Abstract
Concentrations of 0.3 w/v of carboxy methylcellulose (CMC) and 0.3 w/v of hydroxyethyl methylcellulose (MHEC) was found to be easiest formed pellets and appropriated in water solubility period. The pelleted seeds with 0.3 w/v of MHEC had the lowest pore friability, at 4.09%. The pelleted seeds with 0.1 w/v of CMC and 0.1 w/v of MHEC formed fragile pellets with a high percentage of friability. The pelleted seeds with each pelleting method showed significantly higher germination than the unpelleted seeds. The pelleted seeds with 0.3 w/v of MHEC had significantly higher root length than the unpelleted seeds. Therefore, pelleted seeds with 0.3 w/v of MHEC as a binder with 40 g of calcium sulfate per 10 g of seeds showed the most suitable formula for hybrid cucumber variety ‘YokKaow’ seeds
