本研究以北葱品種‘福葱’、‘新莊’與四季葱品種‘蘭陽1號’、‘宜蘭2號’四品種為材料，經2001年與2002年春季與夏季共四期田間試驗，探討青葱之園藝性狀，如單叢重、分蘖數、植株展幅、葱白直徑、葱白長度、葉片數目、植株高度、葉片寬度等8種性狀與耐熱性之關係。結果顯示‘新莊’與‘福葱’為耐熱品種，‘蘭陽1號’與‘宜蘭2號’屬熱敏感品種。植株高度、葉片寬度可作為田間高溫指標，卻無法作為青葱耐熱指標。單叢重、分蘖數、葱白直徑三性狀適合作為耐熱指標。

Two heat tolerant varieties, 'Fu-tsun' and 'Hsinchuang', and two heat sensitive varieties of green onion (Allium fistulosum L.), 'Lanyang #1', and 'Yilan #2', were used for establishing selection criteria of horticultural traits associated with heat tolerance. Field evaluations of plant weight per hill and per stem, tiller number, diameter and length of false-stem, plant width, leaf number, plant height, green leaf length, and leaf diameter were conducted in the spring and summer crops in 2001 and 2002.Comparison of spring and summer crops, amounts of plant weight per hill and tiller number increased in the heat tolerant varieties were higher than those in the heat sensitive varieties. Diameter of false-stem were higher in the heat tolerant than those in the heat sensitive varieties for both of spring and summer crops. We suggest that plant weight per hill, tiller number and diameter of false-stem can be used as selection criteria for heat tolerance in green onion.
