在大田条件下,于R5期对不同品质类型大豆品种叶片喷施SOD摸拟物(SODM)、氯化胆碱(Choline chloride,Cc)和2-N,N-二乙氨基乙基己酸酯(Diethyl aminoethyl hexanoate,DTA-6)3种植物生长调节剂,成熟收获后测定籽粒中氨基酸组分含量。结果表明:SODM、Cc、DTA-6均降低了不同品种类型大豆的氨基酸总量,其中高蛋白品种黑农35氨基酸总量降幅(0.50%～1.03%)最小,而双高品种垦农4号氨基酸总量降幅(2.53%～4.67%)最大。SODM、Cc、DTA-6对不同品质类型大豆氨基酸组分比例均有影响,三者均提高了高蛋白品种黑农35的丙氨酸、缬氨酸和异亮氨酸含量。
Under field conditions, the leaves of different quality soybean varieties were sprayed with SOD mimic (SODM), choline chloride (Cc) and 2-N, N-diethylaminoethylhexanoate (Diethyl aminoethyl hexanoate, DTA-6) three kinds of plant growth regulators, the content of amino acids in the kernel after ripening was measured. The results showed that SODM, Cc and DTA-6 all reduced the total amino acids of different types of soybean, of which the high protein variety Yinnong 35 had the smallest decrease (0.50% ~ 1.03%), while the double high variety Kennong 4 Total amino acid decline (2.53% ~ 4.67%) the largest. The effects of SODM, Cc and DTA-6 on the proportions of amino acids in different quality soybean varieties all increased, and the contents of alanine, valine and isoleucine in high-protein variety Heinong 35 were all increased.
