Rooting and growth of planting stock and seedlings of Echeveria elegans at different concentrations of índole-3-butyric acid (AIB) are evaluated. Foliar planting stock was divided into 100 units immersed in 0, 50, 100 and 200 ppm of AIB solution for 30 minutes. Each planting stock was subdivided into four transparent gerbox boxes with wet vermiculite totaling 25 planting stocks. The boxes were closed and maintained in BOD for 60 days at 25 ºC, under a 12-h photoperiod and approximately 116 µmol.m-2.s-1 light intensity. The concentration of 100 ppm of AIB had the best results for the analyzed variables: number of roots (NR), number of leaves (NF), stem diameter (EC), length of the longest root (CMR), length of the largest leaf (CMF), total fresh matter (MFT) and total dry matter (MST). Concentration of 200 ppm had phytotoxic effect on the leaf planting stock.Downloads
