The essential oil from the leaves of Juglans regia L. (Juglandaceae) growing wild in Kashmir (India) was obtained by hydro-distillation and analysed during different stages of growth ranging from April to October. The analysis was carried out by a combination of capillary GC-FID and GC-MS analytical techniques. Both qualitative and quantitative differences were observed in the essential oil col...
Leaves from in vitro proliferating shoots of cvs. Chandler and Hartley of Persian walnut were cultured on MS and NN media supplemented with BA and NAA. Three light conditions including darkness, low light intensity and modified light intensity were used. Most of the calli were friable and non-embryonic in all three conditions. Rate of callogenesis depended on cultivar, culture medium, light con...
This multiyear project is aimed at developing a practical solution to managing blackline disease of walnuts in California orchards. Blackline disease in English walnuts is caused by a Cherry leaf roll virus (CLRV) infection of English walnuts (Juglans regia) grafted on black walnuts (J. hindsii) and ‘Paradox’ hybrid (J. hindsii x J. regia) rootstocks. The HR is due to the resistance of black wa...
Objective(s):One strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. Plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. Materials and Methods: Urtica dioica and Juglans regia Linn were tested for α-amylase inhibition. Different concentrations of leaf aqueous extracts were incubated with enzym...
BACKGROUND AND AIMS Kaolin applications have been used to mitigate the negative effects of water and heat stress on plant physiology and productivity with variable results, ranging from increased to decreased yields and photosynthetic rates. The mechanisms of action of kaolin applications are not clear: although the increased albedo reduces leaf temperature and the consequent heat stress, it al...
To better understand carbon (C) sequestration by Juglans regia L. plantations in karst regions of southwest China, this study examined biomass increment and C storage in four different-aged J. regia stands, as well as the distribution of carbon stock among the various ecosystem components. Tree and ecosystem biomass increased with stand age. Aboveground biomass (AGB) represented 64.79% of the t...
Flavonoids are rich in Juglans regia L. leaves. They have potent antioxidant properties, which have been related to regulating immune function and enhancing anticancer activity. Herein, qualitative and quantitative determination of flavonoids from J. regia leaves was carried out using high performance liquid chromatography coupled with tandem mass spectrometry with electrospray ionization and n...
گردوی ایرانی (juglans regia l.) یکی از مهم ترین گونه های جنس juglans است و ایران یکی از مراکز مهم تنوع ژنتیکی آن می باشد. افزایش کمیت و کیفیت این محصول جهت صرفه اقتصادی و دستیابی به بازارهای جهانی از اهداف مهم اصلاح درختان گردو می باشد. تاریخچه طولانی کشت و کار گردو به صورت بذری تنوع شدیدی در درختان ایجاد کرده و سبب افزایش سطح هتروزیگوسیتی ژنوم آن به دلایلی مانند دگرگرده افشانی، دیکوگامی و گرده...
The aim of this study was to assess the phenolic composition and nutraceutical potential of tinctures from fruits in two stages of maturity (F3, younger; F25, older), green husks (GH), and leaves (L) of Juglans regia L. In all extracts gallic, protocatechuic, 3-caffeoylquinic, 3-ρ-coumaroylquinic, 4-caffeoylquinic, 4-ρ-coumaroylquinic, and ρ -coumaric acids and quercetin-3-O-deoxyhexoside were ...
