The effect of carbohydrate levels on yielding and fruit quality of 0900 ziraat sweet cherry variety grafted on different rootstocks

This study was carried out to determine the correlation of Gisel ?A 5 (Gi.148/2), İdris (Prunus mahaleb L.) and ?Kuş kirazı (Prunus avium L., Mazzard)? that grafted with 0900 Ziraat cherry in Çanakkale ?Lapseki region between 2006-2007 years. For this purpose, the changing of during the resting period, budding, carbohydrate contents and fruit quality were evaluated. The measurements and analysis were done in Çanakkale Onsekiz Mart University Faculty of Agriculture Department of Horticulture.In this research, during the winter in dormancy period between September ?March; invert sugar, total sugar, and starch contents, the contents of chlorophyll in the leaves during the maturity period and largness of fruits, skin color, flesh color, fruit firmness, soluble solids concentration, stem length, stem thickness and color of stem characteristics obtained in the harvest.There was a differences on carbohydrate contents of rootstocks. Negative correlation was fixed between starch content and invert sugars during dormancy period.. Generally it has been fixed that while starch concentration was reduced, sugar content was increased however this changing differ due to the rootstocks. Between Autumn to winter, an important increasing in carbohydrate content was determined according to the rootstocks. The chlorophyll content in leaves differed due to the rootstocks. Furthermore it is fixed that the chlorophyll content in the leaves of ?0900 Ziraat? variety grafted on ?Mahaleb? rootstock was more than the others. In the consideration of pomological characteristics an important difference between rootstocks was observed.Key words: Cherry, 0900 Ziraat, rootstock, carbohydrate, productivity, fruit quality.
