Correlating the mass of walnut fruit to some physical characteristics CIGR Journal
Shahbazi, Feizollah.
Physical characteristics of fruits and vegetables and their relationships are necessary for the design of some postharvest processing systems such as handling, sorting and packaging machines and reducing the processing costs. For proper design of grading systems, important relationships between the mass and other properties of fruits such as length, width, thickness, volumes and projected areas must be known. The aim of this research was to measure and present some physical properties of walnut fruits. In addition, walnut fruit mass was correlated to measured physical properties using linear, the Quadratic, S-curve and power models as three different classifications: (1) single variable regressions of walnut dimensional characteristics; (2) single variable...

Proximate composition, minerals and fatty acid composition of Juglans Regia L. genotypes and cultivars grown in Turkey BABT
Yerlikaya,Cemile; Yucel,Sevil; Erturk,Ümran; Korukluoğlu,Mihriban.
The proximate composition of eleven walnut (Juglans regia L.) genotypes (28 ŞK 010, 28 ŞK 055, 28 ŞK 041, 28 ŞK 601, 28 ŞK 925, 28 ŞK 028, 28 ŞK 118, 28 ŞK 350, 28 ŞK 930, 28 ŞK 850, 28 ŞK 036) and three walnut cultivars (Şebin, Bilecik, Kaman 1) produced in Turkey were determined. The oil content of the samples ranged from 61.32 to 69.35%, corresponding to an energy value of approximately 710 kcal per 100 g of kernel. The protein content ranged from 10.58 to 18.19%, and the carbohydrate composition was between 9.05 and 18.92%. The ash content ranged from 1.53 to 1.99%, and the moisture content of the kernels was between 1.91 and 4.48% the oleic acid content of the oils ranged from 17.90 to 33.35% of the total fatty acids. The linoleic acid content ranged...

Effect of Culture Medium in Callogenesis from Adult Walnut Leaves (Juglans regia L.) Chilean J. Agric. Res.
Avilés,Fabiola; Ríos,Darcy; González,Ricardo; Sánchez-Olate,Manuel.
To define preliminary aspects of walnut (Juglans regia L.) callogenesis in indirect propagation systems, this work analyzed callogenic induction in adult leaves of walnut in broadleaf trees (BTM), Murashige and Skoog (MS) Driver Kuniyuki Walnut (DKW) and Woody Plant (WPM) media. Leaf segments of 1 cm², previously sterilized, were placed in each culture medium, supplemented with 21.4 µM naphtalene acetic acid (NAA) and 8.8 µM 6-benzylaminopurine (BAP). A completely random design was used; the experimental unit was a Petri dish with six callus explants. Each treatment was composed of seven Petri dishes. Callogenesis (%), nodular calli (%) and histology of calli explants were evaluated at 4 weeks by staining 10 µm slices with safranine-fastgreen. There were...

Body mass and wing geometric morphology of the codling moth (Lepidoptera: Tortricidae) according to sex, location and host plant in the region of Maule, Chile Ciencia e Investigación Agraria
Torres,Fabiola; Rodríguez,Marcela A; Lavandero,Blas; Fuentes-Contreras,Eduardo.
Codling moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae), is the key pest of apple and walnut production worldwide. Among other variables, successful management of this pest is dependent on adult dispersal at the local scale. Body mass and wing geometric morphology were evaluated on female and male codling moth adults collected from apple and walnut trees in three localities of the Region of Maule. Codling moth adults were obtained by rearing diapausing larvae collected from the field. Newly emerged adults were killed, and the total dry weight, thorax weight and abdomen weight were calculated. The wings were cleared and mounted for morphometric analyses: 15 and 11 characteristics of the fore and hind wings, respectively, were measured, including the...

Comparative study of functional properties of eight walnut (Juglans regia L.) genotypes Ciênc. Tecnol. Aliment.
CERİT,İnci; SARIÇAM,Ayşe; DEMİRKOL,Omca; ÜNVER,Hülya; SAKAR,Ebru; COŞANSU,Serap.
Abstract Eight walnut (Juglans regia L.) genotypes were assessed for the glutathione (GSH) and total phenolic contents (TPC), as well as their antioxidant capacities. The GSH contents were between 1.1 and 7.2 mg 100 g-1. The TPC contents ranged from 33 to 50.3 mg GAE g-1, while the ferric ion reducing antioxidant power (FRAP) values ranged from 156 to 302 mg FeSO4 g-1. A strong correlation (r2=0.8258) was determined between the FRAP values and the TPC. Cupric ion reducing antioxidant capacity (CUPRAC) values ranged from 13 to 35 mg trolox g-1. The correlation between the CUPRAC values and the GSH contents was weak (r2=0.2069). The walnut extracts (0.2 mg mL-1 concentration) showed 16.2-40% DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging activity. A strong...

The Effect of Walnut on the Weight, Blood Glucose and Sex Hormones of Diabetic Male Rats International Journal of Morphology
Ghorbani,R; Mokhtari,T; Khazaei,M; Salahshoor,M. R; Jalili,C; Bakhtiari,M.
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 (n=6), including normal diet and healthy (Sham), Diabetic by normal diet (control) and diabetic by 6, 9 and 12% walnut in their diet (experimental groups), and were examined for 6 weeks. Body weight, blood glucose (3 times), and sex hormones (testosterone, FSH and LH) were measured. Overall, in terms of the mean index, there was a significant difference in the...
