Salinity Stress Effects on the Growing Rates of Tomato (Lycopersicon esculentum Mill.)

The objectif of this study was to observe the effect of salinity on the tomato plant’s height, leaf area, root lenght and fruit production. The biological material used in this study was represented by five local races of tomato cultivated in east side of Romania. The seeds was collected from areas with saline soils from Moldavia region and compared with commercial type salt-tolerant tomato. The bifactorial experience was conducted in a pots experiment in randomized blocks with four repetitions. Five tomato genotypes studied were subjected to salt stress for a period of 30 days is constantly wetted with saline solution to a concentration of 100 mM and 200 mM. After 30 days salt stress is manifested difference in the growth rate of the untreated variants as a result of the biological characteristics of each cultivar, but also differences in the variants treated, due to salt stress
