In other to study the effects of salicylic acid on reproductive characters of ‘Elberta’ Peach (Prunus persica L. Batsch) tree, an experiment was carried out based on randomized complete blocks design with four replications in commercial orchard, Kerman, Iran. The application of three concentrations of salicylic acid 0 (control), 1and 2 mM at swollen bud stage were used. Results showed that appl...

A general method has been developed for determination of the total cyanide content of all cyanogenic plants and foods. Ten cyanogenic substrates (cassava, flax seed, sorghum and giant taro leaves, stones of peach, plum, nectarine and apricot, apple seeds and bamboo shoot) were chosen, as well as various model compounds, and the total cyanide contents determined by the acid hydrolysis and picrat...

peach (prunus persica l. batsch.) is produced in most areas of iran, where flowering is hindered by temperature. using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. the objective of this study was to determine the effects of methyl jasmonate (mj) and salicylic acid (sa) on peach bloom delay and yield.  this study evaluated the applications of mj 0 (contro...

Peach (Prunus persica, Rosaceae) is an extremely popular tree fruit worldwide, with an annual production near 20 million tons. Peach is widely thought to have origins in China, but its evolutionary history is largely unknown. The oldest evidence for the peach has been Chinese archaeological records dating to 8000-7000 BP. Here, we report eight fossil peach endocarps from late Pliocene strata of...

in this research, population fluctuation of canola aphids and their natural enemies were investigated during 2007-2008. random samples of 50 plants were taken twice a week. mustard aphid (lipaphis erysimi kalt.), green peach aphid(myzus persicae sulzer)and cabbage aphid (brevicoryne brassicae l.) were recorded on canola. however,the mustard aphid with relative frequency of 79% was dominant. the...

During the 1995 season, large (-275g), medium (175g) and small (125g) ’O’Henry’ peaches were stored in either air, 5% CO, + 2% 0, or 17% CO, + 6% 0, at 38°F (3.3”C). Large ‘O’Henry’ peaches benefited more from the 17% CO, + 6% 0, than from either the 5% CO, + 2% 0, or the air storage treatment. During the 1996 season, large, medium and small ‘Elegant Lady’ and ’O’Henry’ peaches were stored in a...

Introduction Peach allergy is one of the most common allergies in subjects with reactions to plant-foods. The relationship between peach allergy and other foods and the sensitization pattern in these patients have not been studied in detail. We study the sensitization to relevant allergens, such as peach and peanut LTP, Prup3 and Arah9, and seed storage protein, Arah2. Studies were carried out ...

Rosaceae fruit allergy is the most common food allergy in Europe in patients over 5 years of age. The two fruits most frequently involved are peach and apple. Different clinical phenotypes of peach allergy are observed across Europe in relation to different allergen sensitisation patterns to the peach allergens Pru p1 (Bet v 1 homologue), Pru p 3 (peach lipid transfer protein, LTP), and Pru p 4...

Peach latent mosaic viroid (PLMVd) is a member of the genus Pelamoviroid in the family Avsunviroidae and infects peach trees. We de novo assembled a PLMVd genome from a peach transcriptome and identified 18 variants in a single peach cultivar, after sequencing 20 PLMVd genomes by Sanger sequencing.
