| 摘 要： | 本工作研究了5℃低温吸胀对大豆和豌豆整粒种子或种子碎粒呼吸代谢的影响。结果表明:①在5℃吸胀0～1 5min,大豆种子碎粒 EMP 途径和 TCA 循环对总呼吸的相对贡献先增加后降低,并低于对照,豌豆种子碎粒 EMP 途径和 TCA 循环占总呼吸的比例均较高。②与整粒种子先在25℃再转入5℃吸胀的处理相比,若种子先在5℃再转入25℃吸胀(5～25处理),两类种子去子叶胚通过细胞色素途径的呼吸明显降低。③整粒种子经5℃吸胀后转入25℃萌发96～144h,细胞色素氧化酶和琥珀酸脱氢酶活性均显著低于对照(25℃吸胀)。据此队为,呼吸代谢平衡失调是低温吸胀造成种子吸胀冷害的重要原因之一。
