“…Different results among studies including the present study could partially be due to different cultivar used and inconsistent 1-MCP treatment and storage conditions. Ethylene is known to increase activity of phenylalanine ammonia lyase, which is a key enzyme involved in earlier step of phenolic biosynthesis [43], which has been shown to increase flavonoid content in apples [44]. Our results of decreased total phenolic after storage indicate that the phenolic synthesis and degradation during storage might involve multiple factors, in addition to ethylene.…”

Scab (Venturia inaequalis) is a very serious disease for apples causing up to 80% of loss in yield but there are only a few studies on postharvest quality of scab-resistant cultivars. In this study we evaluated the effect of 1-methylcyclopropene (1-MCP) on fruit quality, total phenolic content, and antioxidant capacity after storage of four scab-resistant cultivars and compared to a standard cultivar, "Golden Delicious." In general, ethylene production and respiration rates significantly differed among cultivars, between control and 1-MCP-treated fruits, and between storage duration regimes. 1-MCP treatment retarded fruit softening and lowered juice pH but storage effect on soluble solids and acidity depended on cultivar and 1-MCP treatment. Total phenolic content was significantly affected by storage duration and 1-MCP treatment. Antioxidant capacity of the four scab-resistant cultivars was either similar to or significantly higher than that of "Golden Delicious" with the 1-MCP-treated fruits having significantly higher antioxidant capacity than the nontreated fruits after storage. Our results clearly show that the quality of four scab-resistant cultivars was comparable to that of "Golden Delicious" and 1-MCP effect differed among cultivars. These differences need to be considered in developing storage regime to minimize quality deterioration during long-term storage. IntroductionThe hazardous effects of pesticides on human health and the environment have contributed to the introduction of cultivars with effective resistance genes to major plant diseases. Yield losses from fungal diseases are significant in most apple producing countries worldwide. Apple scab, caused by the fungus Venturia inaequalis, is one of the most destructive diseases of apples throughout the world, causing up to 80% loss in yield without chemical intervention, which could include multiple classes of fungicides applied up to 22 times during the growing season [1]. In 1944 Hough, from University of Illinois, was the first to identify the scab-resistant gene in Malus floribunda [2]. Since 1944, additional scab-resistant genes have been identified in other apple species [3]. In 1948, three US universities (Purdue, Rutgers, and Illinois, PRI) formed a research team to develop apple cultivars resistant to scab, utilizing the gene [3]. In recent years, several apple cultivars containing have been introduced into commercial production from the PRI program, including "Dayton," "Prima," "Priscilla," and "Jonafree" [4]. Among the most promising introductions are "WineCrisp" [5], "CrimsonCrisp" [6], "Pixie Crunch" [7], and "GoldRush" [8]. In addition to the scab-resistant apple cultivars released by the PRI breeding program, several cultivars have also been released by breeding programs at Cornell University in NY, by Agriculture Canada, and by the National Institute of Agronomic Research in Angers, France, and Consorzio Italiano Vivaisti in Italy, and Breeding Initiative Niederelbe in Germany [9].Despite the introduction of several apple scab-resis...

“…The seasonal availability of fruit can be extended by polycultural edible landscaping that spreads fruit harvest over 7-8 months (Dana 2001), which is also important for urban biodiversity habitat (Colding 2007) and synergistic with urban beekeeping. Additional season extension can be achieved through the use of climate-controlled storage that can preserve certain fruits for 3-11 months (Thompson 2010;Leja et al 2003), and through preservation via canning, freezing, dehydrating, pickling, pressing, fermenting, or creating value-added products for retail sales. Decentralizing fruit production, which is presently concentrated in one region in the US, where over half of U.S. fruit is produced in California (USDA 2006), would also reduce the dependency of cities on distant sources of food that are susceptible to a variety of potential supply shocks (Fraser et al 2005).…”

Introducing urban food forestry: a multifunctional approach to increase food security and provide ecosystem services

We examine the potential role of perennial woody food-producing species (''food trees'') in cities in the context of urban sustainable development and propose a multifunctional approach that combines elements of urban agriculture, urban forestry, and agroforestry into what we call ''urban food forestry'' (UFF). We used four approaches at different scales to gauge the potential of UFF to enhance urban sustainability and contribute to food security in the context of urbanization and climate change. First, we identified 37 current initiatives based around urban food trees, and analyzed their activities in three categories: planting, mapping, and harvesting, finding that the majority (73 %) only performed one activity, and only 8 % performed all three. Second, we analyzed 30 urban forestry master plans, finding that only 13 % included human food security among their objectives, while 77 % included habitat for wildlife. Third, we used Burlington, Vermont as a case study to quantify the potential fruit yield of publicly accessible open space if planted with Malus domestica (the common apple) under nine different planting and yield scenarios. We found that 108 % of the daily recommended minimum intake of fruit for the entire city's population could be met under the most ambitious planting scenario, with substantial potential to contribute to food security even under more modest scenarios. Finally, we developed a Climate-Food-Species Matrix of potential food trees appropriate for temperate urban environments as a decision-making tool. We identified a total of 70 species, 30 of which we deemed ''highly suitable'' for urban food forestry based on their cold hardiness, drought tolerance, and edibility. We conclude that substantial untapped potential exists for urban food forestry to contribute to urban sustainability via increased food security and landscape multifunctionality.

“…The oxidative stress is imposed as reactive oxygen species, superoxide ( ) and hydrogen peroxide (H 2 O 2 ) accumulate, resulting in metabolic disorder due to protein and nucleic acid oxidation and lipid peroxidation, which may be used as a maturity or stress indicator [5]. Therefore, whole or processed plant tissue with high antioxidant capacity presents a greater potential for tolerance to abiotic stresses such as cold [6,7] and extension of postharvest storage life [8].…”

--Introduction. Films act as semi-permeable gaseous barriers capable of maintaining fruit postharvest quality; thus coatings consisting of non-traditional sources may represent an alternative tool for producers. The objective of our work was to investigate the effect of a galactomannan coating on postharvest quality and physiology of 'Tommy Atkins' mangoes. Materials and methods. Physiologically mature mangoes were divided into four lots and stored for 16 d. Control uncoated fruits (lot 1) were stored at ambient temperature (25°C), the second lot was uncoated and refrigerated (14°C), the third lot was coated and stored at ambient temperature, and the fourth lot was coated and refrigerated. Fruit were analyzed for physicochemical quality parameters, antioxidant enzymatic activity and lipid peroxidation. Results and discussion. Control fruit (lot 1) lost almost twice the weight of uncoated refrigerated (lot 2) and coated mangoes at both temperatures (lots 3 and 4); the fruit of lot 1 softened faster. Regarding the antioxidant enzymes, the activity of superoxide dismutase decreased throughout storage without statistical differences between treatments and catalasic activity was significantly inhibited under refrigeration. At ambient temperature, coating delayed the catalasic activity peak to day 12, which was coincident with the lowest lipid peroxidation degree, evidencing the association of free radical production and scavenging mechanisms. The galactomannan coating was efficient in reducing weight loss and delaying softening; thus, it maintained quality of 'Tommy Atkins' mangoes for a longer period of time than the control treatment during storage at ambient temperature. Refrigeration (14°C) enhanced the performance of the galactomannan coating; it was effective in slowing down the metabolism and delaying softening to day 12.Brazil / Mangifera indica / fruits / storage / postharvest technology / coating / refrigeration / antioxidants / keeping quality / quality Effet d'un enrobage de galactomannane sur les paramètres de qualité physico-chimique et la physiologie de la mangue en post-récolte.Résumé --Introduction.
