and light conditions were shown to be essential for nodular callus induction and somatic embryogenesis. Abscisic acid was not a prerequiste for somatic embryogenesis, but it significantly increased the frequency.

Somatic embryos isolated from mature seed-derived cotyledon cultures of cassava (Mannihot esculenta Crantz) underwent direct secondary somatic embryogenesis or plant development under appropriate incubation conditions. Isolated somatic embryos were subjected to a two-stage culture procedure similar
Leaf explants of Nerium oleander L. produced masses of callus when both an auxin and a cytokinin were included in the medium. Leaves cultured on the B5 medium of Gamborg et al. supplemented with 2,4-dichlorophenoxyacetic acid (2,4-9; 9.05 ~tM) plus benzyladenine (BA; 4.4 laM) produced callus and pro
A successful procedure has been designed for the regeneration of plantlets from leaf sections of the self-pollinating species, Medicago suffruticosa. Callus growth was promoted by a 4-week culture period on liquid Kao's medium containing 4.9 #M benzyladenine and 4.5 #M 2,4-dichlorophenoxyacetic acid
Leaf discs from olive (Olea europaea L.) grown in vitro and immature zygotic embryos collected at 50, 75, 90 and 105 days after full bloom were tested for their somatic embryogenic capacity. The embryos were grown in half-strength MS medium and halfstrength OM medium with BAP combinated with either
