USE OF A ROOTING AGENT IN THE VEGETATIVE PROPAGATION OF BANANA (Musa paradisiaca L.) HARTON CLONE UNDER THERMAL CHAMBER CONDITIONS

Abstract

The objective in this work was to determine the effect of different doses of the rooting agent Root-Hor® in the multiplication of suckers of the Harton clone (bellaco plantain) under thermal camera conditions in the province of Padre Abad, Aguaytía, Peru. A thermal chamber 3 m wide x 5 m long and 1.8 m high was built, lined with transparent plastic, and in the rooting beds, compost was used as a base, forming a layer of 10 cm, followed by phosphate rock was sprinkled all over the bed and finally a 40 cm thick layer of sawdust was added. Corms of healthy mother plants were selected, with an average weight of 2 kg, from which the central growth point was eliminated by making a cone cut 4 cm deep in each corm, which were disinfected with a solution of 5% sodium hypochlorite for 3 minutes, then they were treated with the Root-Hor® rooting agent according to the doses studied (0 ml / 100 L, 50 ml / 100 L, 100 ml / 100 L, 150 ml / 100 L and 200 ml / 100 L), finally they were placed in the rooting beds, inside the thermal chamber, showing that the application of 150ml / 100L of Root-Hor® achieved 8.2 suckers / corm, 330.4 g of weight / suckling, 118.2 cm of sucker height, 4 cm diameter of sucker, 20.4 roots / sucker and 25 cm of root length, surpassing the other applications of Root-Hor® and the control, showing efficiency in the vegetative propagation of the Hartón clone under thermal chamber conditions.
