چکیده
Haloxylon aphyllum is one of the most important species in sandy and saline areas in deserts, and some
ecophysiology characters for viability in unfavorable condition have evaluated in this species. Seed germination
is the critical stages in life cycle for species survival. In this study investigated salinity and temperature stresses
on percentage and velocity of germination using six salinity treatments (0, 100, 200, 300, 400 and 500 mM/I
NaCI) under four different temperature regimes (20:10, 30:10, 25:15 and 35:25 DC). The results showed that
seeds could germinate at very high salt concentration (500mM). However, highest germination percentage was
obtained in distilled water and thermoperiod 20:1cfc. Increased on salinity and temperature caused decreased
of percentage and velocity of germination. Seed germinated rapidly and no significant change in germination
was noticed after 10d. Recovery of seed germination investigated when seeds were transferred to distilled
water. The results indicated that recovery percentage was high in seeds were transferred from very saline
treatment with Lower temperature.
