“…Pecan consists of 9-18% protein, which is lower compared to other nuts, and it consists of 14% carbohydrate depending on cultivars. Pecans are a fine source of dietary fiber, and they are also rich in terms of minerals including manganese, phosphorus, magnesium, zinc, iron, and naturally low in sodium (Prasad, 1993;Gebhardt and Thomas, 2002;USDA, 2004;Curiel-Maciel et al, 2021). Furthermore, pecans have high oil contents, about 65-70%, depending on cultivars, and the oil profile is mostly comprised of monounsaturated (commonly oleic acid) and polyunsaturated fatty acids (linoleic acid).…”

Pecan is a major horticultural nut tree that originated from North America and, in Turkey, it is generally cultivated in the Aegean and Mediterranean regions. In this study, morphometric traits of twenty-one cultivars grown under equal ecological conditions in the Southeastern region of Turkey were determined. In addition, a multivariate analysis was performed on morphometric traits for determining suitable cultivars that show the best performance in these ecological conditions. The nut weight ranged from 3.66 g for ‘Cherokee’ to 10.35 g for the ‘Shoshoni’ cultivar. The ‘Choctaw’ had the highest kernel weight and kernel ratio ranged from 5.63 g to 58.60%. While the ‘Cherokee’ had the lowest ranging from 0.91 g to 22.84 g, respectively. A significant positive correlation between nut weight and kernel ratio was determined. The kernel weight was also highly correlated with nut weight and height. The use of clustering analysis according to Ward’s method allowed the establishment of relationships between pecan cultivars by separating them into four main clusters. Also, these results were supported with principal component analysis, and ‘Big Z’ and ‘Ideal’ cultivars were determined to be the closest cultivars. Results showed that there are quantitative differences regarding the genetic property of pecan cultivars and more than half of the examined cultivars showed a good performance in terms of nut quality criteria that are crucial in marketing. Furthermore, the multivariate analysis was effective in the differentiation of pecan cultivars and it has been evaluated that it can be used successfully in future studies

To study the effect of exogenous selenium on fruit quality in walnut (Juglans regia L.), 8-year-old walnut (Qingxiang) was taken as the research object. In the fruit expansion stage, 300 mg/L of sodium selenate, yeast selenium and sodium selenite solutions were applied on the leaf of walnut, and the selenium levels in leaves, pericarp and kernel were determined at the ripening stage. The fruit quality, mineral nutrient content, antioxidant enzyme activity, and related genes' expression were analyzed. The results showed that the three exogenous selenium increased the selenium levels in leaves, pericarp and kernel of walnut. They also significantly increased fruit and kernel weights, and kernel linoleic acid, but markedly decreased kernel crude fat and saturated fatty acid. Selenium spraying promoted the absorption of mineral nutrients such as potassium and zinc, but inhibited the absorption of calcium, and had no significant effect on iron and magnesium in the kernel. Three exogenous selenium increased the activities of superoxide dismutase (SOD), peroxidase (POD), ascorbate peroxidase (APX), and catalase (CAT) significantly in the kernel. Except for sodium selenate treatment significantly reduced malondialdehyde (MDA) content in the kernel, the other two selenium sources treatments had no significant effect on MDA and hydrogen peroxide (H 2 O 2 ) levels. They also increased the expression of JrCu/Zn-SOD, Jr2-Cys POD, JrCyt-APX and JrCAT in kernel, to different extents. These implies that, in the walnut fruit enlargement period, the foliar spraying selenium could increase the selenium content of walnut, affect the mineral nutrient absorption, improve the antioxidant capacity and related genes' expression, and reduce the degree of peroxide, and then improve the quality of fruit. Furthermore, yeast selenium showed the comprehensive effect of the best.
