“…This could indicate that under high air humidity, fractures represented a pathway for water uptake (Hovland and Sekse, 2004a). Water uptake through the pedicel of fruit in which cuticles were scored to simulate fractures or minor cracks was measured potometrically (Hovland and Sekse, 2004b). These fruit accumulated more water via the pedicel than unscored fruit, implying that the scoring resulted in increased transpiration.…”

Rain-induced fruit cracking in sweet cherries can be a major problem. In the Pacific Northwest United States, due to high labor costs, when fruit cracking exceeds 25% at harvest, fruit are not picked. Oregon State University Horticulture and Pharmacy Faculty have collaborated in producing and patenting a novel, elastic, organic biofilm, SureSeal, which significantly reduced sweet cherry fruit cracking by up to 250% in Milton Freewater, Oregon and Loftus, Norway. Formulations of SureSeal are hydrophobic and consist of a copolymer of complex carbohydrates, phospholipids and calcium. Collaborative research undertaken over three years throughout the Pacific Northwest and overseas found that two applications of 1% SureSeal applied at straw color, and again ten days later, reduced fruit cracking consistently when compared to untreated control fruit. In Norway, fruit cracking was reduced from 24.6 to 9.8% when trees were treated with SureSeal in combination with plastic ground covers and a preharvest fungicide (fenhexamid). Furthermore, studies throughout Oregon and Idaho found that SureSeal resulted in significantly (P<0.001) higher total soluble solids (TSS) and increased Stem Pull Force (g) (retention force between the pedicel and the fruit) than untreated control fruit. In 2008, 'Bing' fruit had higher TSS both before (18.5°Brix) and after (18.9°Brix) two weeks of regular atmosphere storage at 2°C than untreated control fruit (17.4 and 17.2°Brix, respectively). In Norway, 1% Biofilm increased TSS to 21.4°Brix compared to untreated control fruit (18.6°Brix). Two applications of 1% Biofilm applied at straw color and again ten days later has the potential to significantly reduce fruit cracking, accelerate maturity by significantly increasing TSS levels, and increase stem pull force. The concurrent reduction in fruit firmness observed may be a function of maturity but, in all instances, fruit firmness still exceeded the minimum standard of 250 g mm-1 .

“…Long et al (2009) suggest that some of the inconsistency associated with sprays is the inconsistent level of wax components in fruit skin, and it has been established that no new cuticle formation occurs in the later stages of fruit growth but becomes thin and under stress as fruit enlarges allowing for increased skin conductance to water Knoche et al, 2004). Additionally, fruit can develop microscopic cuticular fractures during the last two weeks of their growth period (Hovland and Sekse, 2004) further reducing the natural barrier to water uptake (Alkio, 2012). It is this loss of integrity that is thought to promote the visible cracking that is associated with rainfall.…”

This study was designed to confirm the efficacy of anti-transpirant sprays on reducing fruit cracking in cherry, and to evaluate the impact on fruit quality at harvest and during post-harvest storage. In the study, it was observed that there were differences in the rate of natural cracking depending on the amount of precipitation, but there were inconsistencies in the differences. In some trials, the amount of precipitation has no effect on the rate of cracking, but generally the increase in the amount of precipitation has increased the rate of cracking. It has been determined that there is a significant reduction in cracking rate due to spray applications. Sprays consistently had minimal effect on fruit quality overall. Assessments of fruit post-harvest highlighted that all fruit, treated and untreated, exhibited similar behaviour during storage.
