“…In our samples their amount ranged from 4.90 to 9.02 % and from 1.55 to 3.68 % respectively. These ranges were larger than those reported by other authors for hazelnut accessions and hybrids (Cristofori et al 2008;Xu and Hana 2010); nevertheless their mean values were in agreement with those indicated by the cited authors.…”

“…Many nut quality characteristics of different hazelnut cultivars and genotypes have been previously identified in Turkey (Balta et al 2006;Alasalvar et al 2009), United States of America (Mehlenbacher et al 1990a, b), Italy (Tombesi et al 1994;Botta et al 1997;Cristofori et al 2008), France (Germain and Sarraquigne 1997), Slovenia Š tampar 1997, 2011), Spain (Rovira et al 1997), Romania (Turcu and Botu 1997) and Portugal (Amaral et al 2006a;Silva et al 2007). However the results are generally referred to a limited set of accessions or cultivars from specific areas of cultivation.…”

Fatty acids and alpha-tocopherol composition in hazelnut (Corylus avellana L.): a chemometric approach to emphasize the quality of European germplasm

In the frame of SAFENUT AGRI GEN RES Action, which was a European strategy for the recovery, characterization and conservation of genetic resources, the fatty acids and the tocopherol profiles of a set of 75 hazelnut accessions were analyzed. The aim of this study was to assess the genetic differences among the European germplasm, contributing to the definition of nut quality in traditional European areas of cultivation. Significant differences were found between accessions for oil amount and contents of most fatty acids. As expected, monounsaturated fatty acids made up the largest portion (mean 80.85 %) followed by polyunsaturated fatty acids (10.70 %). The saturated ones were the minor components and accounted for only 8.43 % of the total fatty acids. On the basis of Student's test, significant differences between the 2 years of harvest were found for fatty acid content, except for linoleic acid, the ratio of polyunsaturated, a-tocopherol and the stability index. When the oil content was studied in cultivars from the same site of cultivation, the mean values of the genetic pools from central Italy (60.8 %), Slovenia (59.3 %) and Portugal (58.2 %) showed highest values than those of cultivars grown in Greece (56.8 %), Spain (55.9 %) and France (51.5 %). A chemometric approach based on principal component and clustering analyses was developed to identify the most interesting cultivars for breeding programs.

“…Bollwiller' and C. colurna. Similar levels for one or both extremes have been previously reported [Bostan and Đslam 1999, Yao and Mehlenbacher 2000, Silva et al 2007, Cristofori et al 2008, Solar and Stampar 2009, 2011. In general, the difference in kernel percentage among cultivars is due to shell thickness, the cultivars with thin shell gave more kernel and vice versa [Aziz et al 2007], which confirmed our results.…”

Nut and kernel size, shape and some sensorial traits in ten hazelnut (Corylus avellana L.) cultivars were evaluated using an objective procedure based on multivariate analysis in order to obtain an important value of these cultivars for growers, processing and consumers. Cultivars were compared with nuts and kernels of C. avellana L. and C. colurna L. Significant differences in all physical properties were found among the cultivars, and also among cultivars and hazelnut species. A high correlation was found among some hazelnut traits. Cluster and principal component analysis supported results obtained by analysis of variance, and segregated genotypes in similar groups according to their characteristics evaluated. Procedure described may be useful in analyzing impacts of genotype per se on nut and kernel physical and sensorial properties, and also determine the factors for growers, breeders, especially for harvesting, sorting and other postharvest operations in order to establish optimal machine and equipment design.

“…Hazelnut fruits are different in morphologic characteristics and mineral composition with an extremely high variability among genotypes of different origins (Ferreira et al, 2010;Rovira et al, 2005). They are a rich source of main nutritive matter that seem to have positive effect on human health (Cristofori et al, 2008;Oliveira et al, 2008;Schmitzer et al, 2011;Silva et al, 2007). Regarding mineral composition, Alasalvar et al (2003) considered that the major minerals in hazelnut were potassium, phosphorus, calcium, magnesium, and selenium.…”

Hazelnuts (Corylus avellana L.) have a significant place among the types of dried nuts in terms of nutrition and health owing to their special composition of fats, protein, carbohydrates, vitamins, minerals, dietary fibers and phenolic antioxidants. Different hazelnut cultivars grown in Romania ('Cozia' , 'Romavel' , 'Valcea 22' , 'Roverd' and 'Red Lambert') were evaluated for their mineral composition. Microelements were determined by using ICP-MS and a Flame AAS. The average microelements concentrations in the cultivars have varied in the following ranges (mg 100 g -1 ): K, 591.75 -639.13; P, 300.67 -455.06; Mg, Ca, Mn, Fe, Cu, Zn, Cr, Na, Al, Sr, Rb,. According to the daily microelement requirements, the quantity of 100 g hazelnut provided approximately 13% for K, 55% for P, 70% for Mg, 10% for Ca, 94% for Fe, 22 for Zn and 5.6% for Cr of the RDA. These results indicated that hazelnuts are a rich source of a number of important micro-elements and hazelnut can be an important source of microelements for human nutrition and health.
