Produtividade de minicepas de três espécies florestais em diferentes tamanhos de tubetes

Abstract

The research objective was evaluating the productivity of ministumps of Poincianella pyramidalis, Senegalia bahiensis and Enterolobium contortisiliqumm in different sized tubes. The experiment was conducted in nursery seedling of the Centre of Agricultural Sciences, Environmental and Biological of the University Federal of Reconcavo of Bahia of Cruz das Almas. The experimental delimitation was entirely randomized (DIC) for the three experiments, containing three treatments (tubes 50, 180, 280 cm3) with 4 replicates. The seedlings used for production the mini garden were produced in commercial substrate (Vivato) fertilized with slow release fertilizer. Were produced 25 seedlings per repeating Poincianella, 20 seedlings per repeating for making the mini garden of Senegalia and 10 seedlings per repeating for mounting the mini garden of Enterolobium. The prunings occurred at 122, 80 and 61 days after sowing, respectively for Poincianella pyramidalis, Senegalia bahiensis and Enterolobium contortisiliqumm. Assessments were made every 15 days, starting 30 days after the formation of the mini garden to Poincianella and Enterolobium and 18 days to Senegalia. The Shapiro’s normality test has been applied to the data which hadn't showed normality and has been performed analysis of variance and the average test Scott- Knott at 5% probability for those who had submitted normality. The ministumps grown in tubes of 280 cm3 were the ones that had the best productions of minicuttings for the three species studied and ministumps produced in tubes of 50 cm3 showed low productivity of minicuttings.
