| description | Identifying naturally existing abiotic-stress tolerant accessions in cereal crops
is central to understanding plant responses towards stress. Salinity is an
abiotic stressor that limits crop yields. Salt stress triggers major physiological
changes in plants, but individual plants may perform differently under
salt stress. In the present study, 112 barley accessions were grown under
controlled salt stress conditions (1 Sm−1
salinity) until harvest. The accessions
were then analyzed for set of agronomic and physiological traits. Under
salt stress, less than 5 % of the assessed accessions (CIHO6969, PI63926,
PI295960, and PI531867) displayed early flowering. Only two (< 2 %)
of the accessions (PI327671 and PI383011) attained higher fresh and dry
weight, and a better yield under salt stress. Higher K+/Na+ ratios were
maintained by four accessions PI531999, PI356780, PI452343, and PI532041.
These top-performing accessions constitute naturally existing variants within
barley’s gene pool that will be instrumental to deepen our understanding of
abiotic-stress tolerance in crops. |
