Abstract:
In recent times, the Adenium has gained prominence in the ornamental and landscape gardening because of its striking Caudex forms and flower colour. However, commercial production of these species is relatively new in crop management, especially recommended substrates for germination is not yet standardized. The goal of this experiment was to know, how different media affect seed germination and seedling production in Adenium Arabicum. Seeds of Adenium were sown in various substrates like Sand, Redsoil+Sand+FYM (2:1:1), Red soil, Perlite, Vermicompost, Redsoil+Sand+Coir compost (2:1:1), Vermiculite and Coir compost. The results of this study revealed that vermiculite had a greater germination rate (82%) and produced higher quality seedlings in terms of shoot length (5.20cm), taproot length (3.84cm), plant height (9.04cm) and caudex diameter (3.8cm). As a result, media containing Vermiculite is best suitable for Adenium Arabicum rootstocks for both better germination and seedling growth.
