Abstract

This research was carried out to establish a mass-production method and to develop ornamental Gramineae species as cash crops for famers as three species of ornamental grasses were used for seed treatment and plug production. Germination rates of Arundinella hirta were improved to 52.6% by soaking in 4% NaOCl for 60 min and 49.4% with 4% NaOH for 30 min. Germination rates of Panicum virgatum were 20.3% and 22.4% when treated with 4% NaOCl for 10 min and 2% NaOH for 60min treatment, respectively. Pennisetum alopecuroides showed germination rates higher than 98% with both 4% of NaOCl and NaOH for 60 min. When the same size of trays were used, Pennisetum showed faster plug formation in 21 and 30 days with 162 and 40 cell trays, respectively. Arundinella showed a similar trend with Pannicum in completing plug formation, those took 32, 41, and 44 days with the 162, 72, and 40 cell tray, respectively. Plug production was faster with smaller cells; however, total growing period was longer with larger cells in general.
