Effect of water stress during anthesis on wheat seed viability

Research showed that vigor, viability, and quality of the plant seeds are affected by water availability during maternal plants growth. In order to investigate the effects of water stress during anthesis on wheat seed viability a pot experiment was conducted based on RCB statistical design with 5 treatments (control, non-irrigated for 10, 20 and 30 days after anthesis then re-irrigated and nonirrigated for all growth period) in 3 replications. Results showed that not irrigation for 10 days had no significant effect on seed viability. Seed viability was declined significantly by increasing water deficit intensity. Moreover, the maximum decline was obtained in the longest period of water stress along with 30 days of nonirrigated treatment. In this case, re-irrigation had no effective impact on viability loss
