摘要

叢枝菌根菌披衣處理種子之北蔥種苗生長六週，使用阿拉伯膠與PVP為披覆劑之植株性狀皆較其他處理組顯著表現佳。在施用介質與叢枝菌根菌菌砂不同比例處理下，萌芽率無顯著差異，菌根菌菌砂與介質比值為1：20之菌根感染率為最高，植株性狀顯著高於其他處理組。菌根菌處理對經3、6天淹水處理之北蔥種苗生長二週，菌根菌處理者可減少葉片黃化率9.3～9.9%，增加11.0～14.5%植株生長速率。

Using Arabic gum and PVP to coat the Welsh onion seed with arbuscular mycorrihiza yielded the best seedling growth after six weeks. The ratios of medium and mycorrihizal sand didn't affect the germination rate. The root infection percentage of the medium and mycorrihzal sand ratio was 1:20 with the highest infection percentage compared to the others. The mycorrihizal treatment of Welsh onion seedling after three and six days flooding had the highest shoot fresh weight, average growth rate, leaf sheath diameter, and sheath length compared to the other treatments during two weeks recovering period. The mycorrhizal treatment reduced the yellow leaf percentage about 2.3~6.2% and enhanced the plant growth rate about 11.0~14.5%.
