摘　　要：研究以α-生育酚含量水平不同的两个大豆品种北丰9（高）和龙选1号（低）为试验材料，在大豆生殖生长期利用光照培养箱以三个温度处理（28～34℃、22～28℃、16～22℃），研究不同温度对大豆茎、叶、荚皮、籽粒维生素E含量影响。结果表明，随温度升高，大豆茎中α-生育酚、γ-生育酚和维生素E总含量降低（P〈0.01），叶片中α-生育酚和维生素E总含量降低（P〈0.01），籽粒中γ-生育酚、δ-生育酚和维生素E总含量降低（P〈0.01），而籽粒中α-生育酚增加（P〈0.01）。中等温度（22～28℃）更有利于大豆荚皮中δ-生育酚和VE总含量积累，而低温（16～22℃）不利于α-生育酚和γ-生育酚积累。高温条件能提高α-生育酚从叶、茎和荚皮向籽粒中转化运输率（P〈0.01），有利于大豆籽粒中α-生育酚含量积累。The paper was conducted to determine the effects of temperature in stems, leaves, pod wal s and seeds under three temperature regimes （28-34 ℃, 22-28 ℃ and 16-22 ℃） with two soybean cultivars, Beifeng9 and Longxuan1, differing inα-tocopherol content. Results showed that with the increase of temperature,α-tocopherol,γ-tocopherol and total vitamin E contents in soybean stems,α-tocopherol and total vitamin E contents in soybean leaves, γ-tocopherol, δ-tocopherol and total vitamin E contents in soybean seeds were decreased （P〈0.01）, whileα-tocopherol content in soybean seeds were increased （P〈0.01）. Medium temperature （22-28 ℃） was the most advantageous for accumulation of δ-tocopherol and total VE contents in soybean pod wal s, while low temperature （16-22 ℃） was not advantageous for accumulation of α-tocopherol and γ-tocopherol contents. High temperature improved transport rate of theα-tocopherol from leaves, stems and pod wal s to seeds （P〈0.01）, which resulted in increasing the accumulation of theα-tocopherol content in soybean seeds.
