Changes of micronutrients, dry weight, and chlorophyll contents in strawberry plants under salt stress conditions

Abstract

Various concentrations of NaCl (0, 500, 1000, and 2000 mg/L) were applied to plants of the "Camarosa" and "Tioga" strawberry varieties for 10 weeks. At the end of the experiment, it was determined that the leaf dry weight increased especially at 500 and 1000 mg/L NaCl treatments when compared to control treatment. However, salt applications did not change total chlorophyll content. With the salt applications, iron (Fe) and manganese (Mn) content increased, while copper (Cu) content did not change in the aerial part of plants in both varieties. On the other hand, zinc (Zn) content increased in the "Tioga" strawberry variety. In the root part of plants, Fe, Zn, Mn and contents did Dot change according to salt applications in both strawberry varieties. However, 2000 mg/L NaCl of salt applications increased Cu content in the "Camarosa" strawberry variety significantly.
