Investigation of Micro Element Intake of Potassium (K +) and Salt Stress Applied Pepper Plants

Abstract

This study was carried out in order to determine whether the element of potassium would be effective in the intake of micronutrients of the papper plants under salt stress. In the study, Demre long pepper type was used as material. The study was carried out in 16/8 hour light / dark photoperiod, 25 0C and 70% humid climate room in controlled conditions. After germinating the seeds planted in the pumice, the seedlings formed in 2 real leaves were cultured in hydroponics. Hoagland nutrient solution was used in culture in hydroponic solution. The current Hoagland solution K+ was calculated as 136 ppm and was used as the control. Other doses were K1 = 116 ppm, K2 = 136ppm, K3 = 156 ppm, K4 = 176 ppm. In addition, 100 mM NaCl salt was applied to the plants. Sampling for measurements and analyzes was performed on the 20th day of salt administration. In these samples, iron (Fe+2), zinc (Zn+2), copper (Cu+2), manganese (Mn+) and magnesium (Mg+) contents were determined from micro nutrients by total plant weight. In the results obtained, K3 = 156 ppm and K4 = 176 ppm doses were effective in salvaging the plant from the detrimental effect of salt. © 2018, International Journal of Scientific and Technology Research.
