“…While the exact mechanisms are not fully understood, it can be deduced that carbohydrates play an important role in determining fruit sets, albeit primarily via indirect means. This suggests that carbohydrate content often proves to be a notable limiting factor in the process of fruit set [20]. There is a common agreement that the reproductive and vegetative organs of deciduous tree species are formed and stored at significant rates of carbohydrate requirements from reserves during the initial growth and development.…”

Alternate bearing (AB) is of great importance in horticulture and leads to fluctuations in yield variation. Although AB is a natural phenomenon to optimize resource allocation and improve crop productivity and profitability in plants, understanding the factors that influence AB can help in implementing effective management strategies to reduce the negative effects and promote consistent and sustainable production. This study aimed to investigate the variation in carbohydrate levels in various tissues of both bearing and non-bearing pistachio (Pistacia vera L. cv Uzun) trees during different periods of growth development in two consecutive years to gain a deeper understanding of their potential contribution to AB. Twelve 34-year-old pistachio trees, consisting of six “ON” and six “OFF” year trees, were accidentally selected from a pistachio orchard. The “OFF” year trees were induced two years before sampling to be in the “OFF” year state by artificially removing flower buds. Sucrose was the main soluble sugar in the different parts of the pistachio tree studied. In general, the amount of sugar was higher in the non-bearing year than in the bearing year. It was found that non-structural carbohydrates of trees decreased between June and July, resulting in flower buds to abscise. The amount of carbohydrates decreased during nut development in “ON” trees, indicating the possible role of carbohydrates in AB.

“…In recent years, fruits have become increasingly popular as an important source of antioxidants. Thousands of biochemical compounds with different properties, quantities, and functions have been identified in some fruit species including berry species (Ergun & Zarifikhosroshahi, 2020;Gündeşli, 2020). Berry fruits attract attention due to their beneficial effects on human health.…”

In this study, six berry fruits; goji berry/wolfberry (Lycium barbarum), black mulberry (Morus nigra), white mulberry (Morus alba), blackberry (Rubus fructicous L.), purple mulberry (Morus rubra) and Bursa Black mulberry (unknown) were analyzed by HPLC-FD to determine whether they present melatonin. The melatonin was detected different amounts in all samples. Besides, the total phenolic content and antioxidant capacity were studied in all fruit samples. DPPH and ABTS tests were applied to determine the antioxidant capacity. It was observed that the amount of melatonin in the fruit samples varied between 123.44 and 1600.48 ng/gFW. It was found that the concentration of melatonin in goji berry (BF1) was higher than other berry fruits. The highest total phenolic content and antioxidant capacity to were obtained from purple mulberry (BF6) as 276.83 mg GAE/100 gFW, 452.38 mg TE/100 gFW (DPPH) and 555.73 mg TE/100 gFW (ABTS), respectively. Results reveals a significant positive correlation between the total phenolic content with antioxidant capacity.
