Fresh peaches are highly perishable and they deteriorate quickly during low temperature storage which results in losses in nutritional quality. To prevent these adverse effects, peach fruits were treated by dipping with γ-aminobutyric acid (GABA; 2, 4 and 6 mM) immediately after harvest and then stored at 1 °C for 7, 14, 21, and 28 days. Peach fruits treated with GABA exhibited higher flesh fir...

Objective A group of 148 peach allergic patients, recruited in a ongoing clinical study (Clinical Trials.gov, protocol ID NCT00715156) aimed at studying the relationship between the clinical manifestations to peach and the positivity to different peach major allergens (Pru p 3, 1 and 4), were divided into 2 groups according to peach induced symptoms: group A (mild-OAS; 76 pts) and group B (seve...

Methods We included 60 subjects in different groups: Group 1, peanut and peach allergy; Group 2, peanut allergy and good tolerance to peach; Group 3, peach allergy and good tolerance to peanut; Group 4, good tolerance to peach and peanut. The diagnostic was performed by clinical history, skin prick test and/or double blind placebo controlled food challenge. BAT to Arah1, Arah2, Arah3, Arah6, rA...

in order to evaluate tolerance of four prunus rootstocks to fe-deficiency-induced chlorosis,  an experiment was carried out in bu-ali sina university in 2012 using a rcbd design with four replications. four rootstocks were used, including gf677, gn15, bitter almond and peach and nutritional treatments were: hoagland solution without fe (ph = 6), hoagland solution containing 90µm fe as control (...

High concentrations of indole-3-acetic acid (IAA) are required for climacteric ethylene biosynthesis to cause fruit softening in melting flesh peaches at the late ripening stage. By contrast, the fruits of stony hard peach cultivars do not soften and produce little ethylene due to the low IAA concentrations. To investigate the regulation of IAA accumulation during peach ripening [the transition...

The glassy-winged sharpshooter, Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae), is an important insect vector of the xylem-limited plant pathogen Xylella fastidiosa Wells et al. that causes diseases in numerous plant species including food and feedstock crops, ornamentals and weeds. Both the pathogen and the vector are native to the Americas, and H. vitripennis has demonstrated high...

Inorganic copper is used as a broad-spectrum fungicide and bacteriocide on a variety of agricultural crops. After application, the copper residue typically accumulates in the upper 15 cm of soil. Data from the California Pesticide Use Reports were used to estimate the augmentation of copper in the soil that resulted from pesticide applications for the six years from 1993 to 1998 on 12 crops tha...

this study was performed to investigate the effect of putrescine and spermine on some physiological and biochemical characteristics and antioxidant enzymes activity of peach (prunus persica cv. alberta) and almond (prunus dulcis cv. rabi) seedlings under water deficit. the first factor was water regime at two levels (80% or 50% of soil available water), and the second factor was polyamine treat...
