Effect of Basal Medium, Explants Size and Density on the In Vitro Proliferation and Growth of Date Palm (Phoenix dactylifera L.) Cultivar ‘16-bis’

Abstract

The effect of basal medium, explant size and density on shoot multiplication, growth, rooting and acclimatization of date palm cv. ‘16-bis’ was evaluated. Bud clusters of different sizes (2, 3, 4 and 5 buds per cluster) were cultured at density of 1, 2, 3 and 4 clusters on Murashige and Skoog medium (MS), woody plant medium (WPM) and Nitsch medium (NM) supplemented with 0.5 mg/L 2-naphthoxyacetic acid and 0.5 mg/L kinetin for three months (multiplication phase). Separated shoots of different sizes (
