ENRAIZAMENTO DE ESTACAS CAULINARES DE ALECRIM (ROSMARINUS OFFICINALIS)

Abstract

Rosemary is an exotic plant that is used for aromatic and medicinal purposes, with a growing demand for the production of essential oil and recently increasing use as an ornamental plant in landscaping. Thus, it was proposed to evaluate the rooting of rosemary stem cuttings as a function of different doses of growth stimulator. The treatments were T0: 0 mL L-1 plant-1 (control); T1: 2 mL L-1 plant-1, T2: 4 mL L-1 plant-1; T3: 6 mL L-1 plant-1; T4: 8 mL L-1 plant-1, the trial was carried out in the greenhouse of the Instituto Federal Goiano - Campus Ceres, using a randomized block design with five replications. The experimental unit consisted of ten cuttings and the variables analyzed were survival rate (SR), length of the largest root (LR), number of roots (NR) and plant height (AP). The treatments did not differ statistically, so the use of biostimulants is not necessary for the rooting of rosemary stem cuttings.
