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...

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...

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...

This study was done to investigate the interaction effect of the mixture of each pair of traditional medicinal plants including: Sage (Salvia officinalis), Hawthorn (Crataegusoxyacantha), Walnut Leaf (Juglansregia L.), Red Cabbage (Brassica oleracea), and Yellow Sweet Clover (Melilotus officinalis) on the antioxidant activities and free radical scavenging by using DPPH (2, 2-diphenyl-1-picrylhy...

The study was conducted at 10 – yearsold walnut orchard at Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni-Solan(H.P.) to find out the effect of integrated nutrient management on leaf nutrient status of walnut (Juglans regia L.). There were 13 different treatment combinations of organic and inorganic fertilizers. Treatments were applied on per tree basis. Among the treatments re...

______________________________________________________________________________ Abstract: Information on soil and leaf nutrient concentrations for black walnut are of value only when they are properly sampled, accurately analyzed, and the results correctly interpreted. Guidelines for interpreting soil and leaf analyses and leaf symptoms are presented along with recommendations for correcting nut...
