The main characteristics of Narrow Orchard Systems (NOS) are (i) narrow canopies, with (ii) multiple closely-spaced upright leaders and (iii) narrow inter-rows, regardless of tree spacing within the row. In NOS, planting density can be reduced compared with super-high and ultra-high density planting systems on dwarfing rootstocks, utilising a wider range of rootstock vigours coupled to proportional increases in both within-row tree spacing and upright leader number per tree. This paper reviews the development of NOS and results of research carried out on apple, pear, sweet cherry, peach, nectarine, apricot and plum in production regions worldwide. The history of orchard …
Changes In Soil Chemical Attributes, Horticultural Performance And Fruit Yield Of Peach Cultivars Following Preplant And Annual Applications Of Composted Mulch Amendments, Jeffrey Hopkins
All Theses
Southeastern peach orchards often have poor soil quality due to native soil composition, intensive farming practices and generational replanting of trees in the same locations. This study investigated using mulch amendments to improve the chemical and physical quality of soil prior to planting a new peach orchard. At the beginning of the four-year study, a single-ground municipal composted mulch was incorporated into the soil at two different rates and three cultivars of peaches, ‘Rubyprince’, ‘Julyprince’, and ‘BigRed’ were planted on berms. Thereafter, the same mulch product was annually applied to the top of the berms at two different rates to …
Identification And Characterization Of Geotrichum Candidum Isolates From Peach With Reduced Sensitivity To Propiconazole, Sara Price
All Theses
Geotrichum candidum Link (1809) is a yeast-like fungus that causes sour rot of stone fruits, including peach (Prunus persica). The disease caused damage between 2021 and 2023 to the peach crop kept in cold storage at a commercial farm in South Carolina despite preharvest and postharvest applications of fungicides. Isolates from 41 symptomatic fruit, from a South Carolina (SC) commercial packing house, as well as other isolates obtained from South Carolina were identified to be G. candidum based on species-specific PCR amplifications of the β tubulin gene. Commonly used postharvest fungicide fludioxonil had no effect on G. candidum mycelial growth …
Effects Of Thermal Processing On Peach Puree Of Different Cultivars: Analysis Of Biochemical Alteration, Non-Enzymatic Browning Reaction, And Color Changes, James Hayes
All Theses
The effects of pasteurization temperature and time on the change in seven peach puree variables over a 6-week accelerated shelf-life test (35°C) were evaluated. The variables of interest were three color measures [ L* (lightness), a* (redness), and b* (yellowness)]; two brown pigment measures [spectrophotometric absorption at 420 nm (Browning Index) and 443 nm (Hydroxymethylfurfural)]; °Brix; and pH). Puree was collected from three different cultivars (2 freestone and 1 clingstone) and puree samples from each cultivar were subjected to 20 combinations of pasteurization temperatures (70°C, 80°C, 90 °C, 100°C) and same hold times (0 minutes, 1 minute, 3 minutes, 5 …
Fruit Tree Responses To Water Stress: Automated Physiological Measurements And Rootstock Responses, William D. Wheeler
Fruit Tree Responses To Water Stress: Automated Physiological Measurements And Rootstock Responses, William D. Wheeler
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
New orchard plantings utilize trees grafted to dwarfing rootstocks planted close together to facilitate larger harvests. These dwarfing rootstocks have not been comprehensively studied for their ability to withstand drought. This is of special importance in the Intermountain West which has limited rainfall. Additionally, orchard growers face competition for water from a growing population and increased uncertainty in rainfall from climate change. My research examined the use of dendrometers, which measure changes in trunk diameter, and sap flow sensors, which measure how quickly sap moves, as methods to inform growers about tree water status. I also used a weighing lysimeter …
Phenotypic And Genotypic Studies In The Peach [Prunus Persica (L.) Batsch] And Muscadine Grape (Vitis Rotundifolia Michx.), Jennifer Anne Lewter
Phenotypic And Genotypic Studies In The Peach [Prunus Persica (L.) Batsch] And Muscadine Grape (Vitis Rotundifolia Michx.), Jennifer Anne Lewter
Graduate Theses and Dissertations
Peach: Peaches [Prunus persica (L.) Batsch] are routinely chilled to increase shelf-life. Exposure to temperatures of 5° C for two weeks can induce chilling injury (CI) symptoms, including flesh mealiness (or wooliness) and a lack of juiciness. Phenotypic data were collected on seven biparental F1 peach populations maintained at the University of Arkansas Fruit Research Station. A genome wide association study (GWAS) was performed using TASSEL 5 which identified four quantitative trait loci (QTLs) associated with expressible juice, four QTLs for mealiness, five QTLs for soluble solids, and three QTLs for fruit weight. Exploiting these genetic markers could help breeders …
Evaluation Of Fresh-Market Potential Of Arkansas-Grown Fruit: Blackberries, Peaches, Table Grapes, And Muscadine Grapes, Molly Felts
Graduate Theses and Dissertations
Fresh-market produce is a major component of commercial market sales. However, shelf-life of fresh-market produce is limited, so evaluating postharvest potential (time from harvest to consumption) is critical. Fresh-market fruit can be impacted by many factors that deteriorate the quality of the fruit. Understanding the postharvest physiology of fruit can lead to better handling and storage conditions for extended shelf life and enhanced quality for the consumer. This research project was a collaborative effort within the University of Arkansas System Division of Agriculture between the Food Science and Horticulture Departments to evaluate the fresh-market potential of Arkansas-grown fruit. Physiochemical and …
