Description
Summary:In order to determine the relationships between salt tolerance, seed and seedling characteristics, 16 watermelon genotypes collected from various regions of Turkey, and 3 standard and 2 F1 hybrid varieties were used as material in the study. The seedlings were grown in Hoaglands nutrient solution in aqua culture in an atmospheric controlled climatic environment, and 100 mM NaCl salt stress was applied when the seedlings had 4-5 true leaves,. It has been understood that watermelon genotypes have different responses to salt stress in seedling growth and ion uptake. The watermelon genotypes 18, 22, 28, 31 and 41, with large seed weights and large cotyledon leaves were less affected from salt damage by being more selective in ion uptake. Watermelon genotypes 33, 38, 39, 40 and 44 with low seed weights and cotyledon leaf weights were not selective on ion uptake and were more affected by salt damage. It has been observed that the parameters used in the study have a high correlation with each other.
