Qatar has a dry, subtropical desert climate, with minimum annual rainfall and intensely hot and humid summers.
Using indigenous grass, those adapted to local conditions have the potential to be used for fodder and can also be used for restoration or rehabilitation of degraded rangelands.
Chloris virgata, Coelachyrum brevifolium and Cenchrus ciliaris bloom twice a year from April to May (summer) and September to October (winter) under the nursery condition.
Therefore, it is important to understand, how seeds produced in different seasons affect the dormancy as well as germination of these species.
Seeds of C.
virgata, C.
brevifolium and C.
ciliaris, three desert grasses, were collected from the plants growing on Shahniya nursery in two different seasons, summer (May) and winter (October).
The seeds collected in May (summer) were stored up to winter.
However seeds collected in October (winter) were immediately used for experiment.
We compared the germination potential of seeds that matured in different season at different alternating temperatures at 15/25, 20/30 and 25/35 C.
Lower temperatures correspond to the dark period, while higher temperatures reflect the light period.
Seeds collected in summer season (old seeds) were heavier as compared to seeds collected in winter season (new seeds).
Winter seeds of C.
virgata seem to be dormant, while summer seeds, germinated well in all the tested temperature regimes.
However, C.
ciliaris seeds showed opposite trends.
