- Abstract:
- ?In order to understand the effects of different types of salt and alkaline stress on growth traits and yield of soybean,two salt-alkaline-tolerant and two salt-alkaline-sensitive soybean cultivars were taken as experimental materials.The changes in organ biomass,pods number,seeds number,plant height,stem diameter and number of trifoliolate leaves per plant and yield under different types of salt-alkaline stress were studied.Results showed that organ biomass,pods number,seeds number,growth traits and yield of salt-alkaline-tolerant cultivars were significantly higher than those of salt-alkaline-sensitive ones.Under salt and alkaline stress,leaves and pods harmed more severe than stems.It also found that the yield was declined in salt and alkaline stress mainly duing to reducing grain number per pod,instead of reducing pod number.Under alkaline stress,the decrease percentage in all index were higher than salt stress and mixture-salt-alkaline stress.It suggested that the damage of alkaline stress lied in the effect of osmotic stress and ion toxicity on plant,as well as higher pH.
