The Effect of Salinity on Plant Growth in Seasonal Flowers
Abstract
In this study, Tagetes erecta L. (Velvet Flower), Petunia hybrida L. (Laughter Flower) and Gazania splendens L. (Gazania, Koyungözü) F1 species were tested under controlled conditions against salt stress (0 mM, 20 mM, 40 mM, 60 mM and 80 mM NaCl). Seeds were germinated in peat; when cotyledon leaves were formed, the seedlings were transplanted into plastic bags containing natural soil. Distilled water is used to prepare the different salt concentrations. Plants were irrigated with 10 ml of saline water at 20 mM, 40 mM, 60 mM and 80 mM NaCl concentrations every day. In order to investigate salt stress tolerance of plants, plant analysis (total fresh weight analysis, stem and root wet weight analyses, analysis of plant height, stem, root and leaf length analyses, analyses of leaf number, stem diameter, and determination of fresh weight ratios) and soil analysis (soil texture, soil acidity, salt content, organic substance analysis, nitrogen, available phosphorus, exchangeable potassium, calcium and sodium levels, available chlorine level) were conducted in laboratory conditions. According to the results of the study, Tagetes erecta, Petunia hybrida, and Gazania splendens were found to be salt tolerant to 40 mM, 40 mM, and 60 mM of salt, respectively. It was shown that concentration of 40 mM NaCl and above for irrigation showed signi cant negative effects for plant growth parameters such as stem diameter, stem length, plant height, root fresh weight, fresh stem weight and concentrations above 80 mM NaCl resulted in death.
