Abstract:
In order to study of hydropriming and halopriming on germination and early growth stage of wheat (Triticum aestivum
L.) an experiment was carried out in laboratory of the Department of AgroNomy and Plant breeding, Shahrood University
of Technology. Seed treatments consisted of T1: control (untreated seeds), T2: soaking in distilled water for 18 h
(hydropriming). T3: soaking in -1.2 MPa solution of CaSO4 for 36 h (halopriming). Germination and early seedling
growth were studied using distilled water (control) and under osmotic potentials of -0.4, -0.8 and -1.2 MPa for NaCl and
polyethylene glycol (PEG 6000), respectively. Results showed that Hydroprimed seeds achieved maximum germination
seedling dry weight, especially during the higher osmotic potentials. Minimum germination was recorded at untreated
seeds (control) followed by halopriming. Under high osmotic potentials, hydroprimed seeds had higher GI (germination
index) as compared to haloprimed or untreated seeds. Interaction effect of seed treatment and osmotic potential
significantly affected the seedling vigour index (SVI).
Machine summary:
Results showed that Hydroprimed seeds achieved maximum germination seedling dry weight, especially during the higher osmotic potentials.
Interaction effect of seed treatment and osmotic potential significantly affected the seedling vigour index (SVI).
, 2006; Roy and srivastava, 2000) suggested that the adverse and depressive effects of salinity and water stress on germination can be alleviated by various seed priming treatments.
Although the effects of priming treatments on germination of some seed crops has been studied, but relatively little information is available on the invigorating of wheat seed under salt stress.
The aim of the study was to evaluate whether priming with water and salt solution (CaSO4) results in enhancement of seed vigour in wheat (cv.
Further to realize whether responsible factors for failure of wheat seed germination under saline condition is an osmotic blockade or is due to toxic effects of NaCl. 2.
First factor was solution (NaCl and PEG), the second factor was seed treatments (control, hydropriming and halopriming) and third was osmotic potential levels (0, -0.
