Abstract

Twenty genotypes of moong (Vigna radiata) were germinated at three conductivity levels viz. 6, 9 and 1.2 mmhos/cm with distilled water to serve as control in Petri dishes with filter paper. The seedlings were sampled after 72 hours of sowing. Root elongation varied with the level of salinity and genotype. Increased root elongation was observed at one or the other level of salinity used in most of the genotypes studied, Hypocotyl elongation on the other hand, was consistently reduced with increasing levels of salinity in most genotypes. However, in certain genotypes, the additive effect of salinity in reducing hypocotyl elongation was not observed. Fresh and dry weights of the embryo axis were reduced by salinity, however, increasing salt concentrations did not always reduce fresh and dry weights in all the genotypes.
