Effect of Growth Regulators and Mist on Rooting in Stem Cuttings of Plum (Prunus Domestica L.)

The studies were conducted on the effect of some growth regulators and mist on rooting in stem cuttings of ‘Santa Rosa’ plum. IBA and NAA were applied singly and in equal combinations at the concentrations of 1,000 2,500, 5,000 and 7,500 ppm. Two seasons of planting and mist versus without mist were also compared. IBA at 1,000 ppm proved to be the best treatment with respect to rooting (25.77 per cent against 0 in control), number of primary roots and length and diameter of the longest root. IBA also proved superior over NAA or IBA + NAA. The beneficial effect of growth regulators decreased with their increasing concentrations. Mist proved superior over without mist while December planting proved superior over November planting.
