Abstract

Salinity is an environmental stress that limits growth and development in plants. most SALINITY problems in higher plants are related to increase NaCl. One of the most effective ways to overcome SALINITY problems is the introduction of salt tolerance to crops. Thus in the present study, effect of different SALINITY levels (0, 2, 4, 6, 8, 10, 12 dS/m) on seedling of Lycopersicum esculentum (Dartom native, var. mobil) under hydroponic conditions were studied.Samplings were carried out after four, eight weeks and different parameter including chlrophyll a, b and raw chlrophyll were measured. Statistical analysis of the results was carried out using MSTAT-C and EXCEL soft wares. Results showed that increasing SALINITY levels was correlated to decrease in a, b and raw chlorophyl. Thus increase in SALINITY levels was accompanied with growth decrease. Visible symptoms including dramatic decrease of root and shoot growth and necrose older leaves were also observed in seedlings under SALINITY stress 9 dS/m for native variety and 12 dS/m for mobil variety treatments. TOMATO seedlings tolerance threshold for SALINITY was determined at 8.5, and 11.5 dS/m respectively. At this concentration despite stunted growth, no visible TOXICITY symptoms were observed.
