The apple variety, ‘Honeycrisp’ has been extensively planted in North America during the last two decades. However, it suffers from several agronomic problems that limit productivity and postharvest quality. To reduce losses, new information is needed to better describe impact of crop load on fruit quality a desert environment major region where expansion occurring. Here, 7-year-old trees M9-Nic29 rootstock (2.5 × 0.9 m) were hand thinned five different loads [from 4.7 16.0 fruit/cm 2 trunk...
Significant interest exists in engineering the soil microbiome to attain suppression of soil-borne plant diseases. Anaerobic disinfestation (ASD) has potential as a biologically-regulated disease control method; however, role specific metabolites and microbial community dynamics contributing ASD mediated is mostly uncharacterized. Understanding trajectory co-evolutionary processes leading syntrophic generation functional during necessary prelude predictive utilization this management...
'Soggy breakdown' (SB) is an internal flesh disorder of 'Honeycrisp' apple (Malus × domestica Borkh.) fruit that occurs during low temperature storage. The a chilling injury (CI) in which visible symptoms typically appear after several weeks storage, but information about the underlying metabolism associated with its induction and development lacking. metabolic profile tissue from wholly healthy brown tissues SB was characterized using gas chromatography-mass spectrometry (GC-MS) liquid...
Sweet cherries ( Prunus avium ) destined for traveling to export markets must retain fruit and stem quality 2 5 weeks postharvest. This 2-year study evaluated commercially sorted packed sweet cherry cultivars (Chelan, Black Pearl, Bing, Regina, Skeena) outcomes following 4 of storage at −0.6 ± 0.5 °C or 4.4 in modified atmosphere (MA) bags. Cultivar-specific influences on physiochemical included pedicel retention force, firmness, color, soluble solids content, titratable acidity A comparison...
Superficial scald is a physiological disorder of apple fruit characterized by sunken, necrotic lesions appearing after prolonged cold storage, although initial injury occurs much earlier in the storage period. To determine degree to which transition cell death an active process and specific metabolism involved, untargeted metabolic transcriptomic profiling was used follow peel tissue over 180 d storage. The metabolome transcriptome destined develop began diverge from where controlled using...
'Honeycrisp' is an apple cultivar that susceptible to soft scald, a chilling injury expressed as necrotic patches on the peel. Improved understanding of metabolism associated with disorder would improve our scald and contribute developing more effective management strategies for storage. It was expected specific gene expression metabolite levels in peel be linked risk at harvest and/or time points during cold
Summary Diplodia pinea (syn. Sphaeropsis sapinea ) is known as a major cause of damage to red pine ( Pinus resinosa seedlings in nurseries. The fungus can also be latent pathogen seedlings, persisting the absence gross symptoms and later proliferating under conditions that induce host stress. In fall 2004, three nurseries Wisconsin were surveyed determine potential for occurrence shoot blight on jack banksiana persistence D. or asymptomatic this species. Incidence was quantified five 1 m...
Previous reports regarding rhizodeposits from apple roots are limited, and complicated by microbes, which readily colonize root systems contribute to or modify rhizodeposit metabolite composition. This study delineates novel methods for collection of under axenic conditions, indicates genotype-specific differences, validates the contributions vegetative activity quantity. Primary phenolic metabolites collected two rootstock genotypes, G935 M26, were delineated months after initiation...
The transition from cold storage to ambient temperature alters apple quality through accelerated softening, flavor and color changes, development of physiological peel disorders, such as superficial scald, in susceptible cultivars. To reveal global metabolism associated with this transition, the ‘Granny Smith’ metabolome was evaluated during 6 months shelf life periods. Treatment antioxidant diphenylamine (DPA) reduced creating a metabolic contrast untreated fruit, which developed scald....
Damping off of chickpea (Cicer arietinum) can lead to stand loss and yield reduction. Fungicide seed treatments are able successfully control damping off, but the effectiveness many commercially available biological has not been well tested. The objective this study was test effect fungicide on cultivars kabuli desi types. Bacillus pumilus GB34 (Yield Shield), subtilis GB03 (Kodiak), B. MBI 600 (Subtilex), Streptomyces lydicus WYEC 108 (Actinovate), griseoviridis K61 (Mycostop), Trichoderma...
Abstract Quality assessment of pome fruits (i.e. apples and pears) is used not only for determining the optimal harvest time but also progression fruit‐quality attributes during storage. Therefore, it typical to repeatedly evaluate course a postharvest experiment. This evaluation often includes careful visual assessments fruit apparent defects physiological symptoms. A general best practice quality rate using same individual rater or group raters reduce bias. However, such consistency across...
Haskap (Lonicera caerulea L.) is a relatively new berry crop in North America, and little research exists regarding its postharvest storage characteristics or life. Postharvest changes quality, principal factors limiting life at 1.1 °C 95% relative humidity, were evaluated up to 14 days for three cultivars 2019 28 six 2020. Containerized berries periodically assessed soluble solids content (SSC), skin rupture force (SRF) (both 2020) flesh firmness, titratable acidity (TA), Brix/acid ratio...
‘Honeycrisp’ apple is susceptible to the postharvest chilling disorder soft scald that renders fruit unmarketable. Reducing or preventing this an important component of management. In commercial settings, advanced maturity and orchard history contribute estimation susceptibility, but additional at-harvest information indicative risk would enable better management decisions. study, we obtained from orchards for 3 successive years, assessed field growing degree days (GDD), hours (CH), quality...
The physiology and metabolism characterizing postharvest chilling CO 2 injury in apple has important implications for management of soft scald soggy breakdown. This research assessed differences primary related to breakdown (cortex CI) cortex ‘Honeycrisp’ fruit. Results indicate that prestorage temperature conditioning, diphenylamine (DPA), CA treatments alter fruit affect peel storage disorder outcome. A preliminary summary involved with under high includes increased activity...
