[Show abstract][Hide abstract] ABSTRACT: Nolina recurvata Hemsl. is a very decorative indoor plant but difficult to micropropagate vegetatively. In vitro cuttings failed to induce adventitious rooting. Investigations for a rapid micropropagation using β-cyclodextrin added to the rooting medium has solved the problem. Rooted N. recurvata plantlets were obtained after successive stages of various culture media.Initiation and in vitro multiplication of this plant was possible with lateral buds cultured in Murashige and Skoog medium supplemented with 4.45 μmol of BA and 0.5 μmol of IBA. The number of axillary shoots by explant obtained was 6.In vitro rooting was obtained in MS medium (1/2 strength of minerals salts) supplemented with β-cyclodextrin. This substance, at 1.76 mmol associated with 5 μmol of IBA, improved quality and the rooting rate by 100%.

[Show abstract][Hide abstract] ABSTRACT: In vitro Multiplication and Bulb Formation of (Gladiolus grandiflorus Hort.). In order to set up a new bulb formation and micropropagation of gladiolus in vitro, trials were undertaken using two ornemental gladiolus cultivars 'Peter pears' and 'White friend ship'. The explants used are apical buds with 2 to 3 mm length taken from the cormes. In vitro initiation and multiplication were done for the two cultivars on Murashige and Skoog medium to which 2 mg. l-1 of BA and 0.5 mgl-1 of AIB were added. In vitro root development and bulb formation have been occurred in MS Agar Agar medium with 0.5 mg.l-1 of AIB 30 days later than the same MS medium containing 6% of saccharose and without Agar.
