Effect of some clonal rootstocks on growth and earliness of '0900 Ziraat' sweet cherry.

摘要

The importance of sweet cherry (Prunus avium L.) production in Turkey recently has increased very sharply. To solve rootstock problems and increase cherry yield and quality in a modern and economical way, trials were conducted at six locations using P. avium, 'Gisela 5', 'MaxMa 14', 'Weiroot 158', P. mahaleb (L.) 'SL 64' and 'Tabel' (Edabriz) as rootstocks, '0900 Ziraat' as the main cultivar, and 'Bigarreau Gaucher' and 'Stark's Gold' as pollinizers. The results at Yalova will be presented here. The planting distance was 5x3 m, the design was a randomised block with four replicates and 4 trees per plot, and irrigation was by a drip system. The growing habit and bearing habit differed among the rootstocks in the early years of the experiment. 'Gisela 5' seemed to be the most precocious, followed by 'Tabel' (Edabriz). Fruit size and total soluble solids were not affected significantly by rootstock.
