Abstract
Since the seeds of rootstock ‘Torero’ for eggplant have a poor germination rate, the effects of priming processing using some promoting chemicals, such as polyethylene glycol solution, were studied. When the seeds were treated with a combination of GA3 100 mg/liter to PEG 300 g/liter for about 15 days, germination was effectively promoted. Furthermore, the practical effect of treatment persisted for at least 30 days when dried seeds were stored at 5 °C or low humidity. Although the seeds harvested in 1998 did not show exceptionally germination improved by chemical treatment only, the additional treatment of the low temperature procedure for 21 or 31 days before the chemical treatment remarkably improved germination.
