Abstract

The biochemical responses of some olive cultivars was evaluated to select drought resistant cultivars for olive orchard developing in Iran. One-year-old and two-year-old olive (Olea europaea L.) trees cvs. Mary, Zard, Roghani, Blidi and Mission grown in 14 liter pots containing a mixture of sandy loam soil (62% sand, 24% silt and 14% clay ), were subjected to various levels of water stress. Irrigation treatments were control (soil water at field capacity, ψsoil = -0.03 MPa), mild stress (ψsoil = -0.5 MPa) and severe stress (ψsoil = -1.5 MPa). A factorial experiment based on randomized complete block design was used. Results indicated that the degree of water stress had significant effect on the amount of PROLINe. During of the first experiment, Roghani, Blidi, Mary, Mission and Zard olive cultivars had higher PROLINe content respectively. Increasing of PROLINe content in Blidi, Mary and Roghani olive plants under mild DROUGHT STRESS was higher than other cultivars in greenhouse experiment. Mary, Roghani, Blidi, Zard and Mission olive cultivars had higher PROLINe content under severe DROUGHT STRESS respectively. There was a reduction on PROLINe content after rewatering. It was due to PROLINe instability. Exposure of plants to drought conditions led to noticeable increases in soluble carbohydrate concentration. The amount of soluble carbohydrate increased with increasing of level of DROUGHT STRESS. During of the first and second experiment, Mary, Roghani, Blidi, Zard and Mission olive cultivars had higher soluble carbohydrate content respectively. Plants of Mary, Roghani and Blidi cultivars had significant increase of soluble carbohydrate under mild DROUGHT STRESS in compare with other cultivars. Also, Plants of Mary and Roghani cultivars had significant increase of soluble carbohydrate under severe DROUGHT STRESS in compare with other cultivars. The amount of soluble carbohydrate decreased in the later part of experiment, it may because of use and transport to the roots.
