摘要

在常压条件下,用乙烯Fitomag合成抑制剂处理Stenley品种李子果实时,果实过氧化物酶和多酚氧化酶活性的变化取决于贮藏条件和贮藏时间、果实在贮藏过程中的代谢过程、品种的特殊性和贮藏方法。两种方法保存后,过氧化物酶活性逐渐降低,多酚氧化酶活性逐渐升高。在Fitomag法贮藏的果实中,这些酶的值比在普通气氛中贮藏的要低。与通常的气氛相比,较低的氧化还原过程强度有利于用这种方法保存水果的品质。SBA常规和微量元素处理与对照之间以及品种之间也存在本质差异。

Modificarea activității peroxidazei și a polifenoloxidazei în fructele de prun în funcție de influența SBA Reglalg, microelementelor (B, Zn, Mn, Mo) și a metodelor de păstrare
When storaging the plum fruits of the varieties Stenley under normal atmospheric conditions and by the method of treating them with the synthetic inhibitor of ethylene Fitomag, the modification of peroxidase and polyphenol oxidase activity in fruits depended on the conditions and duration of storage, metabolic processes course in fruit during storage, the particularities of the varieties and their storage methods. The gradual decrease in peroxidase activity and the increase in polyphenol oxidase activity occurred in the case of fruit preservation by both methods. In the fruits storaged by the Fitomag method, the values of these enzymes were lower compared to those in the ordinary atmosphere. The lower intensity of the redox processes has beneficially influenced the preservation of the quality of the fruits preserved by this method compared to the usual atmosphere. There were also essential differences between the control and the variants treated with SBA Reglalg and microelements, as well as between varieties.
