Effect of IBA and NAA on rooting and axillary shoot outgrowth of 'Himalayan' mulberry stem cutting

Abstract

The effect of 4 different concentrations (500, 1000, 2000 and 3000 ppm) of Indole-3-Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) to root and shoot of 'Himalayan' mulberry stem cutting were studied. The result showed that after 40 days of cuttings, 3000 ppm of IBA was the best result of concentration showing 3000 ppm of IBA was 93.33 percent survival rate, 86.67 percent of rooting, 18.8 roots, 10.82 centimeters of root length, 93.33 percent of axillary shoot outgrowth, and 13.11 centimeters of axillary shoot length, 5.79 leaves, 5.1 centimeters of leaf width, and 6.84 centimeters of leaf length. Therefore, IBA 3000 ppm is suitable to use in “Himalayan” mulberry propagation by stem cutting.
