In vitro Multiplication of the Pitcher Plant Sarracenia Purpurea

Abstract

The aim of the current research was to find the best plant growth regulators for the multiplication of Sarracenia purpurea. Murashige and Skoog medium (MS) was prepared with macronutrients and micronutrients at 1/3 strength, full strength vitamins, supplemented with 30 g/l sucrose and 5 g/l phytagel and autoclaved. After cooling 0.5 mg\l α-naphthaleneacetic acid (NAA), 5 mg\l 6-benzyladenine (BA) or 0.5 mg\l NAA + 3 mg\l BA were added. Young S. purpurea plants were selected and transferred to media with or without plant growth regulators and cultured for 12 weeks. At the end of this time frame number of roots, root length (cm) and number of shoots were evaluated and differences were analysed by the analysis of variance and interpreted using the Tuckey test. The largest number of roots grew in medium supplemented with 0.5 mg\l NAA but the the absence of plant growth regulators increased their length. The best conditions for shoot multiplication were provided by supplementing 1/3MS with 5 mg\l BA.
