Abstract

Water deficit stress is one of the most important environmental stress factors that affect all crop physiological and biochemical processes. In this study, putrescine (Put) foliar application (0, 75 and 150 ppm) was investigated on physiologic and morphologic characteristics of wheat (Tiriticum aestivum var sw-82-9) under different levels of water stress as complete randomized experiment in 12 treatment and 3 replication. All experimental traits affected significantly by withholding in irrigation at different growth stages. The grain yield was decreased as result of withholding in irrigation at stem elongation, flowering and seed filling period stages. Withholding in irrigation in different growth stages decreased number of grains per spike, thousand grain weight, total chlorophyll contents and relative water content, whereas increased grain protein, proline content, and electrical conductivity of leaf. Putrescine foliar application specially 150 ppm concentration prevented degradation

Keywords

Putrescine, Wheat, Physiologic characteristics, Water deficit Stress

Conclusion

Putrescine foliar application significantly increased grain yield, protein percent, HI, and E.C of wheat leaf under water deficit stress which could be applicable in prevention of economic losses and refinement of crop productivity
