【摘要】 测定了加拿大一枝黄花水浸提液对辣椒、番茄、萝卜、长梗白菜和小麦等五种经济作物种子萌发和生长的影响。结果表明:(1)高浓度的加拿大一枝黄花水浸提液对几种作物种子萌发和生长有明显的抑制作用,而低浓度下则对萝卜、长梗白菜和番茄的种子生长有一定的促进作用;(2)加拿大一枝黄花茎叶部分水浸提液的抑制作用要强于地下部分。更多还原

【Abstract】 The seed germination and growth of five crops including Capsicum annuum, Lycoperiscum esculetum, Raphanus sativus, Brassica chinensis var. communis and Triticum aestivum were determined by water extract of Solidago Canadensis. The main results were as follows:1) High concentration of water extract of Solidago canadensis could restrain the seed’s germination and developing, while low concentration of the water extract could accelerate developing seed of Raphanus sativus, Brassica chinensis var. communis and Lycoperiscum esculetum; 2) the restraining influences of the maceration extract from the organs above ground were stronger than those from the underground.更多还原
