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.

Özet

Bu çalışmada, Ultraviyole B (UV-B) ışın uygulamalarının patlıcan fidelerinde bitki besin maddesi içeriğine olan etkileri araştırılmıştır. Bu amaçla patlıcan (Solanum melongena L. cv. Anamur F1) fideleri, kontrol (0 kJ m-2 gün-1), 10.8 kJ m-2 gün-1 (düşük doz) ve 16.2 kJ m-2 gün-1 (yüksek doz) UV-B ışın uygulamasına ilk gerçek yapraklı oldukları dönemden itibaren 10 gün (sırasıyla, 76.5 dk gün-1 ve 114.75 dk gün-1) süre ile tabi tutulmuşlardır. Araştırmada fide köklerinde ve toprak üstü aksamda azot, potasyum, fosfor, kalsiyum, demir, magnezyum, mangan ve çinko içerikleri ile yapraklardaki H2O2 miktarı belirlenmiştir. Yüksek doz UV-B uygulamasının patlıcan fide köklerinde fosfor içeriğinin artışına sebep olduğu, düşük doz UV-B uygulamasının ise üst aksam fosfor içeriğini azaltırken, kök ve üst aksamlarda çinko miktarını arttırdığı, azot miktarındaki artışın ise sadece üst aksamda olduğu görülmüştür.
