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 w ere designed to investigate the germination characteristics of A r te mis i a intr among ol ica seeds. It w as found that optimal temperature for germination w as 5 and 25 . A t 0 and 30 , germination reached a low percentage and at 35 , germination w as inhibited. To test the toler
