Effect of Plant Growth Regulators on Fruit Quality and Biochemical Content of '0900 Ziraat' Sweet Cherry Cultivar

Bu çalisma, Gisela 5 anaci üzerine asili '0900 Ziraat' kiraz çesidinin (Prunus)avium)L.) meyve kalitesi ve biyokimyasal içerigi üzerine hasattan 3 hafta önce uygulanan metil jasmonat (MeJA) ve aminoetoksivinilglisinin (AVG) etkisini belirlemek amaciyla Tokat ekolojik kosullarinda yürütülmüstür. Çalismada, 100 ve 200 mg L-1 AVG ile 2240 mg L-1 MeJA dozu kullanilmistir. Kontrol ile karsilastirildiginda, meyve agirligi hem 100 mg L-1 AVG dozu hem de MeJA uygulamasi, geometrik çap yalnizca MeJA uygulamasi ile önemli düzeyde artmistir. Hâlbuki et sertligi, yalnizca MeJA uygulamasi ile önemli düzeyde azalmistir. Et / çekirdek orani hem 100 mg L-1 AVG dozu hem de MeJA uygulamasi ile artmistir. L* ve hue açisi 200 mg L-1 AVG uygulamasi, kroma degeri 100 mg L-1 AVG uygulamasi ve a* degeri her iki AVG uygulamasi ile önemli düzeyde artmistir. MeJA uygulamasi, SÇKM ve pH degerini önemli düzeyde azaltmis, aksine TA degerini artirmistir. Toplam fenolik bilesikler ve toplam antosiyanin, 100 mg L-1 AVG ve MeJA uygulamasi ile toplam antioksidant kapasitesi ise yalnizca MeJA uygulamasi ile önemli düzeyde azalmistir.This study was carried out in Tokat ecological conditions to determine the effect of methyl jasmonate (MeJA) and aminoethoxyvinylglicine (AVG), applied 3 weeks before anticipated harvest date, on fruit quality and biochemical content of 0900 Ziraat sweet cherry (Prunus avium L.) grafted on Gisela 5 rootstock. In the study 100 and 200 mg L-1 AVG doses, and 2240 mg L-1 MeJA dose were used. Compared to control treatment, the fruit weight significantly increased with 100 mg L-1 AVG and MeJA treatment. Geometric diameter significantly increased with only MeJA treatment, whereas, flesh firmness significantly decreased with only MeJA treatment. The flesh / stone ratio increased with 100 mg L-1 AVG and MeJA treatment. L* and hue angle with 200 mg L-1 L AVG, chroma value with 100 mg L-1 AVG, and a* value with both AVG treatment significantly increased. The soluble solids concentration and pH value significantly decreased with MeJA treatment, whereas, the titratable acidity increased with MeJA. Total phenolic compounds and total anthocyanin significantly decreased with 100 mg L-1 AVG and MeJA treatment. The total antioxidant capacity significantly decreased with only MeJA treatment
