Abstract: This experiment was conducted at Fruit Research Institute, MAREM, Eğirdir-Isparta, Turkey to detect the effects of drought stress on young pear trees in 2017.Deveci, Ankara and Margarita pear varieties grafted onto OHxF 333 rootstocks were used.The young pear trees were one year old and they were planted into 18-litre pots with 1:1:0.5 ratio of soil:peat:manure.During the experiment, three different water stress level were applied to all trees D0: the soil was fully irrigated to reach field capacity in each irrigation, full irrigation, no stress; D1: 50% of D0, moderate stress; D2: 25% of D0, severe stress.Drought stress treatments were applied from July 3 to September 11 2017.Photosynthesis (Pn) and stomatal conductance (gsw) measurements were performed three times after starting drought stress applications.Trunk diameter and leaf area were measured as vegetative development.SPAD measurements were also measured three times during experiment.All pear varieties were affected by drought stress but Deveci variety was determined to be a variety more resistant against to drought stress according to Ankara and Margarita varieties.Ankara and Margarita varieties had similar response to drought stress.
