One of the environmental stresses, and maybe one of these important drought stresses, cause deterioration of oxidative on the plant cell. Beans is one of the vegetables influenced by high level of drought. Drought stress deterioration effects on beans and its aim determines these effects either as been different or not caused by drought stress dependent on 10 item beans (Phaseolus vulgaris L.) variety. To get the hydroponic condition ready in time within 15 days, plant with 10% ratio of polyethyleen glycol (PEG 6000) were used to create drought effects. Bean leaves were harvested 6 days later after PEG implementation and were measured. The amount of lipid peroxidation production and malondyhalheit were directed towards determining the oxidative deterioration and in addition the chlorophyll amount. As a result of drought implementation, Samsun 96 (S96) and Sırık Barbunya (SB) beans genotypes have the most decreased chlorophyll amount than GevaÅŸ Sırık 57(GS57) and Oturak Barbunya (OB) genotypes. At the same time, S96 and SB genotypes have the most increased malondyhalheit (MDA) content than GS57 and OB. Also, of the total ten item of beans variety, GevaÅŸ Sırık 57 and Oturak Barbunya were least affected by drought stress, while S96 and SB genotypes showed more sensitivity to drought stress.
