Keyword:  紫茉莉 月见草 水提液 化感作用;
Abstract: 为研究紫茉莉果实水提液对月见草的化感作用,分别用浓度为0.025g/mL、0.05g/mL、0.1g/mL紫茉莉果实水提液处理月见草种子,测定其种子的发芽势、发芽率、发芽指数、活力指数和幼苗生长状况,分析紫茉莉果实水提液对月见草种子萌发和幼苗生长的影响。结果表明,紫茉莉果实水提液浓度为0.025g/mL时,月见草种子的发芽势、发芽率、发芽指数和活力指数均达最高;紫茉莉果实水提液浓度为0.05g/mL、0.025g/mL时,提高了月见草幼苗的鲜重、苗高,但抑制了其根系的生长。紫茉莉果实水提液可促进月见草种子萌发,提高月见草幼苗的鲜重、苗高,但会抑制其根系的生长。
