Abstract

Greenhouse experiments were conducted to assess the effects of soil salinity on emergence, growth, water status, proline content and mineral accumulation of seedlings of Suaeda nudiflora (Wild.) Moq. (Chenopodiaceae). NaCl was added to the soil and salinity was maintained at 0.3, 3.9, 6.0, 7.9, 10.0, 12.1 and 13.9 dSm-1. This bush species is salt tolerant at seed germination stage. Growth of plants was stimulated by salt and their optimum growth was at 7.9 dSm-1 salinity. Increase in plant growth was due to osmotic adjustment and increased leaf area. Results suggested that S. nudiflora is a halophytic plant. The K and Na profiles of this plant suggested its two distinct traits: (i) high Na+ influx and/or low Na+ efflux on root plasma membrane and (ii) high K+/Na+ discrimination. Changes in tissues and whole-plant accumulation patterns of other nutrients, as well as possible mechanisms for avoidance of Na toxicity in this species in response to salinity, are discussed.
