The endemic variety Glycine max (L.) Merr. cv. Namdan is one of the most important crops in the agricultural production in Nghe An province (Vietnam). Experiments were carried out to assess the adaptive capability of that soybean variety in drought condition. The oxidative stress with a burst of O2.- and H2O2 in soybean leaves resulted the obviously cellular membrane damage that was illustrated by a continuous increase in content of products of lipid peroxidation. A high accumulation in activity of enzymatic antioxidants such as SOD, CAT and POX would detoxify the excess of O2.- and H2O2 and decrease oxidative damages. An increase in amino acid proline’s content protects the stressed cells by adjusting intercellular osmotic potential. Those results suggested the drought tolerant capability for variety Namdan.
