Abstract
Pots experiment was conducted at AL-Hindiya Barrage (30 Km North West of Hillah City) during the period of Dec.1st,2015 till April,4th,2016.The aim of the study was to assess the effect of the cultivar and the salinity in traduced at different growth periods and their interaction on some morphological traits of root growth. Factorial experiment within C.R.D was adopted .The first factor represented four cultivars i.e Al-Hussein,Al-Rsheed,Fateh,IPA-99. The second factor represented six salinity treatments at 10.3 ds/m; continuous salinity , salinity at seed swing , salinity at tillering , salinity at boosting and salinity at flowering, in addition to the control treatment i.e . irrigation with the tap water . Seeds of wheat cultivars were sown in Dec.1st,2015 in 5 Kgs soil capacity , thinned to 5 seedling one month later. Samples were taken 10 days after flowering completion (i.e.April,4th,2016) in order to determine som morphological traits of root system that are, length ,size ,diameter and dry weight. Results revealed that ,apart from root diameter-Al-Hussein gave the highest values of studied characteristic . On the other hand ,the cultivar IPA-99 gave the lowest value , whereas, Al-Rasheed cultivar was in between. Concerning the Salinity , plants of continuous salinity showed the lowest values for the above mentioned characters. It is worth mentioning that , most characters negatively influenced by salinity were accompanied the continuous salinity treatment followed by tillering and flowering stages . On the other hand , the control treatment gave the highest values of studied character is tics . The interaction between the two factors significantly affected the above mentioned character is tics.
