Study on rooting of stem cutting in Barbados cherry (Malpighia glabra L.) under hill zone of Karnataka

Abstract

An investigation was to assess the influence of growth regulators IBA, NAA and their combination on rooting of stem cuttings in Barbados cherry (Malpighia glabra L.) under hill zone of Karnataka. It was observed that, the least number of days (21.33) taken for root initiation, maximum percentage of rooting (80.00), number of root (26.67), average length of root (17.85 cm), length of longest root (23.00 cm), maximum number of primary (8.83) and secondary root (20.83), maximum fresh (2.91g) and dry weight of root (1.15 g) and root volume (4.5 cc) was recorded in cutting treated with IBA 5000 ppm. The less number of days taken for first sprouting (11.70), number of sprouted cuttings (18.33), sprouting percentage (91.67), number of shoots (5.13), length of shoot (10.40 cm), number of leaves per cutting (21.93), diameter of shoot (2.30 mm) and maximum fresh and dry weight of shoot (3.01 g and 1.30 g respectively) was recorded in cutting treated with IBA 5000 ppm.
