By using Solidago Virgaurea Complex which widely distributed from basal to alpine zones, some morphological and ecological characteristics and peroxidase isozyme variation were investigated along an altitudinal gradient. In the case of the mature plants in the field, some altitudinal differences in morphological and ecological characteristics were clear between zones below and above 2000 or 2200m alt., and the number of main peroxidase isozymes was increased till 2200m alt. with the increase of their habitat altitude, but decreased at 2370m alt.. In this progress, the appearances of some isozymes were changed among altitudinal different plant populations such as absence, rare presence (minors), or mostly presence (mains) in the plants. When the seedlings which were derived from the seeds collected at different altitudes were grown under controlled conditions, the mobility of main isozymes was larger in the seedlings from high altitudes than in these from low ones. The variation in the number and the mobility of main isozymes with the increase of habitat altitude seems to correspond to altitudinal speciation from S. Virgaurea ssp. asiatica to ssp. leiocarpa.
