Effect of Water Stress on The Some Evegatif Growth Parameters of Cultivar Grafted on Different Rootstocks 0900 Ziraat Sweet Cherry

38702

Sweet cherry production areas have been increasing in last years and rootstocks which have different growing characteristic are being used. Therefore, responses of new and present rootstocks to water stress must be determined. For this purpose, one year old 0900 Ziraat sweet cherry variety grafted on Mahaleb (Prunus mahalep L.), Mazzard (Prunus avium L.), Ma x Ma 14 (Prunus mahalep L. x Prunus avium L.), CAB 6 (Prunus cerasus L.) ve Gisela 6 (Prunus cerasus x P. canescens L.) rootstocks were used in this study. This study was conducted at Fruit Research Station, Eğirdir, Isparta-Turkey. The trees were planted into 50-liter pots with 1:2:1:0.5 ratio including sandloam soil:peat:manure. During the experiment, four different drought level were applied to all variety/rootstocks combinations (D1: the soil was fully irrigated to reach field capacity in each irrigation, D2, D3 and D4 treatments; the irrigation levels were changed by giving %75, %50 and %25 of irrigation water applied to D1 treatment). Trunk cross sectional area, shoot length, shoot diameter and leaf area growth were affected negatively depending to stress level intensity. The highest decreasing for leaf area and stomatal density were determined in nurseries grafted on CAB 6 and Gisela 6 rootstocks. According to the degree of resistance to water stress, the rootstocks are ranked as Mahalep, Mazzard, Ma x Ma 14, Gisela 6 and CAB 6. If clonal rootstock are used for sweet cherry growing areas where water resources are scarce Ma x Ma 14 rootstocks can be recommended to sweet cherry growers.
