| 摘 要： | 向营养液中添加活性炭显著促进了豌豆植物株的生长，而未添加活性炭的栽培残液提取物则对豌豆和莴苣胚根伸长均表现出明显的抑制作用。生长抑制物质主要在花前分泌，分泌物中酸性，中性和碱性物质均具有较强的生长抑制活性。用气相色谱／质谱联用仪从根系分泌筘鉴定出苯甲酸，对羟基本甲酸，香草酸，肉桂酸，香豆酸，３，４－二羟在苯甲酸，３－５二甲羟基香豆酸等７个生长抑制物质。

| Abstract: | The addition of activated charcoal to the nutrient solution for pea culture greatly improved the growth of pea.Extracts of residual solution after pea culture significantly inhibited the elongation of pea and lettuce radicle.The exudates at vegetative stage were much more phytotoxic than those at the reproductive stage.Benzoic,cinnamic, p hydroxybenzoic,3,4 dihydroxybenzoic,vanillic, p coumaric and sinapic acids were identified from the phytotoxic acidic fraction of the root exudates. |
