ADVENTITIUS ROOTING OF PEACH CULTIVARS SEMIHARDWOOD CUTTINGS

Abstract

The aim of this work was to evaluate the rooting potential of semihardwood cuttings from peach cultivars Capdeboscq, Charme, Chimarrita, Della Nona, Eldorado, Eragil, Granada, Jubileu, Leonense, Maciel, Marfim, Ouro, Pampeano, Precocinho and Riograndense treated with indolbutiric acid (IBA) in concentration of 1000 mg dm-3, with fast immersion for 5 s. The  experiment was realized in the Embrapa -SNT Canoinhas (SC). The cuttings had been collected on march, prepared with 15 cm of length, diameter among 4 to 6 mm, while leaving one pair of leaves cut to the way in its top side. The plantation of the cuttings has been made at greenhouse with intermittent mist in seedbeds of 3 m2, containing as substrate sands average  texture remaining during 81 days in that environment. The experiment was laid out as full randomized with six replicates and 12 cuttings per experimental plot. The bigger percentages of rooting cutting were obtained with the cultivars Marfin (90.27%), Eldorado (79.16%), Maciel (76.38%) and Leonense (69.44%). The cultivars Granada, Ouro, Pampeano and Riograndense presented low rooting potential and root development.
