Unraveling Molecular Mechanisms Regulating Dormancy and Bloom Time in Apple (Malus × domestica Borkh)
Bud dormancy is an essential characteristic of deciduous woody perennials, including apple, to cope with the low temperatures during winter. The release from dormancy and subsequent budburst in apple can only occur after fulfillment of chilling and heat requirements. In the Mid-Atlantic region, …

Systems-Level Analysis of Rootstock–Scion Interactions in Apple Reveals Mechanisms of Cold Tolerance Under Field Frost Events
Late spring frosts threaten apple (Malus × domestica Borkh.) productivity by damaging developing floral buds, yet the mechanisms underlying rootstock-dependent cold tolerance in orchard conditions remain poorly understood. In this study, we investigated frost tolerance in two apple (Malus domestica …

Gas exchange characteristics of apple and peach leaves as influenced by European red mite and twospotted spider mite
… greenhouse-grown 'Imperial Delicious' apple (<i>Malus domestica</i>) and 'Redhaven' peach (<i>Prunus persica</i>) leaves. As ERM- and TSM-days increased, apple leaf net photosynthesis (Pn), transpiration (Tr) , and chlorophyll content (TCHL) decreased linearly. TSM was more damaging to apple leaf …

Impact of Phytosanitary Irradiation on Polar Antioxidants in Peels of ‘Granny Smith’ Apples
<p>The ‘Granny Smith’ apple (<em>Malus domestica Borkh</em>), known for its bright green peel and tart flavor, is a significant cultivar in the United States. Due to increasing limitations and restrictions on chemical fumigants and other treatments, ionizing radiation is gaining popularity as a …

Aronia mitschurinii: Solving a Horticultural Enigma
… maternal diploid <em>A. melanocarpa </em>and <em>Malus domestica</em>, <em>Photinia serrulata</em>, <em>Sorbus</em>, and ×<em>Sorbaronia</em>. Clustering of AFLP similarity data using the unweighted pair group method with arithmetic mean (UPGMA) identified <em>A. mitschurinii </em>as distinct from …

Plant virus detection and diversity in a mixed tree fruit orchard determined through metagenomic-based analysis of honeybee (Apis mellifera) collected samples
… avium), peaches (Prunus persica), and apples (Malus domestica). Genomics-based sequencing on bees and bee-related plant material collected during peak bloom periods for each plant species revealed 21 viral species. Cherry virus A (CVA), prune dwarf virus (PDV), and prunus necrotic ringspot …

Microbial Ecology and Horticultural Sustainability of Organically and Conventionally Managed Apples
… and conventionally managed apple trees (Malus domestica Borkh) were evaluated for three growing seasons (2005-2007) to examine the impact of organic and conventional pesticide applications on the microbial ecology of phyllosphere and soil microflora. An important objective was to …

Skin Deep: Genetic Characterization And Prediction Of Russet Formation In ‘Honeycrisp’-Derived Apple Breeding Germplasm
Russet formation in apples (Malus domestica Borkh.) is a superficial skin disorder that detracts from fruit appearance and is a breeding target in many apple scion breeding programs. To-date, the understanding of the genetic basis of russet in apple has been limited to a relatively narrow set of …

The Effects of Rootstock Selection and Carbon-based Fertility Amendments on Apple Orchard Productivity and Soil Community Ecology
In apple (Malus domestica Borkh.) orchards, rootstock genotype, and soil fertility management practices impact soil fertility, plant associated soil microbial communities, and orchard productivity. Apple growers select rootstocks to confer beneficial traits, including size control, precocity, and …

Physiological studies of bitter pit in apple
… physiology of the disorder bitter pit in apple (Malus domestica Borkh.) were studied. A two year field study was conducted to induce consistent bitter pit development in type ’Delicious’ (D) and ’Golden Delicious’ (GD) apple fruit. Multiple spray treatments of CaCl₂ and MgCl₂, combined with paper …

Evaluation of rootstock and crop load effects on the performance of `Gibson Golden Delicious' and three scab-resistant apple cultivars
… an established `Gibson Golden Delicious' apple (Malus ×domestica Borkh.) orchard to evaluate the effects of dwarfing rootstocks under different crop load levels on tree growth, yield, fruit quality, and return bloom. Treatments included five dwarfing rootstocks and trees that were hand thinned to …

Identifying and characterizing genes and transcription factors involved in coloration of apple fruit
Apple (Malus × domestica Borkh.) is one of the most highly cultivated fruit crops grown around the world and apple consumption has been increasing over the years. One of the most important determinants of fruit quality is skin color. Red coloration in apple fruit is attributed to anthocyanin …

Characterisation of Flavonoid Composition and Glycosylating Enzymes in Sweet Cherry and Apple Fruit
… flavonoid biosynthesis pathway of both apple (Malus domestica L.) and sweet cherry was investigated through the identification of UFGT genes and characterisation of the associated proteins. The glycosylation step is of significant interest due to the capacity of this modification to improve the …

Interaction Between Insects and Apple (Malus X Domestica Borkh.): Insect Behavior, Genotypic Preference, and Plant Phenolics With Emphasis on Japanese Beetle (Popillia Japonica Newman)
Leaves and fruit of nine apple (Malus x domestica Borkh.) genotypes were evaluated for insect injury in 1998 and 1999. Foliar and fruit injury from 12 insect species was inconsistently affected by genotype. Spraying trees with oil affected neither fruit insect injury nor fruit phytotoxicity. In …
