Özet: Salinity is major obstacle in crop production throughout the globe. It retards plant growth and brings drastic losses in yield. Therefore, a pot experiment was executed at the research area of University of Agriculture Faisalabad to evaluate the influences caused by salinity stress on maize. Different levels of NaCl (Control, 4 dSm-1, 8 dSm-1, 12 dSm-1and 16 dSm-1) were used as treatments. Maize hybrid KS-85 was sown as trial crop and complete randomized design was used to allocate the treatments. Data for different parameters were recorded and analyzed statistically at 5% probability level which showed that plant germination and growth were reduced at higher salinity, while, proline contents exhibited the opposite trend. At salinity level 16 dSm-1, the plumule and radical length was decreased by 89.86% and 92.65% respectively when these were in comparison to those from control. Plumule fresh was decreased by 86.79%, while, the fresh weight of radical was decreased by 84.61%. Similarly, shoot and root length was reduced by 54.28% and 59.72% respectively. The proline content was increased up to 369.23% as compared to control while at 16dSm-1. In conclusion, maize is a moderately salt tolerant crop, but at higher salinity, growth of maize was impaired and proline contents were boosted up.
