Artemisia intramongolica is a kind of dominant shrub on sandy land in the typical grassland area of our country.It has been suitable to the hot and xeric habitat on sandy land for a long time and has formed a series of characteristics that are adaptive to its habitat.Different temperatures and treatments were designed to investigate the germination characteristics of Artemisia intramongolica seeds.It was found that optimal temperature for germination was 15 ℃ and 25 ℃.At 10 ℃ and 30 ℃

germination reached a low percentage and at 35 ℃

germination was inhibited.To test the tolerance to temperature and drought

seeds were subjected to pre-sowing treatment.Experimental data illustrate that germination of seeds can not be improved by pre-sowing treatment but can be greatly improved by pre-sowing treatment if the germination is under an optimal temperature.
