قابلية تحمل ستة أصناف من الحنطة لتراكيز مختلفة من كبريتات الكالسيوم في المحلول المغذي

Abstract

ِAn experiment was carried out during winter growing season 2003-2004 in the green house of the department of soil, State Board for Agricultural Research at Abu-ghraib. The objective was to study the tolerance ability of six wheat cultivars (Abu-graib , Al-fateh, Sham4, Sham6, telafar2 and Telafar3 ) to increasing concentrations of calcium sulphate (0,5,10 and 15) mmol/L using hydroponic technique. It was found that increasing concentration of calcium sulphate in the nutrient solution resulted in a clear decrease in all the studied characteristics, with clear difference due to the different tolerance of these varieties to high concentrations of calcium sulphate. Al-fateh cultivar was the best in term of tolerance as it is showed high values for the studied characteristics, while Sham6 showed explicit sensitivity and low tolerance ability to high concentration of calcium solphate due to lower values for most parameters. The tolerance ability for other cultivars was between Sham6 and Al-Fateh cultivars.
