Produ̧ão de mudas de lamiaceae para o cultivo hidropnico: Qualidade de enraizamento

Abstract

Apex and basal cuttings of Lamiaceae plants (Mentha crispa L., Mentha piperita L. and Salvia officinalis L.) were submitted to rooting assay. The effects of water, H3BO3, KH2PO4, ZnSO 4 and KNO3 solutions on the formation of adventitious roots were studied in greenhouse conditions. The root morphology parameters were determined after the rooting processes. Salvia officinalis did not produce adventitious roots under the experimental conditions. Apex or basal cuttings showed similar rooting development. The root volume and length were more influencied by KNO3 and H3BO3 solutions than diameter and root surface area.
