Correlation between fruit size and picking scar size in some organically grown highbush blueberries (Vaccinium corymbosum L.)

Abstract

This study was carried out to determine the correlation between fruit size and picking scar diameter of organically grown northern highbush blueberry cultivars. In the experiment, eight northern highbush blueberry cultivars (Toro, Brigitta, Darrow, Patriot, Bluecrop, Bluegold, Bluejay and Chandler) (Vaccinium corymbosum L.), have five years old plants and grows in Trabzon conditions, were used. The differences in the fruit size and the picking scar diameter among the cultivars, and the annual differences within each cultivar were studied. Berry width varied between 14.22 -20.43 mm and fruit weight varied between 1.76 -4.22 g. While Chandler (2.86 -3.14 mm) had the biggest scar size, Patriot and Brigitta (2.14 -2.21 mm) had the smallest scar size. Also, it was determined that picking scar size correlates with fruit width and weight for the harvest year. However, relationship between the fruit width and the scar size of eight cultivars is significantly positive.

Effect of blueberry addition on antioxidant activity, textural, microbiological and physicochemical properties of strained yoghurt

“…The increment in TPC of yoghurts with the addition of different fruits have been observed in many studies (Demirkol & Tarakci 2018). Previous studies in the literature found that the blueberry had strong antioxidant activity (Çelik et al 2013, Liu & Lv 2019, Saral et al 2015, Tagliani et al 2019.…”

“…These results were in agreement with the results of the present study. Previous studies in the literature found that the blueberry showed strong antioxidant activity (Çelik et al 2013, Liu & Lv 2019, Tagliani et al 2019. On the other hand, phenolic compounds such as anthocyanins decomposed in the beginning of the storage period and later gained stability (Wallace & Giusti 2008).…”

“…The a* values of sample BSY12 were higher compared to those of samples C and BSY4 during the storage period, while its b* values were lower than the those of the two samples. The changes in the color parameters of the samples may have been caused by anthocyanins as blueberries are quiet rich in terms of anthocyanins, which are a natural color pigment (Çelik et al 2013(Çelik et al , Ścibisz et al 2012(Çelik et al , Tagliani et al 2019. Similar results were obtained by Cinbas & Yazici (2008).…”
