When soybean, Glycine max (L.) Merr., plants are exposed to harmful levels of salt in the soil, they can respond by decreasing rates of water loss through their leaves. This results in increased leaf surface temperatures, due to a decrease in evaporative cooling. Because accumulation of chloride (Cl-) in Arkansas soils continues to impact soybean production, we set out to test whether non-destructive measurement of leaf temperature could visualize differences among cultivars with varying levels of tolerance to salt. Infrared reflection from leaves demonstrated differences between a Cl--includer and Cl--excluder treated with high levels of salt. The differences occur well before visible changes such as curling and browning in leaves. [ABSTRACT FROM AUTHOR] |
