Abstract
This study carried out in Chaleki Research Station in Gorgan in 2000. Station altitude and annual rainfall are 85 m and 600 mm respectively.
Seedlings of Hypericum perforatum collected from different locals are varied in aspect of leaf size and height. Two locals were DRAZNO in west and GARMAB-DASHT in east of Gorgan with 2000 m and 400 m altitude respectively.
Seedlings were Planted with intervals 30cm on row and 50 cm between row in autumn. The top yield of plants was harvested from 10 cm of terminal after 30% flowering and then were dried at room condition. Dry matter of tops, flowering date, Plants height and tillering was recorded from 10 random plants. The yield of the tops of plants in DRAZNO and GARMAB-DASHT were 6758 and 1696 Kg/ha respectively that was significant in T- Test(0.01, t=5.19). The till number in both local was almost equal but the plant height in GARMAB-DASHT (120.3 cm) was more than DRAZNO (67.7cm). The correlation between the tops of yield and tillering was for GARMAB-DASHT 0.70 and for DRAZNO 0.93.
