Walnut, Juglans regia L. is the most economically important member of the Juglandaceae family and is the most valuable nut crop in the world. Recently, it has increased greatly in acreage and in production. Although a number of research programs about plant apomixis have been carried out around the world, few were representd by the Juglandaceae. This paper presents a brief review of the current...

In the rapidly developing modern society, many raw materials, such as crushed limestone and river sand, which are limited, are consumed by the concrete industry. Naturally, the usage of waste materials in concrete have become an interesting research area in recent years, which is used to reduce the negative influence of concrete on the environment. Hence, this paper presents the development of ...

INTRODUCTION Falls are the second most common cause of injury-associated mortality worldwide. This study aimed to analysis the injuries caused by falls from walnut tree and assess their mortality and morbidity risk. METHODS This is a retrospective hospital-based study of patients presenting to emergency department (ED) of Ahi Evran Univercity between September and October 2012. For each casua...

In the paper, we investigate relationship between walnut fruit quality and leaf-to-fruit ratio (LFR). The LFR had a significant effect on physical of walnuts (P < 0.05), volume, fresh weight, dry nut weight kernel increased with an increasing LFR. However, no crude protein fat contents > 0.05). number cells per unit area cross-sectional green husk 5L : 1F were significantly higher than those 1L...

We investigated the composition of free amino acids in walnut (Juglans regia L.) seeds (embryo and cotyledons). We also examined xylem transport of free amino acids in young seedlings grown in the absence of external nutrients. A relatively high concentration of free alanine was found in seed tissue, whereas a relatively high concentration of citrulline was detected in young seedlings. Citrulli...

Crown gall of walnut (Juglans sp.), caused by the bacterium Agrobacterium tumefaciens, greatly impacts the CA walnut industry. To determine the genetic diversity of A. tumefaciens throughout the Central Valley of CA, we collected isolates from ten walnut growing counties. A total of 340 A. tumefaciens biovar 1 isolates were collected and tested for the presence of the Ti plasmid by PCR; 190 iso...

To alleviate resource shortage, reduce the cost of materials consumption and the pollution of agricultural and forestry waste, walnut shell composites (WSPC) consisting of walnut shell as additive and copolyester hot melt adhesive (Co-PES) as binder was developed as the feedstock of selective laser sintering (SLS). WSPC parts with different ingredient proportions were fabricated by SLS and proc...

Several North American walnut species (Juglans spp.) are threatened by thousand cankers disease which is caused by the walnut twig beetle (Pityophthorus juglandis Blackman) and its associated fungal plant pathogen, Geosmithia morbida M. Kolarík, E. Freeland, C. Utley and N. Tisserat sp. nov. Spread of this disease may occur via movement of infested black walnut (Juglans nigra L.) wood. This stu...

Diabetes leads to reproductive dysfunctions by producing free radicals. It seems that using walnut can be effective in the damage induced by diabetes. The aim of the present study was to evaluate the effects of walnut consumption on sex hormones in diabetic Wistar male rats induced by STZ (streptozotocin). Diabetes animals were induced by STZ (60 mg/kg). Rats were randomly divided into 5 groups...

Pistillate flower abortion (PFA) is the loss of nut-producing pistillate flowers early in the season, typically 2 to 3 weeks after bloom. PFA is the principal factor limiting productivity in ‘Serr’ walnut while affecting other cultivars to lesser and varying degrees. Research by Vito Polito at UC Davis showed that excessive pollen tubes growing down the style of the walnut pistillate flower pro...
