The rooting medium, types of stem cuttings, and the concentration of Benzyladenine influencing the growth of stem cuttings of water dropwort (Oenanthe javanica (Blume) DC.)

Abstract

Water dropwort, an aquatic vegetable, is cultivated and used popularly as fresh and processed vegetable in Vietnam. Propagation by stem cuttings is the most commonly used method to propagate water dropwort. Rooting medium, types of stem cuttings, and treating cuttings, with Benzyladenine at a suitable concentration are the most important factors for successful propagation. The experiment results showed that stem cuttings were the best materials for successful propagation of water dropwort. Inserting the cuttings which were treated with BA at the concentration of 5 ppm into the rooting medium including a ratio of 5/6 coconut dust and 1/6 microorganic-fetilizer resulted in a high percentage of survival cuttings (81.18%) and a high percentage of young plants (64.12%).
