Priming the seeds of fodder beet and also spraying the resultant plants with 1mM salicylic acid (SA) can considerably mitigate the harmful effects of salinity under controlled and field conditions.
Salicylic acid is an excellent plant hormone, which could be used to mitigate the harmful effect of salinity. I have used this plant hormone both in vitro and on intact plants, with excellent results. you could also use the amino acid proline, as well as silicon and selenium to mitigate adverse effects of salinity.
