Effect of seed priming with salicylic acid and methyl jasmonate on germination and primary root length of cowpea genotypes

Abstract

The study was carried out to assess the optimum incubation time for cowpea seed priming and to determine the optimum concentration of salicylic acid (SA) and methyl jasmonate (MJ) for cowpea seed priming. We have observed that the optimum time for cowpea seed priming with methyl jasmonate is 6 hrs. Furthermore, we have analysed the effects of different concentrations of SA and MJ on germination percentage and root length of cowpea genotypes. We saw that SA decreased the number of seeds that sprouted, while MJ decreased the length of the first roots.
