Effect of indolebulyric acid on the rooting of wood cuttings of peach Diamante cultivar

This study was undertaken with the major objective to evaluate the possibility of propagating peaches (Prunus persica (L.) Batsch) by wood cuttings in the Diamante cultivar. The cuttings were obtained from manually bent branches in January of 1979 and branches not bent, all of them with indolebutyric acid (IBA), in five concentrations: zero, 1000, 2,000, 3,000 and 4,000 ppm by the rapidly immersed method at the base and taken to the nursery at two different times (May and June 1979). The IBA application stimulated rooting of the peach wood cuttings of bent and not bent branches with a significant superior response of bent branches. The treatments that gave highest percentages of rooted cuttings were those from bent branches treated with 2,000 and 3,000 ppm of IBA and put in the nursery in June of 1979. Mean values for survival in these treatments were 46 and 48% respectively when rooted cuttings were measured in December of 1979.
