Nitrate reductase was found in leaves of apricot Prunus armeniaca, sour cherry P. cerasus, sweet cherry P. avium, and plum P. domestica, but not in peach P. persica, from trees grown in sand culture receiving a nitrate containing nutrient solution. Nitrate was found in the leaves of all species. Nitrate and nitrate reductase were found in leaves of field-grown apricot, sour cherry, and plum tre...

In a trial to determine if flowering cherries (Prunus serrulata Lindl.) were a source of little cherry disease, infection was found in seven of 10 species and cultivars tested. In an orchard trial with the cultivar 'Lambert', fruit symptoms of little cherry occurred in infected trees in the fifth year of fruiting, 8 years after planting. The symptoms also occurred in the two succeeding years, a...

Pollen competition and selection have significant evolutionary consequences, but very little is known about how they can be modulated. We have examined in cherry (Prunus avium L.) how pollen performance is affected by the genotype of the pollen and by the environmental conditions under which it grows, namely the pistilar tissue and temperature. The different pollen donor genotypes tested in thi...

bacterial canker of stone fruit trees caused by pseudomonas syringae pv. syringae has become widespread throughout most fruit growing areas of iran (abbasi et al 2013). to evaluate the diversity of the strains and possible species inciting the disease in the central areas of the country, surveys were made in 2014 and 2015 in some central provinces including charmahal-and-bakhtiary, isfahan, qum...

The effects of preharvest calcium chloride (CaCl2) treatment on some quality characteristics and bioactive compounds sweet cherry fruit (Prunus avium L. cvs. 0900 Ziraat, Sweetheart Merton Late) were investigated. CaCl2 (1%) solution was sprayed to the trees at 21 35 days after full bloom stage. served as control treated with distilled water same days. remarkably suppressed respiration rate inc...

Sweet cherry (Prunus avium L.) fruits are characterised by a short shelf life. To extend the life, pre-storage hydrocooling is carried out to reduce their temperature before storing them in cold storage. During 2015 and 2016, treatment on of two sweet cultivars, 'Kordia' 'Regina', from orchards locality Trebinje, was performed. Samples both cultivars were subjected an automatic system at 0.9 ºC...

The skin of developing soft and fleshy fruit is subjected to considerable growth stress, and failure of the skin is associated with impaired barrier properties in water transport and pathogen defence. The objectives were to establish a standardized, biaxial tensile test of the skin of soft and fleshy fruit and to use it to characterize and quantify mechanical properties of the sweet cherry (Pru...

In this article, we reported the original data obtained by the study of metabolites and enzymes involved in sweet cherry antioxidant system. We measured hydrogen peroxide (H2O2) and malondialdehyde (MDA), which are indicator of oxidative stress. Moreover, we measured the concentration of reduced and oxidized ascorbate and glutathione that are involved in ROS detoxification together with phenoli...

Treeshelters are widely used to protect tree seedlings against animal browsing or rubbing. They reduce the tree transpiration as a result of the low ventilation rate of the shelter. Photosynthesis is impeded by low levels of available CO2 due to poor gas exchange with the outside. We assess the impact of ventilating a treeshelter on the microclimate, on the transpiration and on the photosynthes...

Studies of the signal transduction mechanisms underlying learning and memory have provided many new insights into the molecular mechanisms underlying associative conditioning in mammals. In this issue of Neuron, Gean and colleagues report the discovery that the PI-3 kinase/AKT(PKB) pathway contributes to LTP and the consolidation of amygdala-dependent cued fear conditioning in rats.
