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...

Allelopathic effects of juglone and walnut leaf extracts from Persian walnut (Juglans regia L.) on yield, growth, chemical and plant nutrient element composition of the day-neutral strawberry (Fragaria × ananassa L.) cultivar Fern were investigated as part of an effort to identify tolerant species to plant adjacent to walnut. Strawberry plants were treated with juglone (5-hydroxy-1.4 naphthoqui...

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...

there is some report about the hypoglycemic effect of juglans rejia l. leaf in alloxan induced diabetic rats and hypoglycemic effect of its fruit peel administered intra peritoneally. thirty male wistar rats divided into five groups, to evaluate the hypoglycemic and pancreas β-cells regenerative effects of oral methanolic extracts of leaf and fruit peel of walnut. rats were made diabetic by int...

Molecular and physiological studies in walnut (Juglans regia) are combined to establish the putative role of leaf plasma membrane aquaporins in the response of leaf hydraulic conductance (K(leaf)) to irradiance. The effects of light and temperature on K(leaf) are described. Under dark conditions, K(leaf) was low, but increased by 400% upon exposure to light. In contrast to dark conditions, K(le...

Black walnut, a valuable economic and environmentally important species, is threatened by thousand cankers disease. Systemic imidacloprid and dinotefuran applications were made to mature black walnut trees to evaluate their translocation and concentration levels in various tissue types including leaf, twig, trunk core, nutmeat, and walnut husk. The metabolism of imidacloprid in plants produces ...

Fruit color is an important economic trait. The color of red walnut cultivars is mainly attributed to anthocyanins. The aim of this study was to explore the differences in the molecular mechanism of leaf and peel color change between red and green walnut. A reference transcriptome of walnut was sequenced and annotated to identify genes related to fruit color at the ripening stage. More than 290...
