摘要
为促进枸杞种子的萌发，探究接触辉光放电等离子体（CGDP）对枸杞种子萌发的影响及最佳处理工艺。以枸杞种子为研究对象，考察在不同处理时间、电压及电解质条件下CGDP对枸杞种子萌发的影响。在单因素实验的基础上，以种子发芽率、发芽指数、活力指数为指标，采用响应面优化处理种子工艺，通过种皮形貌观察与接触角测定，初步探讨了CGDP对种皮结构和性质的影响。结果表明：处理种子的最佳条件为处理时间15 min、电压550 V、电解质Na,2,SO,4,，种子萌发率最高时为95.56%；处理后种皮变得平整、纹理模糊，种子亲水性增强；幼苗叶片中叶绿素含量提升。分析结果可知，辉光放电等离子体可通过改变种皮结构对枸杞种子的萌发及生长产生促进作用。
Abstract
In order to promote the germination of ,Lycium barbarum, seeds, the ,Lycium barbarum, seeds were treated by contact glow discharge plasma (CGDP), the effects of CGDP on germination were explored under different treatment time, voltages, and electrolyte conditions. The seed treatment process was optimized by response surface optimization design based on seed germination rate and vigor indexes. The effects of CGDP on the structure and properties of the seed coat were preliminarily studied through the detecting changes in the morphology and the contact angle of the seed coat. The results showed that the optimized conditions for seed treatment were 15 min, voltage 550 V, Na,2,SO,4, electrolyte, and the highest seed germination rate was 95.56%. After treatment, the seed coat becomes flat, the texture is blurred, and the hydrophilicity of the seeds is enhanced; the chlorophyll content in the leaves of seedlings increases. Therefore, glow discharge plasma treatment can promote the germination and growth of, Lycium barbarum, seeds.
