BACKGROUND The production of nanoparticles using a biosystem is considered green chemistry. Application of plant extracts as a biological process has been proven to be suitable for synthesis of nanoparticles. OBJECTIVES This study designed in order to evaluate the production of silver nanoparticles using Juglans regia leaf extract and to compare the outcome of different preparation methods of...

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...

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...

______________________________________________________________________________ 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...

Leaf extracts of the walnut, Juglans regia L., were evaluated under laboratory conditions to determine their acaricidal activity on the mites Tetranychus cinnabarinus (Boisduval) and Tetranychus viennensis Zacher (Acari: Tetranychidae). Extracts had both contact and systemic toxicity to these mites. The four solvents tested for preparing crude extracts were petroleum ether, chloroform, ethyl ac...

abstract background and purpose: in traditional medicine, herbal products still remain the principal source of pharmaceutical agents. the present study aimed to investigate the antifungal effects of echinophora platyloba and rosmarinus officinalis extracts on c. albicans species. materials and methods: the aqueous and ethanolic leaf extracts of e. platyloba and r. officinalis, collected from th...

in this study, antifungal property of olive leaf extracts against candida albicans ptcc-5027 was examined. fresh olive leaf extracts were prepared using distilled water in a soxhlet apparatus. the antifungal activity of the extract was analyzed by measuring the minimum inhibitory concentration (mic) and minimum fungicidal concentration (mfc), using the microdilution test and disc diffusion assa...

Shallow bark canker incited by Brenneria nigrifluens is considered one of the most dangerous diseases which can cause a significant reduction in walnut and timber production.  During spring and summer of 2019, walnut gardens were surveyed for symptoms like leaf spot, fruit, and stem canker from four different regions of Golestan province located in Iran. A set of 11 Gram-negative bacteria were ...
