【 摘 要 】

This work was carried out in a greenhouse with intermittent mist out at the plant Science Department, Eliseu Maciel Agronomy College of Federal University of Pelotas (Brazil), aiming to evaluate the effect of different substratos and time of cutting on rooting of pium cuttings. Mild cuttings with 15cm length andapair of ieaves of Frontier cultivar were coilected from a commercial orchard eight years old in November 1993, January and March 1994. All cuttings were treated with indolbutiric acid (IBA) at 3000ppm concentration introducing about 1.0cm of their basal end in IBA powder and placed in tubes on isopor trays containing different substratos: washed mild sand: vermiculite of medium grains; rice husk ash and saw dust, utilized as isolated or as mixtures (1:1 v/v). Cuttings were kept on substratos for 60 days. The results demonstrated that the higher rooted cuttings percentage were obtained for cuttings collected in January and in March. The mixture of sand and saw dust gave the higher number of cuttings rooting with 68.22% and 65.99% for January and March.
