The phenolic extracts of walnut cultivars with a red pellicle (HWE), purple (ZWE) and yellow (WWE) were compared. total contents phenolics, flavonoids condensed tannins, as well in vitro antioxidant activities (ABTS DPPH) the evaluated. results showed that 25 compounds identified three colored walnuts. HWE contained highest phenolics while ZWE content flavonoids. DPPH ABTS assays indicated colo...

Morphological quality of black walnut (Juglans nigra L.) seedlings largely dictates their capacity to establish well in plantations and their performance potential for use as rootstocks in grafting. Larger seedlings and rootstocks, attained from propagation at relatively low nursery sowing densities, have comparatively more expansive root systems for exploitation of soil resources and greater n...

We present a comprehensive analysis of the convergence properties of the frame operators of Weyl-Heisenberg systems and shift-invariant systems, and relate these to the convergence of the Walnut representation. We give a deep analysis of necessary conditions and sufficient conditions for convergence of the frame operator. We show that symmetric, norm and unconditional convergence of the Walnut ...

BACKGROUND Nut consumption is associated with a protective effect against coronary heart disease, partly due to its high antioxidant content. It is hypothesized that the inclusion of nuts in the diet will improve the antioxidant status of subjects with metabolic syndrome who may be vulnerable to impaired antioxidant status. AIM The effects of high cashew nut and high walnut diets on the antio...

In this study, the effects of coatings made of chitosan (Chi) incorporating thyme essential oil (TEO) on lipid oxidation and changing color indexes of walnut kernels were investigated. Chi: pure, in accompany with TEO at concentrations of 500 and 1000 microliter per liter, in an aqueous coating solution, with different packaging methods: Gunny sack, polypropylene and active packaging, compared ...

This study was conducted to seek the opinion of walnut producers on barriers affecting the success of producers to found production cooperatives regarding horticultural products in Tuyserkan Township, Iran. A sample of 234 walnut producers were randomly selected through multistage cluster sampling technique. Descriptive- correlation research method was used in this study which has been implemen...

The objectives of this research are: (1) to evaluate elite Paradox hybrid clones for resistance to Phytophthora citricola, a virulent and prevalent crown and root pathogen affecting California walnuts and (2) to determine specific etiology of a root and crown rot problem in upper Sacramento Valley orchards on Paradox walnut rootstock. Two screens for resistance to P. citricola were completed in...

Thousand cankers disease, caused by the walnut twig beetle (Pityophthorus juglandis Blackman) and an associated fungal pathogen (Geosmithia morbida M. Kolarík, E. Freeland, C. Utley, and N. Tisserat), threatens the health and commercial use of eastern black walnut (Juglans nigra L.), one of the most economically valuable tree species in the United States. Effective phytosanitary measures are ne...

In this study, walnut green husk extract, which is a valuable waste of horticultural products, was used to enhance antioxidant properties and reduce microbial load of ketchup sauce. Extraction efficiency of walnut green husk extract 22.01%, total phenolic compounds 65.40 (mg gallic acid per 100 g dry husk), flavonoids 10.06 (catechin mg per 100 g dry husk), and EC50 0.17 (mg/mL) were expressed....
