This study aimed to improve cowpea seed germination and seedling growth by using some antioxidant compounds naturally produced or up taken by plants. The effect of soaking cowpea (Vigna unguiculata) for 2 h in aerated solution of different antioxidants; ascorbic acid (AsA) and gallic acid (GA), each at 0.0, 50, 100, 150, 200, 250 and 300 ppm, sodium selenate (NaSeO4) and nanoselenium (SeNPs ≈ 33.4 nm) chemically prepared, each at 0.0, 6.25, 12.5, 25, 50 and 100 μM on seedling length and activities of some hydrolytic enzymes were tested. Seeds of treated and untreated cowpea were germinated at 25°C ± 0.5 under dark controlled conditions for 4 days. Results showed that AsA, GA, NaSeO4 and SeNPs at low concentrations significantly improved p... view more»
