Estimulación del enraizamiento de estacas con extractos de Salix fragilis, Plantago lanceolata y Aloe vera

Abstract

The present work aims to evaluate the effect of rooting aqueous extracts of willow (Salix fragilis L), plantago (Plantago lanceolata L), aloe (Aloe vera L) and the combination of extracts of P. lanceolata and S. fragilis on stakes of rosemary, (Rosmarinus officinalis L). The rooting capacity of the natural extracts is compared with that of the commercial product ANA (naphthalene acetic acid). The test was carried out outdoors in artificial substrate with periodic record of temperature and rainfall. The rooting stimulation was measured four months after implantation, evaluating quality, number of roots, number of callus per stakes and fresh weight of branches, expressing the rooting effects in percentage. It is hypothesized in this work that the extracts of S. fragilis, A. vera and P. lanceolata significantly promote the rooting of cuttings and that the exposure to the combined extracts has synergistic effects on the quality of roots developed and on the percentage of Rooting The results indicate that the rooting with the extract of P. lanceolata was similar to that of the control with distilled water, being less the rooting effects in the treatment with the ANA and with the extract of A. vera. Inhibitory effects were observed by exposure to S. fragilis extract and its combination with extracts of P. lanceolata, possibly due to the use of willow extract in a high concentration. The verification of these results is recommended by evaluating in future studies, different concentrations of rooting and extraction methods.
