Growth and Physiological Responses of Maize and Sorghum Genotypes to Salt Stress
Figure 4
Leaf gas exchange rates, transpiration (), stomatal conductance (), and net photosynthetic rate () of four maize genotypes (CUBA1, B73, B5C2, and BR1) when irrigated with nutrient solution at EC of 1.5 dS m−1 or saline solution at EC of 8.0 dS m−1 for 40 days. Means with the same letters on different days are not significantly different tested by Student-Newman-Keuls (SNK) multiple comparisons at . ***, **, *, and NS are significant at , 0.01, 0.05, or nonsignificant between the two treatments by -test. Vertical bars represent standard errors (replication of 4).
