Micropropagation and Acclimatization of <i>Monstera deliciosa</i> Liebm. ‘Thai Constellation’

Abstract

Monstera deliciosa Liebm. ‘Thai Constellation’ is a variegated variety of M. deliciosa belonging to the family Araceae, which has become a new favorite in the foliage plant market. However, limited studies exist on its propagation, and growers have difficulties in achieving large-scale production. This study aimed at developing an efficient protocol for the micropropagation of M. deliciosa using SETIS™ temporary immersion bioreactors. Furthermore, we aimed at evaluating the role of a novel biostimulant (IQ Forte) in the acclimatization of M. deliciosa. Significant differences were observed among the different treatments, showing higher multiplication rates under TIS conditions as compared to the semi-solid control. Adjusting immersion parameters also showed benefits in improving multiplication rates. The novel biostimulant (IQ Forte) did not provide significant gains in growth of M. deliciosa ‘Thai Constellation’ during acclimatization.
