摘要

新鮮與經80℃乾燥之四季蔥葉片水溶性浸出液，其EC值及總酚類化合物含量隨濃度之增加而增加，然pH值則隨濃度增加而下降。四季蔥或北蔥之新鮮葉片在20 g/100ml與經80℃乾燥在6 g/100ml以上之浸出液濃度，對北蔥、萵苣與蘿蔔種子有抑制發芽、胚根、胚軸生長與延長發芽日數之效應，顯示隨著濃度之增加能產生自毒與相剋之作用。

A decrease of pH value and an increase in EC and the amount of total phenolic compounds was found by increasing concentrations of imbibed for fresh and 80℃ dried leaves of green onion cv. Shy-Zih Stong. The imbibed concentration at 20 g/100 ml for fresh and 6 g/100 ml for dried green onion leaves of cv. Shy-Zih Stong and Pei-Stong inhibited seeds germination of green onion cv. Pei-Stong, lettuce and radish, also delayed the average germination period and inhibited the radicles and hypocotyls growth. Results showed that the autotoxicate and allelopathic effects varied with the concentration of exudated from green onion leaves.
