Walnut, Juglans regia L., is known for its insecticidal activities to a range of herbivores and microbes. Isolation and identification of bioactive compounds from walnut is a potential approach for the development of new pesticides. Laboratory experiments were carried out to investigate the acaricidal activities of green husk extracts of walnut. Bioassay-guided fractionation of petroleum-ether ...

Simple sequence repeat (SSR) markers were used to authenticate ramets of 11 Persian walnut ( Juglans regia L.) varieties. All varieties and 28 their (n = 39) genotyped with 17 SSR markers. The genetic profiles revealed two off-types: the Serr 4 (S4) Vina 1 (V1). fingerprints individuating possible using 13 polymorphic SSRs that could be in future identify clones these Except for ‘Chandler’, eac...

The present study was carried out to investigate the yield, quality, and metabolomic responses of four different vegetable crops treatments with pure juglone standard walnut (Juglans regia L.) leaf extract at soil concentrations found in orchards. A total 60 phenolic compounds were identified quantified, some for first time these crop vegetables. Beta vulgaris L. Lactuca sativa less susceptible...

Bud break pattern is a key determinant of tree architecture. The mechanisms leading to the precedence of certain buds over the others are not yet fully explained, but the availability of soluble sugars may play a significant role, especially those in the xylem sap at the onset of the growing period. Here, we measured carbon availability in the different tissues (bud, xylem and bark). To assess ...

In vitro micropropagation is already a current multiplication tool for walnut self-rooted cultivars and rootstocks, but grafting still performed in the field or greenhouses, mainly using seedlings as rootstocks. The present work describes new approach to obtain clonal walnut-grafted plants, involving shoot production of ‘Paradox’ (Juglans hindsi × Juglans regia) cl. ’Vlach’, be used rootstock, ...

The Persian walnut (Juglans regia L.) is one of the most valuable resources in Iran because of its multi benefits. The present study was conducted in Meshkin-Shahr in Ardabil province to investigate the important quantitative and qualitative characteristics of 31 walnut genotypes. Classification of genotypes was analyzed using the cluster method. The results showed that among selected walnut ge...

Common walnut (Juglans regia L) is an economically important species cultivated worldwide for its high-quality wood and nuts. It is generally accepted that after the last glaciation J. regia survived and grew in almost completely isolated stands in Asia, and that ancient humans dispersed walnuts across Asia and into new habitats via trade and cultural expansion. The history of walnut in Europe ...

background methicillin-resistant staphylococcus aureus (mrsa) is considered a major cause of nosocomial and community infections. its prevalence varies from country to country, even between hospitals of a country. these bacteria often have multi-resistance and can be difficult to treat. objectives the current study evaluated the effect of hydroalcoholic extract of the stem bark of juglans regia...

The present study was focused to evaluate the phytochemical screening and biochemical estimation of ethanolic aqueous extracts edible nuts Arachis hypogea, Anacardium occidentale, Prunus dulcis Juglans regia. showed presence carbohydrate, protein, phenol tannin, flavonoid, glycoside, steroid, alkaloid in all studied nuts. quantification A. hypogeae, P. J. regia were performed determine total am...
