Description
Summary:Salt stress is one of the most serious environmental problems limiting productivity of crop plants. Cropping system under greenhouse conditions causes osmotic problems to roots due to water and fertilizers supplied through fertirrigation, with a consequent salt accumulation around the root-zone. The aim of the present research was the evaluation of the effects of NaCl-salinity on some fruit quality characteristics of four tomato (Lycopersicon esculentum Mill) hybrids. The study was carried out under greenhouse conditions in Tunja/Colombia. Plantlets of hybrids Supermagnate F1, Marimba F1, Gloria F1 and Astona F1 growing on 3.5kg pots filled with soil were exposed to 40 or 8 mM NaCI. Control plants were untreated. These corresponded to electrical conductivities of 5.2 or 8.8 dS.m-1 respectively and 1.8dS.m-1 for controls. Pots were irrigated twice a week and the water excess was avoided. Results showed that percentage of protein, fibre, fat and carbohydrates were higher in fruits of NaCl-treated plants than in those of control plants, while ash and water contents were reduced by salinity. There were not statistical differences between the hybrids nor within the interaction hybrid x salinity.
