Ophiopogon sp. is a perennial herb native to China. It has been introduced to some tropical countries as an ornamental plant species. This plant has a good local and foreign market as potted plants and cut foliage. As these plants are very slow growing, obtaining leaves with required length and quality are difficult. The aim of this study was to investigate the performance of two plant growth hormones and potting media on the growth of Ophiopogon sp. to aid in improving it. Pot experiments were carried out to test the effect of plant growth hormones (Indole acetic acid and Benzyl amino purine) and potting media (Coir dust: compost: sand 1:1:1 and leaf mould: soil: sand 1:1:1) on the above and below ground growth. Three experiments were conducted using the two potting media, experiment 1 and experiment 2 with individual application of IAA and BAP respectively and experiment 3 with IAA and BAP in combination. In experiment 1, there was a significant increase (p 0.05) in fresh weight with potting medium 2 and leaf length with potting medium 1, at 100 mg/l IAA. In experiment 2, the highest fresh weight (in potting medium 2) was obtained at 75 mg/l BAP. Leaf length was significantly higher in all the BAP treated plants compared to the untreated control. In Experiment 3, highest fresh weight and highest leaf length was observed at IAA with BAP combination of 1:1. Out of the three experiments, the combination of BAP and IAA volume in 1:1 gave the best results than when used alone. Potting medium 2 showed a significantly higher performance in fresh weight of plant and leaf length than potting medium 1.
