Abstract:In order to explore the salt distribution patterns in different organs and the characteristic of salt secreted from leaves of Glycyrrhiza uralensis, we cultured G. uralensis seedlings with a complete Hoagland nutrient solution containing 0, 80, 160 and 320 mmol·L-1 NaCl for 21 days. The contents of K+, Ca2+ and Na+ secreted from the leaves were measured by ICPAES; In addition, twoyearold G. uralensis grew in heavy salinealkali soil were collected, the contents of K+, Na+, Ga2+ and Mg2+ in different organs (roots, rhizomes, stems, old leaves and young leaves) of G. uralensis were measured by ICPAES. The aim for this study is to provide reference for salt tolerance theory of G. uralensis by comparing the salt accumulation characteristics with salt secretion characteristics. The results were shown that: (1) more salt ions secreted from leaves of G. uralensis with the increased concentration of NaCl, and the secretive content of Na+ was much greater than that of Ca2+ and K+. (2) The order of accumulation of K+ among the different organs was young leaves > roots > rhizomes > stems > old leaves; Na+ accumulation in every organ is very limited and have no significant difference among them; The order of Ca2+ accumulation among the different organs was old leaves > young leaves > stems > rhizomes > roots; All in all, in high salt habitats, the young leaves is the main organ to accumulate K+, the old leaves is the main organ to accumulate Ca2+. It is a obvious characteristic that G. uralensis reject accumulating Na+, the content of Na+ in every organ of G. uralensis is very low; Na+ is the main salt ion secreted from leaves; G. uralensis can avoid accumulating excessive Na+ in the plant by excluding Na+, which is the main reason that G. uralensis can grow in high salt habitats.
