Abstract:

In this study, the effects of ultraviolet B (UV-B) radiation applications on the plant nutrient content in the fittings were studied. This is the case with Solanum melongena L. cv. Anamur F1) fidelities were subjected to control (0 kJ m-2 day-1), 10.8 kJ m-2 day-1 (low dose) and 16.2 kJ m-2 day-1 (high dose) UV-B radiation application for 10 days from the period they were first real-leafed (secondly, 76.5 min day-1 and 114.75 min day-1) period. The study determined the amount of H2O2 in the leaves with nitrogen, potassium, phosphorus, calcium, iron, magnesium, manganese and zinc content in the fide roots and on the surface of the soil. High-dose UV-B application has been shown to cause increased phosphorus content in the fide roots, while low-dose UV-B application reduces upper axis phosphorus content, increased the amount of zinc in the roots and upper axis, and increased nitrogen content is only upper axis.

Abstract:

The aim of the study was to investigate the effects of UV-B irradiation on plant nutrient contents in eggplant (Solanum melongena L) seedlings. Seedlings were subjected to UV-B irradiation 0 kJ m-2 day-1, 10.8 kJ m-2 day-1 and 16.2 kJ m-2 day-1 for 10 days (76.5 min day-1-114.75 min day-1) when they reached to the first true leaves stage. In the study, nitrogen, potassium, phosphorus, calcium, iron, magnesium, manganese and zinc contents in the seedling roots and upper parts of seedlings and the amount of H2O2 in the leaves were determined. It has been determined that high-dose UV-B application causes an increase in phosphorus content in eggplant seedling roots, while low-dose UV-B application increases the amount of zinc in the root and upper parts. The increase in the amount of nitrogen by low-dose UV-B application was obserbed only in the upper part of seedlings.
