Effect of Soil Salinity on Some Physical and Chemical Chracters of Mandarin Fruits Cultivar "Mahali "

Abstract

This study was conducted on 18 years old Mandarin trees (Citrus Reticulata Blanco.)Budded on Sour orange(Citrus aurantium L.) seedling rootstock grown under Date-Palm trees in an orchard at Baquba city-Diyala Province to determined the effect of soil salinity level on some physical and chemical characters of Mandarin fruits .Trees were selected from three locations having adifferent soil salinity levels(1.67,3.11,6.42 ds/m) .Results analized by using Randomize complete Block Dsign (RCBD),and sigi--ficancy degree were determined by less significanceDegree test (LSD).Study showed that increasing soil salinity Resulted in asignificant decrease in fruits mean weight,juice mean weight /fruit,but the juice percentage per fruit difference was not so.Soil Salinity increase caused asignificant increase in fruits total soluble solids. Fruits acidity Percentage differ significantly between fruits collected from the second and the third location on one hand and fruits of the first location on the other hand .
