Abstract
Pot experiment was conducted in a private field located on the main road of Kerbala – Babylon , 10 kms eastern of Kerbala during the season of 2010 - 2011 . The aim of this study was to assess the effect of water stress and proline concentration on the the growth and the proline concentration in the flag leaf of four wheat cultivars . Factorial experiment within completely randomized design with four replicates was applied . The experiment included four wheat cultivars ( ie. Fateh , Adnania , IPA 99 and Sham 6 ) , three concentrations of proline ( ie. 0 , 20 and 40 ) mg . l-1 and three levels of field capacity ( i.e. 25 , 50 and 100% ) . The results could be summarized as follow : The effect of cultivars was not significant on the shoot/root ratio, on the other hand , cultivars significantly affected proline concentration . Proline at 20 mg . l-1 was more effective on studied parameters compared with other concentrations ( ie. 0 and 40 ) mg . l-1 , and, the field capacity of 100% was the best compared with 25% and 50% field capacities . The interaction between cultivars and the proline concentrations was not significant on the shoot/root ratio, on the other hand , it was significantly effective on the proline concentration . The interaction between cultivars and the field capacity was also effective on the studied parameters , the interaction between the proline and field capacity was also significant on the studied parameters. No significant effect was found due to the interaction between studied parameters on the root/shoot ratio , whereas , they had a significant effect on the proline concentration .
