Influence of Selenium on Growth, Physiology, and Antioxidant Responses in Maize Varies in a Dose-Dependent Manner

Table 3

Effect of different selenium levels on transpiration rate, stomatal conductance, photosynthetic rate, chlorophyll contents, relative water contents (%), and membrane stability index.

Each value is an average of three replications ± SE. Various letters (a–d) showed that the significant difference between treatments was determined by the LSD test ().
