Abstract
In order to development medicinal Artemisia herbs of high quality, Korean A. annua L. were investigated with its ecological and morphological characteristics, and basic statistical data of agronomic characteristics. This species, which is annual herb, is mainly distributed to marginal land, riverside, roadside, grassland. Ecological niche is low species in competition of the others. Its pollination is basically anemogamous, but is frequency pollinated by insects. This species is characterized as tap root, 1~3 pinnate compound leaf of ovate or narrowly ovate, stem is green, erect and solitary. Inflorescence is paniculate, receptacle is not hair. Capitulum, consist of ray floret and disk floret, is subglobose shape. Additionally, this species could be easily discriminated from related Artemisia herbs by the capitulum size. Ray floret is female, disk floret is bisexual. Flowering season is from August to October. Seed is achene unattached hair. Stem length ranged from 179 cm to 225 cm, and stem diameter and number of branch were $17.14\;{\pm}\;1.68\;mm$, $2.43\;{\pm}\;0.51\;mm$, respectively. Length and width of leaf were $14.5\;{\pm}\;0.5\;cm$, $15.0\;{\pm}\;1.0\;cm$, and leaf number of main stem were $48.06\;{\pm}\;10.57\;cm$, respectively. Fresh weight of aerial parts and root were $364.7\;{\pm}\;14.1\;g$, $32.6\;{\pm}\;5.1\;g$, and its dry weight were $136.6\;{\pm}\;10.0\;g$, $14.9\;{\pm}\;2.34\;g$, respectively.
