摘　　要：为探究叶面施硒(Se)对燕麦籽粒硒积累和营养品质的作用,以坝莜6号、坝莜12号、白燕2号3个燕麦品种为研究对象设置田间试验,在扬花期叶面喷施不同浓度(Se1:12 g/hm^(2);Se2:36 g/hm^(2))的硒营养液(SeO_(3)^(2-)),同时以不喷硒为对照,测定灌浆期籽粒硒含量以及成熟期营养品质(氨基酸和脂肪酸)。结果表明,随灌浆时间延长,燕麦籽粒硒含量呈先升高后降低的趋势。其中,成熟期施硒各处理籽粒硒含量均在0.10~0.30 mg/kg的国家标准范围内,显著高于对照,且在Se2处理下籽粒硒含量最高,为0.16 mg/kg。与对照相比,施硒明显提高了3个燕麦品种籽粒中总氨基酸的含量,低氨基酸品种坝莜6号增加了2.13%~10.53%,高氨基酸品种白燕2号增加了7.44%~9.37%。与对照相比,施硒提高了3个燕麦品种籽粒中不同脂肪酸含量,且品种类型、硒肥浓度及二者的互作效应的影响均达到极显著水平(P<0.01)。结果说明叶面喷施硒肥能显著促进燕麦籽粒硒积累,强化籽粒氨基酸和不饱和脂肪酸的含量,其中以Se2处理效果更好。In order to explore the effects of foliar selenium(Se)application on selenium accumulation and nutritional quality in oat grains,a field experiment was conducted using three oat varieties(Bayou 6,Bayou 12,and Baiyan 2).At the flowering stage,selenium nutrient solution(SeO_(3)^(2-))with different concentrations(Se1:12 g/ha,Se2:36 g/ha)were sprayed on the leaves,and selenium-free was used as control(CK).The selenium content in grains at grain-filling stage and the nutritional quality(amino acids and fatty acids)at maturity stage were determined.The findings demonstrated that the selenium concentration in oat grains first increased and then decreased with the extension of the filling period.Specifically,at maturity stage,selenium contents of all selenium-treated treatments was within the national standard range of 0.10-0.30 mg/kg,which was significantly higher than that of the CK.The highest selenium content(0.16 mg/kg)was observed under the Se2 treatment.Compared with the CK,selenium application significantly increased the total amino acid content in oat grains of all three varieties:the content in the low amino acid varietyʻBayou 6ʼincreased by 2.13%-10.53%,while the content in the high amino acid varietyʻBaiyan 2ʼincreased by 7.44%-9.37%.Compared with the CK,selenium application increased the content of different fatty acids in grains of the three oat varieties.The influences of variety type,selenium fertilizer concentration,and their interaction effect all reached a very significant level(P<0.01).Foliar selenium spraying can significantly promote the accumulation of selenium and enhance the contents of amino acids and unsaturated fatty acids in oat grains,the effect of the Se2 treatment is better.
