摘　　要：为揭示喷硒对燕麦硒积累的影响,并评价筛选喷硒后燕麦产量和品质综合性状优良燕麦品种,以24份燕麦品种为材料,设置3个喷施浓度(亚硒酸钠用量为0、80、160g/hm^(2)),抽穗期进行叶面喷硒。结果表明,燕麦成熟期叶片硒含量随喷硒浓度提高增幅最大,其次为籽粒。喷硒降低24份燕麦籽粒硒含量变异水平。喷硒下,籽粒硒含量差异最大,根硒含量差异最小。叶面喷施80g/hm^(2)的亚硒酸钠时,籽粒硒含量最高的品种可达0.30mg/kg;喷施160g/hm^(2)亚硒酸钠时,24份燕麦品种籽粒硒含量均超多数文献提到的食物或可食材料硒限量标准(0.300mg/kg)。喷硒也会影响籽粒蛋白质、脂肪和β-葡聚糖含量的变异程度。在叶面喷施80g/hm^(2)亚硒酸钠时,燕麦产量与未喷硒均无显著差异;燕麦籽粒硒含量与脂肪、β-葡聚糖含量存在显著正相关,相关系数分别为0.63和0.42;GYT双标图基于产量,兼顾硒、蛋白质、脂肪和β-葡聚糖含量,24份燕麦品种综合值排名前5位的依次为品燕1号、Banner、OA1576-4、白燕10号和品燕2号。In order to reveal the effects of spraying selenium on the selenium accumulation in oats,and evaluate and screen excellent comprehensive traits oats varieties based on yield and quality after spraying selenium,24 oats varieties were used as research materials,three spraying concentrations were set(sodium selenite dosage was 0,80,160g/ha)to spray on leaves at heading stage.The results showed that selenium content in oats leaves had the highest increase with increasing spraying selenium concentration at mature stage,with selenium content in grains in turn.The spraying selenium decreased the variation degree of grain selenium content.Under the same selenium concentration,the differences of selenium contents in grains among 24 oats varieties were the greatest,however,and the least in roots.When 80g/ha sodium selenite was sprayed,the highest selenium content in grains was 0.30mg/kg,but when the spraying concentration was 160g/ha,the grain selenium contents of 24 oats varieties all exceeded the limitations for selenium content in foods or edible materials from most of different literatures(0.300mg/kg).The variation levels of grain protein,fat andβ-glucan contents were also changed by spraying selenium.When spraying 80g/ha sodium selenite,the yields of oats had no significant difference compared with the treatment of spraying 0g/ha;correlation analysis showed that there was a significant positive correlation between selenium content and contents of fat andβ-glucan,with correlation coefficients 0.63 and 0.42,respectively.GYT biplot analysis based on yield and considering grain selenium,protein,fat andβ-glucan contents showed that the top five oat varieties were Pinyan 1,Banner,OA1576-4,Baiyan 10 and Pinyan 2 in turn.
