碩士 === 國立中興大學 === 園藝學系 === 92 === The influence of plug tray cell size and number of seedlings per cell on leave number、plant height and bulb diameter have shown that onion seedlings in 128 cell tray with single-seedling per cell had greater size, and bulbs were matured one week earlier than other treatments. The onion seedlings transplanted from 128 cell tray were greater in yield、bulb weight、bulb diameters、bulbing ratios、higher percentage of large bulbs than those raised in 288 cell tray. There were no significantly differences between onion seedligs raised in 128 and 288 cell on bolting percentage、bulb neck diameters、bulb length/diameter（L/D）and number of scale. The L/D of bulbs increased as the number of plants per cell increased, but there were no significant differences on bolting、bulb weight、bulb neck diameter、bulb diameter、number of scale、dormant sprouts and percentage of large bulbs. Onions raised in 288 cell tray with three-seedlings per cell had the highest weight loss and rotten percentage during storage in year 2002. There were no significant interactions between cell volume and years as well as number of plants per cell and years.
