In order to investigate the shucking technology and design the efficient Sheller, it’s highly significant to study on the mechanical characteristics of walnut. The Pro/E software and finite element method was adopted to build the geometry and finite element model of walnut. Afterwards, the walnut stress distribution with different loads was analyzed to seek the optimum force-applying forms whic...

Kazakhstan has very rich walnut genetic resources; however there is no ongoing walnut breeding program. Kazakhstan government has several projects in cooperation with Russia, USA, Bulgaria, Czech Republic and Poland for plant breeding purposes. In the present research walnut genetic resources originated from Jabağıl, Tulkıbas, Sayram, Lenger, and Botanical Garden of International Hodja Ahmet Ye...

walnut is a plant belongs to juglandaceae family. among 21 species, of thejuglans genus, the persian walnut (juglans regia l.) is recognized as the bestspecies. the main aim of the current research work was identification of geneticdiversity among persian walnut species in golestan province, iran. morphologicaltraits used as an approach to evaluate 96 trees which belonged to five nativepopulati...

Samples of apricot pits at 7.61, 12.45, 18.21 and 25.15% (wet basis) moisture contents in the three directions (along length, width and thickness) were subjected to impact energy ranged from 0.2 to 1.1 J using an impact test apparatus. Data obtained on the quantity of fully cracked and unbroken kernel, fully cracked but broken kernel and uncracked pits were used in the computation of the pits c...

BACKGROUND Nuts are one of the main consumed snacks worldwide and also have an important role among Iranian's food habits. Natural contamination of nuts with aflatoxin is unavoidable and causes a special challenge for nuts safety and quality. OBJECTIVES The purpose of this research was to study the aflatoxin contamination in commercially-available nuts (pistachio, walnut and peanut) in the ma...

although self incompatibility in walnut has not been reported, but the dicogamy limits self pollination of walnut cultivars. as the density of female flowers produced by the tree is low, if a high fruit set occurs, yield especially in terminal bearing cultivars will not be high. so breeding of a pollinizer cultivar with proper pollen shading period is highly necessary for increasing fruit produ...

The content of walnut metabolites is related to its nutritive value and physiological characteristics, however, comprehensive information concerning the metabolome of walnut kernels is limited. In this study we analyzed the metabolites of walnut kernels at five developmental stages from filling to ripening using GC-MS-based untargeted metabolomics; of a total 252 peaks identified, 85 metabolite...
