Abstract:
In order to investigate
salinity stress on seed reserve utilization and
seedling growth of treated seeds of barley
(Hordeum vulgare L.), an experiment was
carried out. Factorial experiment was
carried out in completely randomized design
with three replicates. To create salinity
stress, NaCl in osmotic levels at 0 (as
control), -4, -8, -12 and -16 bar were used.
For seed priming, gibberellin (GA) 50 ppm
was used. Our results showed that treatment
× drought interaction on these traits:
germination percentage, weight of utilized
(mobilized) seed, seed reserve utilization
efficiency, seedling dry weight and seed
reserve depletion percentage were
significant. The highest germination
percentage, weight of utilized (mobilized)
seed, seed reserve utilization efficiency,
seedling dry weight and seed reserve
depletion percentage were attained from
priming by gibberellin at control conditions.
Thus, priming increased characteristics as
compared to the unprimed. Priming
improved seed reserve utilization such as:
weight of utilized (mobilized) seed reserve,
seed reserve depletion percentage, seed
reserve utilization efficiency and seedling
growth in barley under salinity stress.
