Abstract

Seed germination and seedling performance of Dorke and Omankwa corn varieties were investigated under varying salinity, copper and zinc concentrations. Sample analyses were done using AAS. Germination of both seeds decreased with increasing Sodium chloride. When NaCl was increased from 3 to 6ppm, the range of germination of Dorke seeds reduced from 33 - 20% while that of Omankwa seeds reduced from 20% to 13.3%. 85.5% germination in 60mMNaCl was the highest in Dorke and 72.2% germination in 90mMNaCl was the lowest. 87.8% germination in 30mMNaCl was the highest for Omankwa hybrid, 30% in 90mM being its lowest. Cu2+ accumulated more in the roots than shoot of both hybrids, while Zn2+ accumulated more in their shoots than the roots. Highest mean fresh weight of Dorke was recorded in moderate Cu2+ and Zn2+. Also highest mean fresh weight of Omankwa hybrid occurred under low Cu2+ level and moderate Zn2+ levels, but was highest in higher levels of Zn2+ and Cu2+ mixture. From the study, farmers are advised against planting the two hybrids in alkaline soils and to apply Cu2+/Zn2+ based fertilizers to improve photosynthetic activity and biomass.
