“…A considerable genetic variation of the measured traits has been found among native seedling trees. As reported by Cosmulescu et al [13], fruit weight ranged from 7.6 to 20.9 g, fruit length from 31.2 to 53.6 mm, fruit diameter I from 24.8 to 37.5 mm and fruit diameter II from 23.6 to 36.2 mm.…”

“…Nowadays, although there are walnut orchards in areas favorable to their cultivation, most walnuts trees in Romania are still found through vineyards, old orchards, road alignments and village fencing, which makes it difficult to maintain trees but also to obtain a large fruit crop. Many Romanian researchers consider that the important phenological and tree characteristics were found in the native trees that have seedlings origin [11][12][13][14].…”

Physical, Nutritional and Functional Properties of Walnuts Genotypes (Juglans regia L.) from Romania

Walnut (Juglans regia L.) is the oldest fruit grown in the world and grows spontaneously almost throughout Romania. In this study, the physical properties and chemical composition of twenty types of walnuts from three different locations in Romania were studied. The physical analyzes that were performed were: walnut dimensions and shape properties (nut diameter, nut length, nut shape and nut size), fruit properties (walnut weight, walnut kernel weight and percentage of kernel) and external properties of walnut (walnut kernel extraction, kernel color and shell roughness). The proximate chemical composition (content of water, ash, lipids, proteins and carbohydrates) was determined by standardized AOAC methods, while fatty compounds were determined by GSMS. Water content ranged from 1.23% to 5.00%, mineral content between 1.31% and 2.49%, lipids content between 56.09% and 66.56% and protein content ranged between 12.73% and 20.413%. Based on these, the carbohydrate content and nutritional value of the 20 walnut samples were calculated. In all samples, saturated palmitic acid (C16:0) and stearic acid (C18:0) as well as unsaturated oleic (C18:1), linoleic (C18:2) and linolenic (C18:3) fatty acids were determined. A statistical analysis was also performed correlating the results obtained from the chemical analyzes of the walnuts.
