“…These findings are in alliance with the observations of Ohashi-Kaneko et al (2009) and Chan et al (2007), who found that growing properties of plant were greater in plants, treated with ozonated water than for control. The root respiration by ozonated water might be related to increased biomass productivity of cucumber plants.…”

“…Abdel Nasser (2002) reported that exposure to high ozone concentration (100 ppb) decreased the number and weight of root nodules, water content and leaf area. According to the study on the tomato reported by Ohashi-Kaneko et al (2009), ozonated water did not harm plants (tomato) but did promote their growth. Sterilization by ozonated water might have decreased root rot, consequently increase water and mineral uptake by plant root (Ohashi-Kaneko et al, 2009).…”

“…However, pathogen levels were significantly reduced in all treatments aqueous ozone. Ohashi-Kaneko et al (2009) suggested that ozonated water can be to sterilize of different source water (e.g., drain water, river water, rain water and underground water) in order to control pathogens during the early growth stage of plants. The effects of salt stress and ozonated water on the growth and productivity of vegetables have been studied separately by many authors but the combined effects of ozone and salt stress on cucumber are not yet available in the literature.…”

A B S T R A C TThe main objective of this study was to investigate the effects of water ozonated and salinity on some properties of cucumber. The treatments were defined by a two-factorial design of three water ozonated (0, 0.5 and 1 mg L -1 ) and three water salinity levels (2, 4 and 6 dS mG 1 ). A greenhouse experiment was conducted and after germination, cucumber seeds were grown in pots containing soil, coco peat and perlite and were imposed with water ozonated and salinity treatments. The fruit yield, plant height, stem diameter, total soluble solids and some elements were determined. The results showed that salinity of irrigation water significantly reduced fruit yield and plant height of cucumber. However, statistical testing showed significant increase in total soluble solids with increasing water salinity. Ozonated water increased fruit yield, especially in water salinity 2 dS mG 1 . Also, application of ozonated water caused significantly increases in the plant height. The results also indicated that salinity and ozonated water reduced stem diameter of cucumber, although there were not significant differences. The highest fruit yield (22.76 kg mG 2 ) and plant height (137.2 cm) were obtained at the third level of ozonated water (1 ppm) and 2 dS mG 1 of salinity level. Statistical testing indicated significant increase in concentration of P and Na with increasing water salinity. The application of ozonated water and water salinity caused decreases in concentration of NH 4 . The highest concentration of P (0.41%) and Na (2.76%) were obtained at the third level of ozonated water (1 ppm) and 6 dS mG 1 of salinity level.

In order to investigate the effect of drought stress and ozone on some properties of cucumber, a factorial experiment with complete randomized design was carried out in greenhouse at Khorasgan University, Isfahan, Iran in 2014. Experimental treatments were drought stress including three levels 100% (control), 80% (mild stress) and 60% of field capacity (severe stress) and three ozone concentrations in irrigation water (0, 0.5 and 1 ppm). After germination, cucumber seeds were grown in pots containing soil, cocopeat and perlite and fed with Hoagland solution and were imposed with drought stress and ozone treatments. The fruit weight per pot, stem thickness, ash weight, number of leaf and weight of root (fresh and dry) were determined. The results showed that across the ozone concentrations, drought stress significantly reduced fruit weight, leaf number, dry and fresh weight of root. Also, across the levels of drought stress, statistical testing showed a significant increase in fruit weight with increasing ozone concentrations. However, the highest (91.51 g) fruit weight was obtained at the third level of ozonated water (1 ppm) and 100% FC and for stem thickness (10.2 mm) was 60% FC and without ozone. The highest leaf number (48), fresh weight (6.22 g) and dry weight (2.62 g) of root was revealed at the 0.5 ppm ozone and 100% FC.
