以黄瓜品种南水1号、超市1号和南抗1号贮藏5a的陈种子为试材，研究不同固体基质引发对老化黄瓜种子活力的影响。结果表明：固体基质引发处理可以改善老化黄瓜种子的膜透性，减轻膜脂过氧化作用，提高种子活力，促进其萌发，蛭石和珍珠岩引发处理均可以不同程度地提高老化黄瓜种子的萌发率和萌发速度，降低种子浸出液的相对电导率、可溶性糖含量及丙二醛含量，提高SOD活性；椰糠引发处理的黄瓜老化种子萌发特性及生理指标与对照差异不显著。

In order to study on aged seed vigor of cucumber(Cucumis sativus L.),taking 5 years old cucumber seeds‘Nanshui No.1’,‘Chaoshi No.1’,‘Nankang No.1’as experimental materials, this paper studies the effects of priming by different solid matrix on aged seed vigor of cucumber.The results showed that the solid matrix priming treatment could improve the membrane permeability, reduce membrane lipid per-oxidation, increase seed vigor and promote its germination.Generally, vermiculite and perlite could enhance the germination percentage and germination ratio of cucumber seeds,reduce the relative electric conductivity,soluble sugar content and malondialdehyde(MDA) content in seedling leaves,and increase superoxide dismutase(SOD)activity in different extent. However,there was no significant difference between the coconut husk and the control in germination characteristics and physiological indexes of aged cucumber seeds.
