Applied diamines and polyamines inhibited the incorporation of radioactively labeled leucine and uridine into trichloroacetic acid-insoluble material in apple (Malus domestica Borkh, cv Golden Delicious) fruit tissue. The inhibitory effect was in general more pronounced with the higher molecular weight amines. Putrescine at 5 millimolar inhibited leucine incorporation by 37% and uridine by 44%. Spermidine and spermine at the same concentration inhibited uridine incorporation by 60%. The polyamines at concentrations between 0.1 and 1.0 millimolar inhibited leucine incorporation by 55 to 90%. The inhibitory effect of 0.1 to 10 millimolar polyamines on dark- and wound-induced senescence or ethylene production, is discussed in the light of interference with macromolecular synthesis.
应用二胺和多胺可抑制放射性标记的亮氨酸和尿嘧啶掺入苹果(Malus domestica Borkh,cv Golden Delicious)组织的三氯乙酸不溶物中。一般来说,分子量较高的胺的抑制作用更为明显。5 毫摩尔腐胺可抑制亮氨酸掺入 37%,尿嘧啶掺入 44%。同样浓度的亚精胺和精胺可抑制尿嘧啶掺入 60%。多胺在 0.1 至 1.0 毫摩尔浓度下可抑制亮氨酸掺入 55%至 90%。本文讨论了 0.1 至 10 毫摩尔多胺对暗诱导和伤诱导衰老或乙烯生成的抑制作用,认为这与干扰大分子合成有关。
