Abstract

The need for patchouli is increasing with the increase of population and the development of the cosmetics industry. The supply of healthy and of high production patchouli cutting is necessary to ensure the optimum of production. The purpose of this study was to determine the effect of NAA concentration and the right parts source of cuttings and the interaction between the two on the growth of patchouli. The study was conducted in the Experimental Field and Plant Physiology Laboratory of the Faculty of Agriculture, Universitas Syiah Kuala, Banda Aceh, in January to April 2019. The study used a factorial randomized block design with a 4x3 factorial pattern with three replications. NAA was applied using Growtone, a brand with an NAA concentration of 3%. Factors studied were Growtone concentration at 0, 4.0, 8.0, and 12.0 g L water, and parts of stem source (shoots, middle, and base). The results showed that the best growth of patchouli cuttings was at Growtone concentration of 4.0 g L water, while the best shoot length and leaf area was found in the treatment of Growtone concentration of 12.0 g L water. Meanwhile, the best growth of patchouli cuttings was found in the stem taken from the shoot’s part. There was no significant interaction between NAA concentration and the source of the different parts of stem on the growth of patchouli.
NAA浓度及茎部不同部位对广藿香生长的影响
随着人口的增长和化妆品工业的发展,对广藿香的需求也在不断增加。健康、高产的广藿香切花供应是保证广藿香最佳生产的必要条件。本研究旨在探讨NAA浓度和扦插部位源对广藿香生长的影响及其相互作用。该研究于2019年1月至4月在班达亚齐Syiah Kuala university农业学院实验田和植物生理学实验室进行。本研究采用4 × 3阶乘随机区组设计,共3次重复。NAA采用Growtone品牌,NAA浓度为3%。研究的影响因素为0、4.0、8.0和12.0 g L水和部分茎源(芽、中、基部)的Growtone浓度。结果表明,当Growtone浓度为4.0 g L水处理时,广藿香扦插苗生长最佳,而当Growtone浓度为12.0 g L水处理时,枝长和叶面积最佳。同时,广藿香插枝生长最好的部位是茎部。NAA浓度与茎部不同来源对广藿香生长无显著交互作用。
