NON- ENZYMATIC ANTIOXIDANT RESPONSES OF LOCAL AND IMPROVED DROGHT TOLERANT VARIETIES OF MAIZE (ZEA MAYS L.) TO WATER STRESS
Abstract
Maize (Zea mays L.) is a cereal crop with enormous agronomic and economic importance. However, the production of maize is severely affected by drought which limits its yield. Improvement in drought tolerant maize varieties with antioxidant capacity can have substantial impacts on maize productivity. This study evaluated the non-enzymatic antioxidant responses of four(4) local maize varieties (TZM 154, TZM 1389, TZM 1414, and TZM 1136) and an improved variety (SAMMAZ 45) Under varying water stress levels (T1=100%WFC, T2=50%WFC, and T3=25%WFC) at vegetative stage of growth. Total ascorbic acid, total flavonoids, and lipid peroxidation values were analyzed using standard methods. The results showed significant increase (p
