Description:	Tomato is one of the most important agricultural crops in Algeria due to our consumption of it all year round, so we conducted a study related to this product, under salt stress conditions, where several different ncentrations of NaCl salt were used, we applied several treatments(2,5g/l)(5g/l)(10g/l). in the presence of witness S0. Through the obtained results, which are expressed by the studied criteria, it is clear that salinity has negative effects on the growth and development of tomato plants. Salt concentrations led to a decrease in morphological indicators: number of leaves, stem length, weakness in vegetative growth and a decrease in lateral branches, with the appearance of some yellow spots on the leaves, then withering and falling, especially the lower ones, as we noticed stunting of the stem and sometimes the death of some seedlings. And a change in the natomical structure of the legs, which led to a decrease in the thickness of each of: the epidermal layer, the outer cortex, the inner cortex, the circular ocean, the medulla and the transporting vessels. From the results of our study, we conclude that the tomato plant Berner Rose is half sensitive to salt stress during seedling growth.
