摘要

本研究採用洋蔥'CAL 606'品種為試驗材料，調查二種穴格（128與288穴格）與三種種植株數（每穴種植1株、2株、3株）對洋蔥鱗莖生長之影響。結果顯示128穴格培育之洋蔥，在鱗莖重、鱗莖莖徑、大球率表現顯著地大於288穴格培育之洋蔥。不同穴格間之鱗莖頸徑、莖頸比、長度/直徑(L/D)則無顯著之差異。在每穴不同種植株數結果，鱗莖莖徑隨著每穴種植株數的增加而減少；L/D隨著株數增加而增大；鱗莖之重量、鱗莖頸徑、莖頸比、大球率則無顯著之差異。

Onion cv. 'CAL 606' was used in this experiment. It was to survey the bulb growth of onions after transplanting, with two plug tray size(128 and 288 cells) and different number of plants per cell(one, two and three). The results showed that bulb weight, bulb diameter and percentage of large bulbs from seedlings of 128 cells per tray were greater than those grown in 288 cells after transplanting. Bulb ratios of onions grown from different plug tray size were not significantly different. As the number of plants per cell increased from one to three, the bulb diameter decreased, but the L/D ratio increased as the number of plants per cell increased. There were no differences in bulb weight, bulb neck diameter, bulb ratio and percentage of large bulbs between different number of plants per cell.
