摘要
以“雨花三号”桃果实为试材,研究了1-甲基环丙烯(1-MCP)处理后对桃果实乙烯生物合成途径和细胞壁降解相关酶的影响。结果表明:1-MCP处理能够延缓果实后熟软化进程,降低了桃果实乙烯释放量,并抑制了果实快速软化阶段的ACC氧化酶(ACO)的活性;对多聚半乳糖醛酸酶(PG)和α-L-阿拉伯呋喃糖苷酶(α-AF)活性均表现一定的抑制作用。
Peach cultivar ‘yuhuasanhao' was used to investigate the effect of I-MCP on ethylene biosysthesis and cell wall hydrolases in this paper. The results showed that 1-MCP treatment made ethylene production decrease and that inhibited ACC oxidase activity in the stage of peach fast-softening. It also did something to inhibit polygalacturonase (PG) and α-L-Arabinofuranosidase (α-AF) activity.
