摘要
选用了安徽省淮南片小麦区试5个生态点的10个小麦品种（系）为试验材料,测定其全麦粉脂肪氧化酶（LOX）活性。研究了基因型、环境及基因型×环境互作对小麦LOX活性的影响。结果表明,全麦粉LOX活性的变幅为4.27-8.94 nkat.g-1,平均值为6.61 nkat.g-1,LOX活性的基因型和环境差异均达到极显著,基因型效应大于环境及基因型与环境互作效应。同时,选用皖麦48等10个小麦品种（系）为试材,测定其LOX活性等9个品质性状,分析了小麦籽粒LOX活性与若干品质性状的关系。结果表明,全麦粉LOX活性与小麦粉LOX活性呈极显著正相关,与水溶性戊聚糖含量呈显著正相关,小麦粉LOX活性与水溶性戊聚糖含量和总戊聚糖含量呈显著正相关。讨论了脂肪氧化酶在小麦品质改良中的利用等问题。
Ten wheat varieties were sown in five locations of Huainan field trial in Anhui Province to investigate the effects of genotype and environment on the lipoxygenase（LOX） activity of wheat.Results：The LOX activity of wholemeal range from 4.27 to 8.94 nkat·g-1,average 6.61 nkat o g-1.Genotype and environment both have highly significant influence on the LOX activity,and genotype effect is higher than the effects of environment and genotype × environment interaction.Meanwhile,another ten wheat varieties or lines,including Wanmai 48,et al,were selected as materials to determine LOX activity and other 8 quality traits,and the relationships of LOX activity with some wheat quality traits were analyzed.Results show LOX activity of wholemeal is positively correlative（extremely significant） with flours,and with water-soluble pentosan（significant）.The LOX activity of flour is positively correlative（significant） with water-soluble pentosan and total pentosan content.The utilization of LOX in the improvement of wheat quality is discussed.
