Abstract EN
Soil salinity affects a large and increasing amount of arable land worldwide, and genetic and agronomic solutions to increasing salt tolerance are urgently needed.
Experiments were conducted to improve wheat seed performance under salinity stress conditions after priming.
An experiment was conducted using a completely randomized design of four replications for germination indices in wheat (Triticum aestivum L.
cv.
Caxton).
Normal and primed seed with PEG6000 at -1 MPa and five concentrations of NaCl (0, 50, 100, 150, and 200 mM) were tested.
Results indicate that priming seed significantly (P<0.05) increased germination percentage at first count and final count, coefficient of velocity of germination, germination rate index, and mean germination time, while increasing of NaCl concentration significantly reduced it.
Priming seed improved germination attributes at all NaCl concentration levels.
The priming appeared to be able to overcome the effect of salt stress at 50 to 100 mM and reduce the effect of NaCl at higher concentrations up to 200 mM.
The primed seed gave both faster germination and led to higher germination when under salt stress.
We conclude that using priming techniques can effectively enhance the germination seed under saline condition.
