Abstract
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.
