Effect of Different Cultivars and Cutting Positions on Growth of Kalmegh (Andrographis paniculata (Burm. f.) Nees) โสมนันทน์ ลิพันธ์

Abstract

The study was conducted to investigate the effects of stem cutting position along the mother plants on growth cutting of different Kalmegh cultivars. A split plot experiment in a randomize completely block design with four replications was employed. The main plot was three Kalmegh cultivars (Pachinburi, Phisanulok 5-4 and Phichit 4-4) and sub plot consisted of three types of position of stem cutting, namely basal, middle, and top cutting, respectively. The results obtained indicate that the significant differences on growth characteristics may have occurred due to variation in varietal characteristics. Prachinburi had the highest root and shoot growth significantly different (P≤0.05) from Phisanulok 5-4 and Phichit 4-4. The position of stem cuttings along the mother plants significantly affected on growth of Kalmegh. Stem cuttings from the top had the highest growth and was significantly different from stem cuttings collected from the middle and base of the mother plants. In addition, there were not significantly interaction between cultivars and cutting positions. However, top cutting position from Prachinburi cultivar can be recommended for propagation Kalmegh using stem cuttings.
