Abstract
This study was conducted to investigate the effect of foliar Fe applications on leaf Fe and some nutrient (P, Ca, Mg, K, Mn and Zn) concentrations in strawberry (Fragaria vesca L.) cultivars. For this purpose, 2 forms of Fe solutions (FeSO4. 7 H2O and Fe-EDTA) containing 0.28% Fe were sprayed onto the strawberry leaves at 3 growth stages (before blooming, first blooming, full blooming). Depending on the Fe sources, Fe concentration increased after each application. Before blooming, leaf Fe concentration increased from 60 mg kg -1 (control) to 127 and 105 mg kg -1 with Fe-EDTA and FeSO4. 7 H2O, respectively. During the first blooming, leaf Fe concentration continued to increase to 139 mg kg -1 with both Fe sources. While Fe concentration was 87 mg kg -1 with the control treatment, it reached 184 mg kg -1 with Fe-EDTA and 238 mg kg -1 with FeSO4. 7 H2O application after the full blooming. While the leaf Fe and Zn concentrations increased with foliar Fe applications, leaf P, Mg and K concentrations were not affected, but Ca and Mn concentrations decreased. This indicated that the leaf Fe concentration of strawberry increased continuously with repeated foliar Fe application from both sources. Regarding leaf Fe concentrations, it was seen that the effect of FeSO4. 7 H2O on leaf Fe concentrations was higher than that of Fe-EDTA. Ozet: Bu cal›flma, yapraktan Fe uygulamas›n›n, cilek ceflitlerindeki (Fragaria vesca L.) Fe ve baz› (P, Ca, Mg, K, Mn ve Zn) besin elementi konsantrasyonlar›na etkisini araflt›rmak icin yap›lm›flt›r. Bu nedenle, cilek yapraklar›na % 0.28 Fe iceren iki Fe formu (FeSO4. 7 H2O ve Fe-EDTA) 3 farkl› donemde (ciceklenme oncesi, ilk ciceklenme, tam ciceklenme) uygulanm›flt›r. Demir uygulamalar›na bal› olarak yaprak Fe konsantrasyonlar› artm›flt›r. Ciceklenme oncesi yaprak Fe konsantrasyonu Fe- EDTA ve FeSO4. 7 H2O ile 60 mg kg -1 dan 127 ve 105 mg kg -1 'a yukselmifltir. Ilk ciceklenmede yaprak Fe konsantrasyonu artmaya devam etmifl ve 139 mg kg -1 'a ulaflm›flt›r. En yuksek Fe konsantrasyonu tam ciceklenme doneminde elde edilmifl ve kontrol uygulamas›nda 87 mg kg -1 olan Fe konsantrasyonu Fe- EDTA ve FeSO4. 7 H2O uygulamalar› ile 184 ve 238 mg kg -1 'a ulaflm›flt›r. Demir uygulamalar› ile yaprak Fe ve Zn icerikleri artarken P, Mg and K icerikleri deiflmemifl buna karfl›l›k Ca ve Mn icerikleri azalm›flt›r. Elde edilen sonuclara gore cilek yapraklar›n›n Fe icerikleri tekrarlayan yaprak uygulamalar› ile her iki Fe kayna¤›nda da surekli bir art›fl gostermifltir. Elde edilen art›fl oranlar›na gore FeSO4. 7 H2O uygulamas›n›n Fe-EDTA ya gore daha etkili olduu belirlenmifltir.
