Preliminary screening of tomato cultivar Edkawy (which grows in the El-Bosaily area of northern Egypt) for salt tolerance was carried out using a hydroponic drip irrigation system, allowing precise control of the nutrient conditions within the root zone. After measuring growth analysis parameters at weekly harvests no significant difference was observed between relative growth rate and net assimilation rate when comparing salt treated and control plants. Concurrent to the screening studies, Pyrolysis Mass Spectrometric was used to analyse fruit ripening and assess quality of samples of fruits from a UK grower (all samples were of the same cultivar, from the same row in a single greenhouse). The technique enabled the separation of tomatoes in relation to ripening method. The combination of these methodologies to study the effect of salinity and postharvest conditions on fruit quality is considered.
