1-Methylcyclopropene on Fruit Quality of Se-Enriched Grape (Vitis vinifera L.) during Shelf Life Period

Abstract

Selenium (Se) deficiency in humans could be improved by biofortification of food with selenium, 1-Methylcyclopropene (1-MCP) treatment is beneficial for the non-sulfur storage of fresh fruit. This study investigated fruit quality of table grape (Hutai No.8) with foliar Se fertilizer at maturity, and fruit quality changes of table grape during shelf life stages that caused by postharvest 1-MCP treatment in 2016 and 2017. The results showed that foliar Se fertilizer application significantly increased Se content in grape berries at maturity, and the raised rate were 43.09% and 33.24% compared to that of control in 2016 and 2017 respectively, meanwhile it increased the nutritional components in grape berries, including soluble proteins, soluble sugars, Vitamin C, total soluble solids, proanthocyanidin content and so on, and decreased the titratable acidity content. During shelf life stages, 1-MCP application decreased the decay number of grapes, and SE + 1-MCP treatment had the most excellent fruit quality among all treatments in two consecutive vintages. In conclusion, Se fertilizer application could increase Se content in grape berries, also improved the fruit nutritional and health care values at maturity. 1-MCP application could delay the process of ripening and senescence for Se-enriched grape and maintaining the postharvest quality of table grape during shelf life stages, it allows us to market the fruit at a more advanced ripening stage without quality loss.

The Effects of 1-Methylcyclopropene Treatment on the Fruit Quality of ‘Idared’ Apples during Storage and Transportation

“…The 1-MCP could be applied both pre [16,17] and postharvest [18,19] as a treatment being non-toxic, stable over time and improving the quality of the products. In spite of the fact that it is applied mainly for apples, it may be used also for other fruit and vegetables, but the role of ethylene in ripening and senescence processes may differ, depending on the product, so also responses to 1-MCP are various [20].…”

1‐MCP combined with laser microporous film packaging maintains the quality and prolongs the storage period of Xiahei grapes

“…The CEL content of immature fruits is low, and CEL activity in immature fruits increases significantly in the later stages of fruit ripening and softening. It has previously been shown that 1‐MCP treatment can significantly inhibit CEL activity in Niagara grapes (Liu et al ., 2022b), Kyoho grapes (Leng et al ., 2022), and the Cabernet Sauvignon winegrape (Zhu et al ., 2020). We found that S‐MAP generated by LMF effectively suppressed respiration and enhanced the inhibition of CEL activity when it was combined with the 1‐MCP treatment.…”
