title: In vitro propagation of two Iranian commercial pomegranates (Punica granatum L.) cvs. 'Malas Saveh' and 'Yusef Khani'.
abstract: An efficient in vitro propagation is described for Punica granatum L. using shoot tip and nodal explants. The influence of two basal medium, WPM and MS, and different plant growth regulators was investigated on micropropagation of the Iranian pomegranate cultivars, 'Malas Saveh' and 'Yousef Khani'. For proliferation stage, media supplemented with different concentrations (2.3, 4.7, 9.2 and 18.4 μM) of kinetin along with 0.54 μM NAA was used. WPM proved to be more efficient medium compared to MS. The best concentrations of kinetin were 4.7 μM for 'Malas Saveh' and 9.2 μM for 'Yousef Khani', resulting in the highest number of shoots per explants, shoot length and leaf number. For both cultivars, half-strength WPM medium supplemented with 5.4 μM NAA was most effective for rooting of shoots. Rooted plantlets were successfully acclimatized and transferred into soil. The micropropagated plants were morphologically uniform and exhibited similar growth characteristics and vegetative morphology to the mother plants.
