Abstract

Greenhouse experiments were conducted to assess the effects of soil salinity on germination, growth, water status, proline content and mineral accumulation of seedlings of Aegiceras corniculatum (L.) Blanco (Myrsinaceae). NaCl was added to the soil and salinity was maintained at 0.3, 3.9, 7.9, 12.1, 16.1, 19.7, 24.0, 28.0, 32.0, 36.0 and 40.0 dSm-1. This plant is highly salt tolerant at germination stage. Growth of seedlings was significantly promoted by low salinity and their optimum growth was obtained at 24.0 dSm-1. Moreover, higher salinities inhibited plant growth. Water potential of tissues became significantly more negative with increase in salinity. Proline content in tissues significantly increased as salinity increased. Concentration of Na in tissues significantly increased, whereas K, Ca, N and P content decreased with increase in salinity. Changes in tissues and whole-plant accumulation patterns of other nutrients, as well as possible mechanisms for avoidance of Na toxicity in this plant in response to salinity, are discussed.
