What is the salt tolerance of wheat?
What is the salt tolerance of wheat?
Wheat (Triticum aestivum) is a moderately salt-tolerant crop (Maas and Hoffman, 1977). In the field, where the salinity rises to 100 mM NaCl (about 10 dS m−1), rice (Oryza sativa) will die before maturity, while wheat will produce a reduced yield.
What is the mechanism of the salt tolerance?
Plant growth responds to salinity in two phases: a rapid, osmotic phase that inhibits growth of young leaves, and a slower, ionic phase that accelerates senescence of mature leaves.
What is a tolerance to salinity?
The salt tolerance of a plant is often defined as the degree to which the plant can withstand, without significant adverse effects, moderate or high concentrations of salt in water on its leaves or in the soil within reach of its roots. In practice, salt tolerance is a relative term.
Why is salt tolerance important?
Salt stress inhibits photosynthesis by reducing water potential. So the main aim of salt tolerance is to increase water use efficiency under salinity.
Which gene is used for development of salt tolerant crops?
The glycophytic NHX gene from A. thaliana was widely explored for developing salt tolerance in many crops including tomato, brassica, maize, wheat, etc.
What is the most salt-tolerant crop?
Salt tolerance of cereal crops Most of the major cereal crops exhibit high tolerance to soil salinity. In this group are sorghum, wheat, triticale, ripe, oats and barley. Only exceptions are corn and rice.
Which are salt-tolerant crops?
Leaf damage
| Sensitivity | Chloride (mg/l) | Affected crop |
|---|---|---|
| Sensitive | <178 | Almond, apricot, citrus, plum |
| Moderately Sensitive | 178–355 | Capsicum, grape, potato, tomato |
| Moderately tolerant | 355–710 | Barley, cucumber, sweetcorn |
| Tolerant | >710 | Cauliflower, cotton, safflower, sesame, sorghum, sunflower |
What crops are salt tolerant?
“The most salt-tolerant crops are barley, camelina, rye, safflower, sunflower, and sugar beets,” says Aberle.
Which crop is more tolerant to salinity?
Which is the most salt-tolerant crop?
“The most salt-tolerant crops are barley, camelina, rye, safflower, sunflower, and sugar beets,” says Aberle. “We’ve replaced a lot of these crops with the least-tolerant crops, which are dry beans, soybeans, corn, and field peas.”
