| 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 on the yield parameters of four wheat cultivars. The yield Paramet- -erswere spikes number. plant-1, spike’s length, spikes weight, spikelet number. spike-1, grain number . spike-1 , grain yield . plant-1 and weight of 1000 grains. 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 significant on the previous mentioned traits,and proline at 20 mg . l-1 was more effective on all 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 was significantly effective on the studied parameters where cultivars treated with 20 mg .l-1 proline gave the highest values compared with the control treatment ( ie. 0 mg . l-1 ) , and the interaction between cultivars and the field capacity was also effective on the studiedparameters . Cultivars grown with 100% field capacity gave higher values of the studiedparameters .On the other hand , those cultivars grown with 25% field capacity gave the lowest values of the previous mentioned parameters , and the interaction between the proline and field capacity was also significant on the studied parameters . The proline at 20 mg .l-1 and 100% field capacity treatment gave the highest values of studied parameters , whereas plants grown with 0 mg .l-1 and 25% field capacity gave the lowest values of studiedparameters . The interaction between cultivars , proline and field capacity was also significantly effective . Cultivars grown with 20 mg .l-1 proline and 100% field capacity gave the highest values .On the other hand, those cultivars grown without proline application , and 25% field capacity gave the lowest values of the previous mentioned parameters . | ||
