The adverse effects of NaCl induced salt stress on growth attributes and endogenous levels of
gibberellins (GA), abscisic acid (ABA), jasmonic acid (JA) and salicylic acid (SA) soybean cv.
Hwangkeumkong was showed. Plant length, biomass, chlorophyll content, number of pods, 100
seed weight and yield significantly decreased in response 70 mM and 140 mM concentrations of
NaCl. Under salt stress, the endogenous GA and free SA content decreased, while a significant
increase in the endogenous ABA and JA contents were observed. The results showed that salinity
stress drastically reduce growth and yield components of soybean by affecting endogenous growth
hormones.
