In this study, the effect of yeast solution doses of 5ppm, 10ppm, 15ppm
on blackberry quality in chester variety in a 4-year-old blackberry orchard at
Eskişehir Osmangazi University was monitored. Trial; It was determined in four
different doses: control, 5 ppm, 10 ppm, and 15 ppm; Five plants were randomly
selected for each application. Samples were analyzed for biochemical
substances. According to the findings, the highest values were obtained in the
control group in SCCM, TEA, anthocyanin and total flavonoid analysis
measurements. The best value was obtained in the measurement of fruit outer
color (L*a*b*) at a dose of 5 ppm. The highest value was obtained in the vit-C
analysis measurement at the 10 ppm dose. At a dose of 15 ppm, the highest value
was obtained in the analysis of width, weight (3 grains), pH and antioxidant
and total phenolic substances. The results suggest that yeast application can
be a potential bio-fertilizer alternative by increasing the fruit yield and
quality of blackberry fruits. This study is a part of Melih Can GÜLER's
master's thesis prepared under the supervision of Volkan Okatan. The study was
supported by Eskişehir Osmangazi University Scientific Research Projects
Coordination Unit. Project code: FYL-2025-3369 Project code: FYL-2025-3369.
