绿色生物量的大麦幼苗表现出统计学显着较高的活性超氧化物歧化酶（SOD）和过氧化氢酶（CAT）在采样I（在植物发育阶段DC 29）相比，后来的采样II（DC 31）。品种、年份及各因子的交互作用对所研究的抗氧化剂活性有显著影响。在试验期间（2005-2007年），品种塞巴斯蒂安的平均SOD活性（486 U.g-1）显著高于品种Malz（416 U.g-1干物质）和品系KM 1910（418 U.g-1干物质）。后两个品种之间没有统计学显著差异。不同品种间过氧化氢酶活性差异不显著。显着较高的CAT活性在采样I记录的平均年份和地点的品种塞巴斯蒂安和无壳线KM 1910（935和907 U.g-1）相比，品种马尔茨（675 U.g-1）。我们可以说，在生长阶段DC 29期间采集的年轻春大麦植物的绿色生物量是实验过程中（2005-2007）酶过氧化氢酶和超氧化物歧化酶的重要来源。
Green biomass of young barley plants exhibited statistically significant higher activity of superoxide dismutase (SOD) and catalase (CAT) at sampling I (in the phase of plant development DC 29) compared to the later sampling II (DC 31). Significant effects of varieties, years and interactions of the studied factors on the activity of the studied antioxidants were determined. During the experiment period (2005-2007), the variety Sebastian provided statistically significant higher average SOD activity (486 U.g-1) versus the variety Malz (416 U.g-1 dry matter) and line KM1910 (418 U.g-1 dry matter). No statistically significant difference was recorded between the latter two varieties. Average catalase activity of the varieties did not show any significant difference. Significantly higher CAT activity in the sampling I was recorded on average of years and locations in the variety Sebastian and hull-less line KM1910 (935 and 907 U.g-1) compared to the variety Malz (675 U.g-1). We can state that green biomass of young spring barley plants taken during the growth phase DC 29 was a significant source of enzymes catalase and superoxide dismutase in the course of the experiment (2005-2007).
