- 摘要:
- 以结球甘蓝种子为试材，采用正交实验设计，研究了不同磁场强度、不同作用时间、不同浸泡时间的稳恒磁场处理对种子萌发的影响效果，并测定了磁场处理种子萌发后幼苗的相关生理生化指标。结果表明：磁场处理可以有效提高种子萌发效果，最佳影响幅度可达100%以上，湿种子相比于干种子效果明显；在各个影响因素中，磁场强度为主要影响因子；作用时间、浸泡时间主次顺序因发芽指标不同而不同；磁场强度1 000 GS、处理10 min、浸泡8 h是提高种子活力的最佳组合，磁场强度过大反而抑制萌发效果；磁场处理可以加快种子萌发中物质间代谢变化、增加酶活性、增强种子抗逆性，从而影响种子萌发达到壮苗齐苗的效果。
- Abstract:
- Taking cabbage seeds as test material，by orthogonal experimental design，effect of various factors，different magnetic field intensity，different time，different soaking time of steady magnetic treatment on seed germination were studied，and magnetic treatment seedlings after germination related physiological and biochemical indexes were determined.The results showed that，magnetic field treatment could effectively improve seed germination，the best impact rate of up to 100% or more.Among the various factors，the magnetic field strength was the main influencing factor.The role of time，soaking time were the primary and secondary order for germination index varies.Magnetic field strength 1 000 GS，treatment 10 min，soaking 8 h was the best combination in terms of improved seed vigor.Too large the magnetic field intensity inhibited germination.Magnetic field could speed up germination substance metabolic changes，increase activity，enhance seed resistance，affect seed germination to achieve strong seedling.
