Environments for rooting of guava trees multiplied by softwood cuttings or mini-cuttings

Abstract

The goal of this study was to evaluate highmoisture saturation environments for rootingcuttings from guava. The experiment was carriedout in randomized complete block design infactorial scheme composed by guava tree cultivars(Paluma and Cortibel 6), types of cuttings(softwood cuttings and minicuttings), androoting environments (conventional chamberwith intermittent nebulization and minichambers constituted of plastic containers). Fourrepetitions were used and the experimental plotswere composed by ten softwood cuttings or minicuttings.Rooting of ‘Paluma’ ranged between77.5 and 97.5 % and of ‘Cortibel 6’ between2.5 and 57.5%, depending on the environmentand the propagation technique.
