Investigation on Germination of Sage Brush (Artemisia aucheri)

This research was carried out to investigate germination in Artemisia aucheri. For this purpose, seeds were collected from Vard Avard/ Karaj in late November 2002. Experiments were performed in a 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 was found that it increased 10-17% when seeds were kept for six months from collection in fridge temperature conditions.
