| 摘 要： | 以不同产地的丹参种子为材料,研究了不同浓度(0、0.005、0.01、0.02、0.03、0.04g/ml)核桃叶水浸液对丹参种子萌发和幼苗生长的影响.结果表明,低浓度(0.005、0.01、0.02 g/ml)的核桃叶浸提液对不同产地丹参种子的萌发有明显的化感促进作用；随着水浸液浓度的提升,其对受体的促进作用逐渐减弱、消失,甚至表现为抑制作用.在试验浓度范围内,核桃叶水浸液对丹参种子的幼苗根长、苗高、相对电导率、可溶性糖含量及可溶性蛋白含量均表现为促进作用,最佳作用浓度为0.02 g/ml.核桃叶水浸液可以在某种程度上促进丹参种子的萌发和幼苗的生长.

| Abstract: | Taking the Salvia miltiorrhiza Bunge seeds from different region as test objects,this paper examined the allelopathy effects of different concentrations(0,0.005,0.01,0.02,0.03,0.04 g/ml)water extracts of walnut leaf on seed germination and seedling growth of Salvia miltiorrhiza Bunge.The results showed that low concentrations(0.005,0.01,0.02 g/ml) of walnut leaf aqueous extract stimulated seed germination significantly.With the concentration of the aqueous extract increased,the stimulating effects of all th... |
