Mahaleb (Prunus mahaleb L.) is an important rootstock for P. avium and P. cerasus cultivars. The present study has compared the phenolic contents and antioxidant activity of the methanolic extracts of the barks, leaves and fruits of ten selected mahaleb genotypes. The total phenolic content (5.11-131.77 mg GA g-1) in barks and the total flavonoid (54.06-180.6 mg QE g-1) and proanthocyanidin (8....

this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...

clementine mandarin (citrus clementina) is one of the suitable/marketable citrus species in north of iran; however, as a disadvantage has small fruits. in order to produce new citrus cultivar with large and good quality fruit, a project with four phases was conducted from 1989 until 2009. the first phase was started with controlled cross pollination between clementine mandarin as maternal, and ...

The genetic and environmental variation for flesh color of tomato (Lycopersicon esculentum Mill.) fruit was quantified using 41 red-fruited breeding lines, open-pollinated cultivars, and hybrids that are representative of the diversity of tomatoes grown for whole-peel processing in the midwestern and eastern United States and Ontario, Canada. Objective color measurements were made for 2 years f...

Enzymes interact to generate metabolic networks. The activities of more than 22 enzymes from central metabolism were profiled during the development of fruit of the modern tomato cultivar Solanum lycopersicum 'M82' and its wild relative Solanum pennellii (LA0716). In S. pennellii, the mature fruit remains green and contains lower sugar and higher organic acid levels. These genotypes are the par...

A typical symptom of postharvest chilling injury (PCI) in pineapple fruit (Ananas comosus (L.) Merr.) is internal browning (IB) near the fruit core. Since vascular bundles (VBs) are localized to this region, it was hypothesized that the VBs might be the site of IB. To test this, the anatomy and histochemistry of VBs during chilling stress in four pineapple cultivars with different levels of sen...

Surinam cherry is a native fruit tree with market potential. However, the pulp yield can be impaired by size of seed. At UTFPR there genotype which produces seedless fruits, that intensify use this species in orchards, and it important to analyze quality produced fruit. The aim study was determine fruits from pirenic apirenic accessions (Eugenia uniflora). In 2012, 2013 2015, 40 ripe were colle...

The Chinese cherry (Prunus pseudocerasus/Cerasus pseudocerasus), which is native to China, an economically important tetraploid fruiting species. Its industry has been greatly limited due some general disadvantages in the fruits such as small fruit size, high acid content, and short shelf-life. As such, it urgent carry out cross breeding genetic improvement of this Here, seven combinations were...

Tree fruit breeding is an inherently long-term process. The average generation time can range from 2 to 20 years depending on the species. While the production of large numbers of progeny favors the appearance of rare but desired recombinants, large tree size limits the number of progeny that can be planted and maintained. Significant genotype x environment interactions require multiple test si...

Non-travel-related hepatitis A is rare in Canada. We describe a hepatitis A outbreak investigation in British Columbia in February to May 2012 in which exposure history was collected from nine confirmed non-travel-related cases. Suspected foods were tested for hepatitis A virus (HAV): a frozen fruit blend was identified as a common exposure for six of the nine cases using supermarket loyalty ca...
