“…Growers should wash chestnuts, discard floaters, and cool immediately to 0 to 0.5-1°C for storage. Ertan et al (2015) found that low temperature was the main factor that positively affected chestnut quality. Relative humidity should be as high as possible, but even still protective packaging may be needed to avoid desiccation.…”

Although many areas of the United States are suitable for chestnut (Castanea sp.) production, less than 1.0% of chestnuts are domestically produced with most U.S. orchards less than 30 years old. Furthermore, the majority of U.S. citizens are not accustomed to chestnuts as a mainstream nut crop but rather associate them with winter holidays. Because nearly all chestnuts are imported, agricultural producers have a significant incentive to expand U.S. chestnut production and command top dollar because of their crop being locally produced and potentially certified organic. With cultural and postharvest practices becoming more refined, growers are poised to seize this niche crop opportunity.

“…There is no documented difference in seed dormancy between American and Chinese chestnut-both species must undergo a dormant period of several months to germinate (Saielli et al 2012), and in both species, the seed is metabolically active during its dormant phase because chestnuts are recalcitrant seeds (Leprince, Buitnik, & Hoekstra, 1999;Roach et al, 2009). The sugar content of chestnuts under cold storage increases while starches diminish (Ertan, Erdal, Gulsum, & Algul, 2015). Differences in genes that regulate dormancy or signals that communicate dormancy to squirrels, or binding sites for regulatory molecules, are therefore less likely to be false-positives than structural or housekeeping genes.…”

Dispersal of seeds by scatter‐hoarding rodents is common among tropical and temperate tree species, including chestnuts in the genus Castanea. Backcrossed (BC) interspecific hybrid chestnuts exhibit wide variation in seed traits: as the parent species (Castanea dentata and C. mollissima) have distinct seed phenotypes and tend to be handled differently by seed dispersers, phenotypic variation in BC trees is likely due to inheritance of genes that have undergone divergent evolution in the parent species. To identify candidate genomic regions for interspecific differences in seed dispersal, we used tagged seeds to measure average dispersal distance for seeds of third‐generation BC chestnuts and sequenced pooled whole genomes of mother trees with contrasting seed dispersal: high caching rate/long distance; low caching rate/short distance; no caching. Candidate regions affecting seed dispersal were identified as loci with more C. mollissima alleles in the high caching rate/ long‐distance pool than expected by chance and observed in the other two pools. Functional annotations of candidate regions included predicted lipid metabolism, dormancy regulation, seed development, and carbohydrate metabolism genes. The results support the hypothesis that perception of seed dormancy is a predominant factor in squirrel caching decisions, and also indicate profitable directions for future work on the evolutionary genomics of trees and coevolved seed dispersers.

“…As an important foodstuff, chestnuts have high economic value, being rich in carbohydrates and low in fat; they contain (on a g/100 g dry matter basis) 75.3-86.3 g total carbohydrates, 10.3-22.8 g total sugar, 0.5-2 g total fat, and 4.9-10.9 g total protein (Ertürk et al 2006). Sweet chestnut quality is determined by external factors, such as colour, shape, size, surface blemishes and mould, which are very important in terms of consumer acceptance (Ertan et al 2015).…”

Sweet chestnut (Castanea sativa Mill.) is one of the most important species in agro-forestry and horticulture. Turkey is an important C. sativa gene centre and fruit production region. The present study aimed to measure the variations in fruit width, length, thickness and weight in four different natural C. sativa populations in Turkey and determine the loss of fruit traits due to damage by chestnut weevil (Curculio elephas (Gyllenhal, 1836)) (Coleoptera: Curculionidae). Fruits were collected from four populations (Istanbul-Bahçeköy, Çanakkale-Bayramiç, Balıkesir-Erdek and Bursa-Uludağ) of phenotypically healthy sweet chestnut trees, measurements were taken, and the fruits were classified into those damaged by C. elephas and those not. Analysis revealed significant differences among and within the populations in all fruit traits, and between the sound and damaged fruits, with the average fruit width, length, thickness and weight being 24.8 mm, 23.1 mm, 15.3 mm and 3.4 g, respectively. Bursa-Uludağ population had the highest healthy fruit ratio (70%), with some individuals in the population yielding healthy fruits at ratios > 90%. In the Balıkesir-Erdek population, however, where the percentage of damaged fruits was the highest (54%), it was determined that some trees suffered more than 90% damage in contrast to the Bursa-Uludağ population. In the fruits infested by C. elephas, the approximate percentages of loss in fruit width, length, thickness and weight were 6, 4, 7 and 30%, respectively. The fruit weight loss percentages varied between 25% and 32% among the populations.
