Skin color is a key quality attribute of fruits and how to improve fruit coloration has long been a major concern. 5-Aminolevulinic acid (ALA), a natural plant growth regulator, can significantly increase anthocyanin accumulation in fruit skin and therefore effectively improve coloration of many fruits, including apple. However, the molecular mechanism how ALA stimulates anthocyanin accumulatio...

Apples (Malus domestica Borkh.) have been identified as one of the main dietary sources of antioxidants, mainly phenolic compounds. These compounds vary in their composition and concentration, among cultivars and fruit tissues. In this research, the total phenolic content (Folin-Ciocalteau assay), antioxidant capacity (Ferric Reducing Antioxidant Power, FRAP assay) and mineral composition in th...

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...

Fruit development in higher plants normally requires pollination and fertilization to stimulate cell division of specific floral tissues. In some cases, parthenocarpic fruit development proceeds without either pollination or fertilization. Parthenocarpic fruit without seed has higher commercial value than seeded fruit. Several apple (Malus domestica) mutants (Rae Ime, Spencer Seedless and Welli...

Apple pomace is a waste product of the apple manufacturing industry that has been in the focus of life sciences as it represents a low-cost source of fruit-derived compounds. High fruit consumption is associated with beneficial health effects, and therefore, apple pomace and its constituents raise therapeutic interest. The present work reviews (i) the chemical constituents of apple pomace, (ii)...

Diseases in fruit cause devastating problem in economic losses and production in agricultural industry worldwide. In this paper, an adaptive approach for the identification of fruit diseases is proposed and experimentally validated. The image processing based proposed approach is composed of the following main steps; in the first step K-Means clustering technique is used for the defect segmenta...

One of the requirements of a fruit harvesting robot is the ability to recognize and locate fruit from the leaf and branch portions; machine vision system is one of the methods used to detect the location of the fruit. This paper showed the development of a machine vision algorithm that would guide an apple harvesting hand prototype. The objectives of this study were to differentiate the fruit f...

abstract- mechanical damage degrades fruit quality in the chain from production to the consumption. damage is due to static, impact and vibration loads during processes such as harvesting, transportation, sorting and bulk storage. in the present study finite element (fe) models were used to simulate the process of static bruising for apple fruits by contact of the fruit with a hard surface. thr...

cross pollination in some of apples cultivar exists; also iran is near the origin of apple trees so, large genetic diversity can be seen between iranian cultivar. also very famous apple cultivar is known in iran for special flavor and taste. the name of this cultivar is golab. this research was studied in the years 2010 and 2011 in khorasan razavi province on golab apple ecotypes to evaluate ch...

At harvest, apple fruit are placed into wooden or plastic bins (approximately 400 kg of fruit per bin), which are then transported to storage and packing facilities. Prior to storage, fruit may be drenched with a fungicide to control postharvest diseases (10). Fruit are stored in the bins in either regular atmosphere (RA) or controlled atmosphere (CA) (1 to 2% O2 and 0.5% CO2) at –1 to 3°C (9)....
