The anatomy of Prunus dulcis was analyzed by applying several differential staining techniques and light microscopy. Prunus dulcis seed has a thin and structurally complex seed coat, with lignified cellulosic tissue. The embryo has two voluminous cotyledons. Cotyledon cells have a high number of protein and lipid bodies, some of which have phytin. The provascular tissue, located in the cotyledo...

almond (prunus dulcis [webb] d.a. mill) is an economically important species of genus prunus (rosaceae, subfamily prunoideae). the commercial edible part of almond fruit is kernel. fertilization is essential for nut production in almond but most cultivars are self or even cross-incompatible. self-incompatibility in almond is gametophytic and controlled by a single s-locus with multiple codomina...

The majority of commercial almonds grown in California undergo pasteurization using a validated process such as moist heat exposure (MH) or fumigation with propylene oxide (PO) to reduce the potential Salmonella bacteria contamination. Although these treatments are common, their effect on raw almond storage quality is not well understood. To address this, were either pasteurized MH and PO left ...

Almond nuts were exposed to radiation doses of 1, 2 and 3 kGy of gamma irradiation covering the range for insect/pest disinfestations and for microbial load. Fatty acid composition, acidity value, peroxide value, iodine value specification number, TBA value and color of almond oil extracted from un-irradiated and irradiated sample were determined, immediately after irradiation and after 12 mont...

to determine the specificity and host range of wilsonomyces carpophilus isolates, some stone fruit seedlings (prunus armeniaca, prunus dulcis, prunus reuteri, p. vulgaris, p. domestica, p. persica, p. avium and p. cerasus), pome fruits (malus communis, pyrus communis, crataegus azarollus and crataegus monogyna) as well as ornamental plants (rosa persica, rosa sp. and r. damascena) were selected...

this study was undertaken to identify morphological changes in young seedlings of 5 iranian almond species (prunus dulcis, p. eburnea, p. eleagnifolia, p. haussknechti, and p. scoparia) under polyethylene glycol-induced drought stress. drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs, leaf number, total leaf area, and leaf re...

Almond cultivation in the Mediterranean area has undergone important changes leading to current trend of intensification. In this scenario, low-vigor rootstocks have recently been developed, such as ‘Rootpac®’ series, but knowledge about rootstock’s influence on adaptation high-density planting systems is very scarce. The objective work was assess morphological and physiological response four a...

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)...
