Diabetes mellitus was induced in 32 out of 40 adult male albino rats using intravenous injection of 50 mg/kg BW of alloxan. Then, the diabetic rats were divided into four groups, three of which fed a diet containing 8 % BW ethanol (polar solvent), cyclohexane (nonpolar solvent) and ether (intermediate solvent) extracts of walnut leaf for 21 days. The fourth (positive control) group received a n...

introduction: walnut leaf contains large amounts of antioxidants, phenolic compounds and flavonoids and the beneficial effect of these compounds in the treatment of diabetes has been shown. this study investigated the effect of cyclohexane and ethanol extract of walnut leaf on activity of sorbitol dehydrogenase (sdh) enzyme. methods: fifty- six adult male sprague-dawley rats were divided into s...

to study allelopathic effects of iranian walnut (juglans regia l.) on germination and initial growth of purslane (portulaca oleracea) and redroot pigweed (amaranthus retroflexus) an experiment was conducted in shahed university. the result showed that fresh leaf had negatively effected on radicle length. also, with increasing extract concentrations of persian walnut, the seed germination and se...

vegetative propagation of persian walnut encounters a major problem in iran growing conditions. this experiment was carried out to study the physiological effects of rootstock as regards herbaceousness or woodiness, and with respect to the presence of leaf on it or not on minigrafting success. throughout the study, 1.5-2.5 cm length persian walnut scions were minigrafted on herbaceous vs. softw...

This was the second year of a study which evaluated the genetic variation among English walnut germplasm in response to infection by Xanthomonas campestris pv. juqlandis (Xcj), the bacterium which causes the disease walnut blight. Immature leaves and nuts of 10 walnut accessions representing the breadth of currently available germplasm were inoculated. Leaves were scored for disease severity at...

Temporal and spatial variations in the water status of walnut trees (Juglans regia L.) and the soil in which they were growing were traced by analyzing the differences in hydrogen isotopes during spring and summer in a 7-year-old walnut stand. Walnut root dynamics were measured in both dry and wet seasons. Walnut roots were mainly distributed in the upper soil (0-30 cm depth), with around 60% o...

The rainfastness of a microencapsulated sex pheromone formulation for codling moth, Cydia pomonella (L.), was evaluated in a series of laboratory experiments with detached apple, pear, and walnut leaves. Increasing the intensity and duration of simulated rainfall significantly increased the removal of microcapsules from both the top and bottom of apple leaves. The removal of microcapsules was s...

Walnut is an important crop that widely grown for its edible nuts, timber, and other commercial uses. pests can cause significant damage to the trees reduce quality quantity of crop. blister beetles walnut trees, especially during early stages fruit development. The data generated on incidence severity revealed E. erinea commenced from 13th standard meteorological week (SMW) with mean 1.2 per l...
