研究了1-甲基环丙烯（1-MCP）的结构类似物1-戊基环丙烯（1-PentCP）对香蕉果实采后成熟和衰老的抑制作用。AAA集团巴西）。结果表明：1-PentCP能推迟香蕉果实乙烯释放高峰和呼吸高峰的出现时间，延缓果实软化和变色，抑制果实可溶性固形物、可溶性糖和1-氨基环丙烷-1-羧酸（ACC）含量的增加，抑制ACC合成酶（ACS）和ACC氧化酶（ACO）活性，抑制MaERS 1和MaERF 1基因的表达。另外，1.2 μL/L1-PentCP通过抑制乙烯生物合成相关酶的活性和乙烯受体基因的表达，延缓香蕉的成熟衰老。有人建议，1-PentCP可能是一个有前途的候选人作为一个给定的乙烯抑制剂的乙烯作用开始之前应用的实际用途。
The aim of this study was to investigate the inhibitory effect of 1-pentylcyclopropene (1-PentCP), a structural analogue of 1-methylcyclopropene (1-MCP), on postharvest ripening and senescence of bananas fruit (Musa acuminata L. AAA group cv. Brazil). The results showed that 1-PentCP was effective in postponing the occurrence time of ethylene production peak and respiration rate peak, delaying the softening and color change, inhibiting the increasing of soluble solids, soluble sugar, and 1-aminocyclopropane-1-carboxylate acid (ACC) content; inhibiting the activities of ACC synthase (ACS) and ACC oxidase (ACO); and suppressing the expression of MaERS1 and MaERF1 in bananas. In addition, 1.2 μL/L 1-PentCP was found to be most effective in delaying ripening and senescence process of bananas by inhibiting the activities of enzymes involved in ethylene biosynthesis and gene expression of ethylene receptors. It is suggested that 1-PentCP could be a promising candidates for practical use as a given ethylene inhibitor applied before the onset of ethylene action.
