Germination is regarded as sensitive stage in growth cycle, because of it major role in final
compression. However, it has been observed that plants show relative tolerance to drought and salinity
in different vegetative growth stages.In order to study the effects of drought and salinity stress on
germination and some characters of five thymus species (T. daenensis ،T. pubescens ،T. Kotschyanus,
T. fallaxandT. vulgaris), two factorial experiment was conducted in Completely Randomized Design
with three replications. Treatments for first experiment were six levels of drought potentials (0, -3, -6,
-9, -12 and -15 bar) and five species of thymus and Treatments for second experiment were six levels
of salinity salinity (0, 10, 20, 40, 80 and 160 mM) and five species of thymus. Measured traits were:
germination percentage, radicle length, plumule length, mean germination time, germination rate and
seed vigor index. According to the results it was revealed that effect of drought and salinity, species
and interaction were significant on all parameters. Species showed significant differences for all the
characteristics at germination under drought and salinity stress. In this research, T. fallaxand Th.
daenensisin the most measured factors were more tolerant than the others.
