Abstract
The influence of nickel on seed germination and early seedling growth of Hordeum vulgare L. grown in Petri plates was studied. The ultimate germination was 100% at all the nickel treatments. The germination speed was found maximum at 1 µM nickel concentration. Lower concentrations of nickel resulted in an enhancement while higher levels resulted decrease in shoot-root length, fresh weight, dry matter production and chlorophyll contents of seedlings. Soluble protein contents increased linearly with increasing application rates of nickel.
