Ascorbic acid content and redox-enzymes activities of AA system are determined in four population of Dasypyrum villosum adapted to live in different environments. In D. villosum from the driest and warmest environment (Pachino), AFR reductase and AA peroxidase have activities lower than in the other populations. The results point out the role of AA peroxidase as the main "scavenger" of the H2O2 produced by cell metabolism.
在适应不同环境生存的四个簇毛麦种群中，测定了抗坏血酸系统的抗坏血酸含量和氧化还原酶活性。在来自最干燥和最温暖环境（帕基诺）的簇毛麦中，AFR还原酶和抗坏血酸过氧化物酶的活性低于其他种群。结果表明抗坏血酸过氧化物酶作为细胞代谢产生的过氧化氢的主要“清除剂”的作用。
