Abstract

新鮮或經80℃乾燥之‵新竹′四季蔥葉片水溶性浸出液之pH、EC值及總酚類化合物含量,隨浸出液濃度之增加而降低pH,增加EC值及總酚類化合物含量。‵桃園三號′四季蔥與‵桃園選育一號′北蔥之新鮮葉片在20g/100ml及30g/ml與經80℃乾燥在6g/100ml及9g/100ml等濃度之浸出液,對北蔥、萵苣與蘿蔔等種子具有抑制發芽、抑制胚根及胚軸生長、延長發芽日數等作用,並隨著浸出液濃度之增加,呈現明顯的自毒與它毒之相剋作用。Decreasing in pH and increasing in EC and contents of total phenolic compound in response to increasing in the concentrations of exudates of fresh and 80℃ dried leaves of green onion cv. Shy-Zih Stong were found. Inhibition of seed germination and growth of radicle and hypocotyl, and delay of germination of green onion cv. Pei-Stong, lettuce and radish were found in the exudates of fresh and dried leaf of green onion cv. Shy-Zih Stong and Pei-Stong at concentration of 20~30g/100ml and 6~9g/100ml, respectively
