Indole butyric acid in the rooting of physalis cutting

Abstract

Physalis angulata L. grows as a wild plant in tropical areas of America, its center of origin being undetermined, it is believed that the plant originated in South American countries. In propagation by cuttings, auxins are necessary for the formation of adventitious roots. The objective was to evaluate different dosages of IBA in the rooting development of Physalis cuttings. Apical herbaceous cuttings of Physalis with 10 cm in size were used, submitting them in basal contact in a mixture of IBA with talc in the concentrations: 1000 mg.Kg-1, 2000 mg.Kg-1, 3000 mg.Kg-1 and 4000 mg.Kg-1, and untreated cuttings as a control, staked in tubes with a capacity of 200 mL with substrate soil + sand (2:1), in mini greenhouses with intermittent nebulization. The experimental design was in randomized blocks (DBC), with 5 treatments in four replications, with each experimental unit composed of 10 cuttings. After 60 days from the beginning of rooting, the percentage of rooting was evaluated; bud length; root length; green and dry mass of leaves; green and dry mass of roots. IBA improved rooting and development of Physalis angulata L.
