Abstract

Bu çal ışma, demir klorozu gösteren şeftali ağaçlar ı n ı n besin maddesi kompozisyonlar ı üzerine klorozun etkisini belirlemek çin yürütülmü ştür. Bu amaçla, 4 şeftali bahçesindeki de ğişik düzeylerde kloroz gösteren a ğaçlardan ayr ı ayrı , 2 y ı l süreyle yaprak örnekleri al ı nm ışt ı r. Araşt ı rma sonucunda elde edilen bulgulara göre; şeftali ağaçları n ı n demirle beslenme durumlar ı n ı n aç ı klanmas ı nda aktif demirin, toplam demirden daha iyi bir paremetre oldu ğu, kloroz ile Ca, Mg, Zn, Cu ve Mn içerikleri aras ı nda bir ilişki bulunmad ığı , ancak P/Fe, K/Fe, K/Ca, Zn/Fe ve Cu/Fe oranlar ı n ı n klorozdan önemli düzeyde etkilendikleri ve bu oranlann Fe klorozunun te şhisi ve kapsam ı n ı n belirlenmesinde kullan ı labileceğ i görü şüne var ı lm ışt ı r

Investigation on Nutrient Contents of Peach Trees Affected by Iron Chiorosis in Bursa Region

Abstract

This study was implemented to determine effect of iron chlorosis on mineral composition of peach trees. For this purpose, leaf samples were taken separately from trees indicating different degree of chlorosis in four orchards in two years period. According to results obtained from the experiment; It was shown that, active iron was the most appropriate method in diagnosis of iron chlorosis as compared with total iron. There was no significant relationship between iron chlorosis and Ca, Mg, Zn Cu and Mn concentrations of leaves, whereas P/Fe, K/Fe, K/Ca, Zn/Fe and Cu/Fe ratios were significantly affected by iron chlorosis and it could be suggested that these ratios wouid be used as an index of iron status of peach trees.

Keywords
