摘要

本研究的目的是评估硅(Si)在0°C保存35天的杏(prunus armeniaca var Ghorban-e-Maragheh)果实中增加酚库和抗氧化活性的潜力。与对照相比，外源Si (5 g/L)预处理显著降低了果实质量损失率(%)和果实腐烂率。采后施硅提高了苯丙氨酸解氨酶活性和总酚含量，降低了过氧化氢和丙二醛含量，提高了果实抗低温胁迫的能力。因此，硅可能被推荐用于延长水果的储存寿命和保持水果的品质。

Effect of postharvest silicon application on phenolic content and antioxidant activity of apricot (prunus armeniaca) fruits

The objective of this study was to evaluate the potential of silicon (Si) application to increase the pool of phenols and antioxidant activity in apricot (prunus armeniaca var Ghorban-e-Maragheh) fruits stored at 0°C for 35 days. Exogenous Si (5 g/L) pre-treatment significantly decreased fruit mass loss (%) and decay of fruit compared with the control. Postharvest Si application raised phenylalanine ammonia-lyase activity and total phenolic, reduced hydrogen peroxide and malondialdehyde content because of an enhancement of catalase activity, and led to increase the fruits ability to better withstand stressful cold impacts. Therefore, Si may be recommended for increasing storage life and maintaining fruit quality.

期刊介绍： Technology is an increasingly crucial input in the industrialisation and development of nations and communities, particularly in the current era of globalisation, trade liberalisation and emphasis on competitiveness. The shared technologies and innovations of today are giving birth to the radically different agrifood industries and communities of tomorrow. There is mounting evidence that investments in postharvest research and infrastructure yield high rates of return that are comparable and often higher than investments in on-farm production alone.
