Enraizamento in vitro de <i>Anthurium andraeanum</i> Lindl. cv. Eidibel e aclimatização com fungos micorrízicos arbusculares

Abstract

The aim of the present study was to evaluate A. andraeanum in vitro rooting and acclimatization with arbuscular mycorrhizal fungi (AMF). In order to induce rooting, the consistence and ionic strenght of MS medium modified (5,71 µM de NAA) were tested: solid MS; liquid MS; solid half-strenght MS and liquid half-strength MS. After 60 days, plants were acclimatized in association with the AMF Gigaspora albida, Glomus etunicatum, Acaulospora longula, multiple inoculum or without AMF (control treatment). The liquid nutritive medium containing the complete concentration of MS salts induced better plant development, specially with regard to root number. Mycorrhization reduced the acclimatization impact, favoring water and phosphorus absorption, as well as plant growth, specially those associated with multiple inoculum.
