The phenolic composition of skin and flesh from Malus domestica apples (Anna cultivar) and Prunus domestica plums (satsuma cultivar) commercial cultivars in Costa Rica, was studied using Ultra Performance Liquid Chromatography coupled with High Resolution Mass Spectrometry (UPLC-DAD-ESI-MS) on enriched-phenolic extracts, with particular emphasis in proanthocyanidin and flavonoids characterizati...

This study examined the effect of debagging time on color and flavor / taste compounds in the non-red apple cultivar 'Golden Delicious' and red cultivar 'Qinguan' at mid and late stages of fruit development. Debagging briefly improved the red color in both cultivars, the peel of 'Golden Delicious' presenting pale-pink hue. However, rapid anthocyanin accumulation occurred in apple peel at a spec...

Red coloration of apple (Malus x domestica) skin is an important determinant of consumer preference and marketability. Anthocyanins are responsible for this coloration, and their accumulation is positively correlated with the expression level of anthocyanin biosynthetic genes. Regulation of expression of these genes is believed to be controlled by MYB transcription factors, and the MYB transcri...

Current consumer trends require food products with „healthy image“. This has led to an increased interest in traditional fruit cultivars and related products. Traditional apple cultivars in Bosnia and Herzegovina are a valuable source of desirable genetic characteristics including important pomological, nutritional and technological characteristics of the fruit. The sugar and organic acid profi...

The number of local and traditional fruit cultivars in Andalusia (Southern Spain) has decreased dramatically since the 1970s when new commercial cultivars from breeding programs were introduced, replacing old varieties, and thus decreasing genetic diversity. The present study was included in a genetic resources project with the objective of identifying and preserving traditional fruit tree cult...

This paper summarizes the information on the occurrence of phenolic compounds in apple (Malus x domestica Borkh.) fruit and juice, with special reference to their health related properties. As phytochemical molecules belonging to polyphenols are numerous, we will focus on the main apples phenolic compounds with special reference to changes induced by apple cultivar, breeding approaches, fruit p...

Proanthocyanidins (PAs) are products of the flavonoid pathway, which also leads to the production of anthocyanins and flavonols. Many flavonoids have antioxidant properties and may have beneficial effects for human health. PAs are found in the seeds and fruits of many plants. In apple fruit (Malus × domestica Borkh.), the flavonoid biosynthetic pathway is most active in the skin, with the flava...

Orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. Intensification is possible using dwarfing rootstocks that control tree size, induce early cropping and produce large quantities of fruit compared to the amount of wood produced. Therefore, this study attempts to compare some yield and fruit properties of ...

Nano-fertilizers can increase value of products in agriculture. Iron plays many important and essential roles in plant growth and development as compared to other micronutrients. In the present study, effects of different levels of enriched nano chelated Iron fertilizer (25, 50, 100, and 200 mg l-1)  were investigated in comparison with the common Iron (FeSO4.7H2O) on in vitro proliferation of ...

Both the origin of domesticated apple and the overall phylogeny of the genus Malus are still not completely resolved. Having this as a target, we built a 134,553-position-long alignment including two previously published chloroplast DNAs (cpDNAs) and 45 de novo sequenced, fully colinear chloroplast genomes from cultivated apple varieties and wild apple species. The data produced are free from c...
