Successful Production

Fruit quality is a factor of considerable significance for successful production and it depends on a number of parameters that need to be recognized and understood to make informed decisions about which cherries we need to be growing today and tomorrow, in order to maximize our opportunities and remain profitable in the future. In a context of climate change and diversification of agricultural production practices, sweet cherry actors are turning to varietal innovation Boubennec 24 to work on criteria such as cracking, firmness, fruit size, fruit properties and tree traits, in order to achieve high quality production.

Climacteric Fruit

Abscisic acid (ABA) plays a major role in promoting ripening in sweet cherry, a non-climacteric fruit. Exogenous application of ABA has been performed to study fruit ripening and cracking, but this growth regulator is not used for commercial production. To determine the potential of this growth regulator to improve sweet cherry fruit quality, ABA canopy spraying was assayed in four cultivars. Canopy spraying of S-ABA significantly: (1) enhanced sweet cherry fruit color in ‘Glenred’, ‘Lapins’ and ‘Bing’ cultivars, but not in ‘Royal Rainier’ (a bi-colored cultivar), and (2) decreased fruit size and firmness in ‘Lapins’, ‘Bing’ and ‘Royal Rainier’. Seasonally reproducible effects were seen in ‘Lapins’ (mid/late-maturing) but not in ‘Glenred’ (early-maturing). Canopy spraying of nordihydroguaiaretic acid (NDGA) decreased color and increased fruit size in ‘Lapins’, but not in ‘Glenred’. Direct application of ABA on fruits attached to the tree, without application to the foliage, increased ‘Lapins’ fruit color without reducing size. These results suggest a localized fruit response to exogenous ABA application on fruit color development, but that a decrease in fruit size may be due to the effects of exogenous ABA on the tree canopy foliage.

‘Cristalina’ and ‘Skeena’ sweet cherry cultivars (Prunus avium L.) on Gisela 6 (Prunus cerasus × Prunus canescens) rootstock planted in 2005 were maintained since 2006 in a randomly blocked split-split plot experimental design with six blocks of two irrigation frequency main plot treatments within which two cultivar subplots and three soil management sub-subplots were randomly applied. The focus of this study was the growth, yield, and fruit quality response of sweet cherry to water and soil management over three successive fruiting seasons, 2009–11, in a cold climate production area. The final 2 years of the study period were characterized by cool, wet springs resulting in low yield and yield efficiency across all treatments. Soil moisture content (0- to 20-cm depth) during the growing season was often higher in soils that received high-frequency irrigation (HFI) compared with low-frequency irrigation (LFI). HFI and LFI received the same amount of water, but water was applied four times daily in the HFI treatment but every other day in the LFI treatment. Consequently, larger trunk cross-sectional area (TCSA) and higher yield were found on HFI compared with LFI trees. Soil management strategies involving annual bloom time phosphorus (P) fertigation and wood waste mulching did not affect tree vigor and yield. Increased soluble solids concentration (SSC) occurred with LFI. Decreased SSC occurred with delayed harvest maturity in trees receiving P fertigation at bloom. The largest fruit size was correlated for both cultivars with low crop loads ranging from 100 to 200 g fruit/cm2 TCSA. Overall cool, wet spring weather strongly affected annual yield and fruit quality, often overriding cultivar and soil and water management effects.

To determine the potential of this growth regulator to improve sweet cherry fruit quality, ABA canopy spraying was assayed in four cultivars.

Seasonally reproducible effects were seen in ‘Lapins’ (mid/late-maturing) but not in ‘Glenred’ (early-maturing).

We conducted audience surveys at three major peach producer meetings across the United States. We found that the relative importance assigned to fruit quality and tree traits by producers varied across producers’ end markets. Fresh peach producers indicated fruit flavor and size were the most important fruit quality traits, whereas processed peach producers viewed fruit size, fruit firmness, and absence of split pits as being the most important traits for a successful peach cultivar. These results have potential to ensure that peach breeding programs are consonant with fresh and processed peach producers’ needs for fruit and tree traits.

Abstract Agricultural production is both strongly affected by climate change and a major contributor to climate change, with agriculture and land use change accounting for around a quarter of total global emissions of greenhouse gases. Agricultural production benefits from substantial government support, costing around US$600 billion per year worldwide. These subsidies clearly affect greenhouse gas emissions by influencing the composition and location of output, and production practices, but no rigorous quantification of these impacts have been available to date. This article fills this void. Overall, we find small impacts of agricultural support programs on output and hence on emissions. Abolishing support altogether thus would do little to reduce global emissions from agriculture. In fact, paradoxically, it could even increase emissions. A repurposing of support towards incentives for more resource-efficient and climate-smart forms of production needs to be considered if this support is to contribute to climate change mitigation, adaptation and food security.

Abstract This chapter focuses on the fundamentals of pruning sweet cherry orchards. The fundamentals of training and pruning contemporary sweet cherry orchards usually incorporate plant materials or techniques that promote: early fruiting for a more rapid return on investment; optimization of light interception and distribution, with minimal intra-canopy shading; greater precision in, and/or simplification of, canopy development for balancing yields with fruit size and quality, as well as ease of teaching to less experienced labor forces; and systematic processes for annual renewal of fruiting wood to maintain consistent yields of high fruit quality as trees age.

The study involving 5 cherry cultivars was conducted in 2015–2016. The varieties ‘Techlovan’, ‘Summit’, ‘Sylvia’, ‘Kordia’ and ‘Regina’ were planted in 2010 in the Experimental Orchard of the Department of Pomology in Warsaw-Wilanów on GiSelA5 rootstock. The aim of the study was to evaluate the production value and dessert fruit quality as well as health proprieties of the tested cultivars’ fruits and select the most valuable ones. It was shown that the varieties differed in fruit set and yielding as well as fruit quality (i.e. fruit size, firmness, soluble solid content, acidity) and health benefits (i.e. polyphenol, anthocyanin, and ascorbic acid content). ‘Techlovan’ trees had the lowest yield, but their fruits were of high quality. ‘Kordia’ and ‘Regina’ also provided high quality fruit with high total polyphenol content. In contrast, the ‘Sylvia’ cultivar had a high yield, but the fruit obtained from it was of poor quality. All tested cultivars had similar vitamin C content.
