摘要
研究了瑞香狼毒(Stellera chamaejasme L.)提取液对藜(Chenopodium album L.)、马齿苋(Portulaca oleracea L.)、益母草(Leonurus heterophyllus Sweet.)、籽粒苋(Amaranthus hypochondriacus L.)、鸡冠花(Celosia cristata L.)等5种植物种子萌发和幼苗生长的影响。结果表明,瑞香狼毒化感作用是存在的,并且瑞香狼毒的水、乙醇、丙酮提取液对种子萌发的影响不同。3种瑞香狼毒提取液对益母草幼苗生长的影响强度一直最大,除瑞香狼毒水提取液对马齿苋幼根生长和籽粒苋幼苗生长略有促进外,其他溶剂提取液对其他几种植物苗根、幼芽和幼苗鲜重均有明显抑制作用。
The extracting solution from Stellera chamaejasme L.was used to study its effects on seed germination and seedling growth of five plants,Chenopodium album L.,Portulaca oleracea L.,Leonurus heterophyllus Sweet.,Amaranthus hypochondriacus L.and Celosia cristata L..The results revealed the existance of allelopathy of S.chamaejasme L.,which had different levels of affection on seed germination when using distinctive extracting solvents such as distilled water,ethanol and acetone.All the three kinds of extracting solution from S.chamaejasme L.had significant inhibition effect on the seedling growth of L.heterophyllus Sweet.There was obvious inhibitive influence on the fresh weight of shoot roots,plumules and seedlings of Chenopodium album L.,L.heterophyllus Sweet and Celosia cristata L.,except the slight increase on the radicle growth of Portulaca oleracea L.and seedling growth of Amaranthus hypochondriacus L.by the extracting solvent of distilled water.
