Investigation on Germination of Sage Brush

This research was carried out to investigate germination in Artemisia aucheri . For this purpose, see s
were collected from Vard Avard / Karaj in late November 2002. Experiments were performed in
randomized complete design in the seed laboratory, Natural Resources Faculty, Tehran University.
Percent germination of seeds collected from three different altitudes were compared in dark as well as
in light conditions and at two different times. Results indicated that percentage of germination at both
times (December and next late May) at 2200m above see level was higher than those at 1800 and
2400m. Also, in light conditions it was higher than in dark conditions, but germination speed in dark
conditions was higher. Comparing the percentage germination at two different time stages, it w s
found that it increased 10-17% when seeds were kept for six months from collection in fridge
temperature conditions.
