Sweet cherry (Prunus avium L.) is one of the most important stone fruit species in Bulgaria. The known to be susceptible more than 30 viruses. Among them are prune dwarf virus (PDV), prunus necrotic ringspot (PNRSV) and apple mosaic (ApMV), ilarviruses. Testing for these viruses required certification schemes order provide virus-tested propagated material fruit-growing industry prevent their di...

BACKGROUND The use of traps and other attract-and-kill devices in pest management strategies to reduce Mediterranean fruit fly populations has proved to be efficient. Nevertheless, many farmers are concerned about the effect of these devices on the trees where they are hung. Direct field observations have revealed that fruit damage is higher in trees with traps than in trees without them. This ...

This study was carried out on olive trees cv. Amygdalifolia, to investigate the effect of spraying potassium nitrate, KnO3, and zinc sulfate, ZnSo4, on the fruit weight, dimension and volume. The plants were sprayed with 0, 0.5, 1.0 and 1.5% KnO3 and 0, 0.25, 0.50 and 0.75% ZnSO4 and their combinations in August about halfway through the fruit growth period. The highest fruit weight was observe...

The present article is devoted to the study of foreign cherry varieties on different rootstocks. Of all stone fruit crops, most common cherry. Cherry fruits are particularly valuable products, which have not only nutritional but also medicinal properties. diversity varieties, determined by their morphological features, used as a means production in certain natural and economic conditions. In th...

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

this study was carried out on olive trees cv. amygdalifolia, to investigate the effect of spraying potassium nitrate, kno3, and zinc sulfate, znso4, on the fruit weight, dimension and volume. the plants were sprayed with 0, 0.5, 1.0 and 1.5% kno3 and 0, 0.25, 0.50 and 0.75% znso4 and their combinations in august about halfway through the fruit growth period. the highest fruit weight was observe...

The development of flower buds and a sufficient fruit set are basic requirements for fruit growers to generate a marketable crop. However, fruit trees remain in a juvenile (nonflowering) phase for years, and after a transition period of getting reproductively competent they enter the adult phase of tree life. The reproductive phase is associated with the ability to alternate between the product...

Ecological complexity has been proposed to play a crucial role in primate brain-size evolution. However, detailed quantification of ecological complexity is still limited. Here we assess the spatio-temporal distribution of tropical fruits and young leaves, two primary chimpanzee (Pan troglodytes) foods, focusing on the predictability of their availability in individual trees. Using up to 20 yea...

This study was conducted in stone fruit orchards five provinces of the East Mediterranean Region Turkey between years 2009-2011. The aim to determine potential aphid vectors quarantine pathogen PPV (plum pox virus, family Potyviridae) that causes serious yield losses. During surveys, 542 orchard/nurseries were sampled and 6 species (Hemiptera: Aphididae) [Brachycaudus persicae (Passerini,1860),...
