The effect of a colloidal solution of Cu,Zn-nanoparticles on pro-oxidative/antioxidative balance and content of photosynthetic pigments and leaf area of winter wheat plants of steppe (Acveduc) and forest-steppe (Stolichna) ecotypes was investigated in drought conditions. It has been shown that Cu,Zn-nanoparticles decreased the negative effect of drought action upon plants of steppe ecotype Acveduc. In particular, increased activity of antioxidative enzymes reduced the level of accumulation of thiobarbituric acid reactive substances (TBARS) and stabilized the content of photosynthetic pigments and increased relative water content in leaves. Colloidal solution of Cu,Zn-nanoparticles had less significant influence on these indexes in seedlings of the Stolichna variety under drought.
研究了铜锌纳米颗粒胶体溶液对草原生态型（Acveduc）和森林草原生态型（Stolichna）冬小麦植株在干旱条件下的促氧化/抗氧化平衡、光合色素含量及叶面积的影响。结果表明，铜锌纳米颗粒降低了干旱对草原生态型Acveduc植株的负面影响。特别是，抗氧化酶活性的提高降低了硫代巴比妥酸反应性物质（TBARS）的积累水平，稳定了光合色素含量，并提高了叶片的相对含水量。在干旱条件下，铜锌纳米颗粒胶体溶液对Stolichna品种幼苗的这些指标影响较小。
