The effects of presowing seed treatment with cold plasma (CP) on seedling growth during the first two vegetation seasons and their ability to synthesize phenolic compounds and photosynthetic pigments were compared in seedlings from seven spruce half‐sib families. Seeds were treated with atmospheric dielectric barrier discharge plasma for 1 and 2 min. The results revealed that CP treatment‐induced changes in the tested morphometric and biochemical parameters were strongly dependent on the genotype. The family 477 most positively responded to CP treatments and displayed accelerated growth, combined with a strong increase in pigment and total phenolic content. CP treatment was least effective in families 541, 577, and 599, whereas the response in families 457, 463, and 548 was ranked as intermediate.

挪威云杉对冷血浆种子处理的长期反应：对基因型的影响

比较了七个云杉半同胞族幼苗中前两个植被季节预冷种子（CP）播种对幼苗生长的影响及其合成酚类化合物和光合色素的能力。用大气电介质阻挡放电等离子体处理种子1分钟和2分钟。结果表明，CP治疗引起的形态和生化参数变化强烈依赖于基因型。477族对CP处理的反应最为积极，并显示出加速的生长，同时色素和总酚含量也大幅增加。CP治疗在541、577和599家族中效果最差，而在457、463和548家族中的反应为中等。
