In this study, the effects of different levels of irrigation water salinity on vegetative development of 0900 Ziraat sweet cherry variety was investigated. The study was conducted at Eğirdir Fruit Research Station as pot experiment in 2013. One year old nurseries (0900 Ziraat variety) grafted on mazzard (Prunus avium L.) and mahalep (Prunus mahalep L.) rootstocks used commonly for sweet cherry growing in Turkey were used. A mixture (40 kg) of sand+loamy soil+peat+farm yard (1:2:1:0.5 ratios) was placed into 50 liter pots and one year old sweet cherry trees were planted in 50 litre pots. Four different levels of salinity water treatments (T1=0.3 dS m-1, T2=2.0 dS m-1, T3=4.0 dS m-1 and T4=6 dS m-1) were used for both variety/rootstocks combinations as research subjects. The all measurements were done for every 15 days during growing period for determining effects of salinity water treatments on trunk diameter, plant height, shoot length and shoot diameter and periodic alterations were also determined. According to the study, it was determined that vegetative development of sweet cherry trees was inhibited by salinity stress. According to results of vegetative development, it was found that nurseries grafted on mazzard rootstocks (Prunus avium L.) were more sensitive than nurseries grafted on mahalep rootstocks (Prunus mahalep L.). It can be that mahalep rootstock should be used for sweet cherry growing areas which has high irrigation water salinity.
