The two acknowledged vectors of ‘Candidatus Phytoplasma mali’ in north-western Italy, the psyllid Cacopsylla melanoneura and the leafhopper Fieberiella florii, have been compared to highlight their role in the apple proliferation epidemiology in relation to their infectivity, transmission efficiency and permanence in apple orchards and in wild vegetation, predominantly hawthorn formations. The ...
This work presents an algorithm for estimating the number of apples on trees using images acquired with a standard color CCD camera. The proposed system is capable of correctly identifying and localizing more than 85% of the apples in the images. To achieve this high detection rate, color and texture analyses are combined together with shape analysis. In the first step, pixels with a high proba...
miRNAs are important regulators involving in plant-pathogen interactions. However, their roles in apple tree response to Valsa canker pathogen (Valsa mali, Vm) infection were poorly understood. In this study, we constructed two miRNA libraries using the twig bark tissues of apple tree (Malus domestica Borkh. cv. "Fuji") inoculated with Vm (IVm) and PDA medium (control, BMd). Among all detected ...
T recent discovery of light brown apple moth, a leafroller, in California may affect the management of fruit crops, and because it is a quarantine pest in some markets, the discovery has already had implications for domestic and export trade in produce and nursery stock. In New Zealand, light brown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), was first reported in 1891 ...
ABSTRACT Epidemiological studies show that consumption of fruits and vegetables is associated with beneficial effects on human health including reduced risk of coronary artery disease (CAD). Fruits and their juices contain phytochemicals that inhibit in vitro low-density lipoprotein (LDL) oxidation and may account, in part, for their protective effect. However, reports of in vivo antioxidant ef...
Shape is not only an important indicator for assessing the grade of the apple, but also the important factors for increasing the value of the apple. In order to improve the apple shape classification accuracy rate, an approach for apple shape sorting based on wavelet moments was proposed, the image was first subjected to a normalization process using its regular moments to obtain scale and tran...
Molecular genetic markers complement archaeological, breeding and geographical investigations of the origins, history and domestication of plants. With increasing access to wild apples from Central Asia, along with the use of molecular genetic markers capable of distinguishing between species, and explicit methods of phylogeny reconstruction, it is now possible to test hypotheses about the orig...
Organic apple cider vinegar is produced from apples that go through very restricted treatment in orchard. During the first stage of the process, the sugars from apples are fermented by yeasts to cider. The produced ethanol is used as a substrate by acetic acid bacteria in a second separated bioprocess. In both, the organic and conventional apple cider vinegars the ethanol oxidation to acetic ac...
BACKGROUND To monitor the richness in microbial inhabitants in the phyllosphere of apple trees cultivated under various cultural and environmental conditions, we developed an oligo-DNA macroarray for major pathogenic and non-pathogenic fungi and bacteria inhabiting the phyllosphere of apple trees. METHODS AND FINDINGS First, we isolated culturable fungi and bacteria from apple orchards by an ...
Deciphering the genetic control of flowering and ripening periods in apple is essential for breeding cultivars adapted to their growing environments. We implemented a large Genome-Wide Association Study (GWAS) at the European level using an association panel of 1,168 different apple genotypes distributed over six locations and phenotyped for these phenological traits. The panel was genotyped at...
