Preliminary field trial results suggest barley over-expressing AVP1 has greater shoot biomass and grain yield in a saline field than barley plants without AVP1.. The aim of the project was to evaluate the shoot growth and grain yield of barley over-expressing AVP1 in a saline field to test whether or not this gene is able to improve the salinity tolerance of this cereal crop... Preliminary results suggest that the over-expression of AVP1 improves the growth of barley leading to an increase in shoot biomass and grain yield in a saline field...

The report proposes the idea that saline water, defined as having an electrical conductivity greater than 1.5 deciSiemens per metre (dS/m) (960 parts per million), has a part to play in filling the void of future losses of surface water... The aim of the report is to investigate if saline water can be successfully used without desalination, and what practices are required to reduce the effects of it on the crops and catchments they are applied to... Drip irrigation systems were by far the most common irrigation system using saline water...

Salt-tolerant plants possess the ability to either tolerate high levels of sodium or to exclude sodium from their system... Modern bread wheat is naturally more salt tolerant than durum wheat because it has a gene that helps exclude sodium from the xylem system, which stops it from reaching the leaves... The absence of the gene in durum wheat means it takes up about five times more sodium than its bread wheat cousins...

Soil salinity refers to a high concentration of salts in the landscape, mainly common salt or sodium chloride (NaCl), which has a negative impact on soil and water quality... A related protein in the test plant Arabidopsis, AtNHX1, has a very well-characterised role in salt tolerance... A deeper understanding of the mechanisms underlying this salt tolerance will be critical to the use of NHX proteins in producing transgenic salt-tolerant crop species...

The rationale for the project was an increasing awareness that subsoil salinity is an underlying constraint to cereal production in many regions of southern Australia... Growers will have access to salt-tolerant cultivars of wheat and barley that will enable them to make more informed choices to improve the productivity and reliability of crop yields in salt-affected land... The three general mechanisms of salt tolerance in wheat and barley are the exclusion of salt, the tolerance of high internal salt concentrations in leaves ("tissue tolerance") and the tolerance of high external salt concentrations in the soil ("osmotic stress tolerance")...

Results from the work showed that yields on the sodic soil at the MEF were correlated with yields on the saline soil at Ballidu... The work of Setter and Waters, and our confirmation of the themes of their work, show that all cereals have innate variation in their salt tolerance/sensitivity, and this variation needs to be better understood so that these plants can be located into the most appropriate landscapes, achieving better immediate results for growers... Results from the project suggest that cereal yields on millions of hectares of sodic land across southern Australia are affected by subsoil salinity...

Saline soils contain high concentrations of NaCl... The research will initially concentrate on improving the salinity tolerance of the major cereal crops wheat and barley, but will identify information that will be useful in improving salinity tolerance of other crops... Recent advances in genetic fingerprinting, plant phenotyping and allele characterisation provide a new opportunity to improve the salt tolerance of Australian cereal germplasm...
