Title:: Effect of Salt Stress on Germination Characteristics of Seed of Impatiens balsamina

Keywords:: Impatiens balsamina L.; salt stress; germination characteristics

Abstract:: The effects of salt stress on germination characteristics of seed of Impatiens balsamina were studied using six different salt concent rations，0%，0.2%，0.4%，0.6%，0.8%，1.0% of NaCl，Na₂CO₃ and NaHCO₃ under incubator.Seed germination delay，germination percentage，germination energy，root and seedling growth rate were measured.The results indicated that the germination characteristics and root and seedling growth were significantly affected by salt stress.The germination percentage and growth rate were significantly rest rained by Na₂CO₃ stress,while the NaCl stress was minimum.The effect of NaHCO₃ stress was at midway between Na₂CO₃ and NaCl.The order of salt stress impact from strong to weak on seed germination of Impatiens balsamina of seed were Na₂CO₃,NaHCO₃,NaCl.
