Effect of salinity on citrus

Turunçgiller tuza karşı hassas bitkilerdir. Dünyanın birçok bölgesinde tuzluluk turunçgil üretimini önemli şekilde sınırlandırır. Tuzlu sulama suyu turuçgillerde verimi düşürür. Toprak ekstraktı elektriksel geçirgenliğindeki (ECg) her 1,0 dS m'Hik artış, turunçgillerde yaklaşık % 13'lük verim düşüşlerine neden olmaktadır. Aşırı $Cl^- ve Na^+$ alınımı toksisiteye neden olur, ancak bu sorun uygun anaçların seçimi ile bir miktar azaltılabilir. Bu derlemenin amacı tuzluluğun turunçgiller üzerindeki etkileri ile ilgili kaynaklan özetlemektir. 1950'den günümüze kadar yayınlanan yaklaşık 80 literatür özetlenmiştir. Ayrıca sonuçların bir kısmı 3 tabloda da ortaya konulmuştur.

Tuzluluğun turunçgillere etkisi

Citrus is a salt sensitive crop. Salinity significantly limits citrus production in many areas worldwide. Saline irrigation water reduces the yields of citrus. Fruit yields decrease about 13 % for each 1.0 dS $m^{-1}$ increase in electrical conductivity of the saturated-soil extract (ECe) once soil salinity exceeds a threshold (ECg) of 1.4 dS m'K Accumulation of excess $Cl^-and Na^+$ can cause specific ion toxicities but this problem can be minimized by selecting rootstocks. The objective of this study is summarized the recent literature with regard to respond of citrus to salinity. About eighty papers were reviewed from 1950 to-date. Results of the literature review were summarized in three tables.
