Enraizamento de mini estacas da cultivar Cingapura de Pimenteira-do-Reino.

Abstract

Black Pepper (Piper nigrum L.) is important in the economic environment because of its commercial value. The spreading medium is the form commonly used on a large commercial scale. The objective was to investigate the rooting of the cuttings in relation to the commercial product Clonex (indolebutyric acid) and two substrates used. The experiment was conducted in a greenhouse under sombrite, located at Embrapa Amazônia Oriental / Belém-Pa. The treatments were arranged in a 2 x 5 factorial scheme: (two substrates: (sand and vermiculite) x five diluted dosages of commercial Clonex product (AIB compound) (25, 50,100,200 mg.L-1 ) with 10 treatments, 10 replications totaling 100 stakes, each plot being a stake, the data were submitted to statistical analyzes of variance, tests of comparison of means and regression analysis.The results obtained did not respond significantly to the rooting for the studied variables: the root length, the root number, the number of the highest sprouting, the length of the highest sprout, showing that the use of the commercial product was not necessary for the rooting of the cultivar under study. roots and shoot. In the rooting conditions for cultivating Singapore the use of the commercial clonex product (AIB) did not show satisfactory results because only with the substrates the cuttings responded to the induction and root formation.
