Determination of field performance of some salt tolerant tomato genotypes

Salt tolerance of tomato genotypes when examined through the physiological and morphological, also as agronomic yield and fruit quality characteristics were evaluated and morphological characterization was made according to the criteria of UPOV. The study to monitoring the plant growth; the plant wet and dry weights, stem diameter and length, leaf area index, evaluation of 0-5 scale were examined for revealing salt tolerance in tomato plants; leaf water potential, leaf osmotic potential, leaf temperature, leaf stomatal condactivity, determination leaf chlorosis with SPAD meter, membran injury index, plant Na, K, Ca, Cl, K/Na and Ca/Na contents and using water efficiency parameters investigated as physiological. Furthermore fruit quality characteristics such as total yield, number of fruit, the average fruit weight, fruit diameter and length, fruit hardness, the amount of fruit soluble solid, fruit titratable acidity, fruit vitamin C, fruit pH and EC contents were also investigated. At the end of the study, in terms of resistance to salt all the examined properties such as morphological, physiological and pomological properties were evaluated; 9 tomato genotypes which were selectively taken to trial, among the most tolerant towards their sensitiveness are ranked as Tom23, Tom148, Tom18, Tom209, Tom26, Tom106, Tom150, Tom161 and Tom29.
