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.
