Chin. J. Ap p l. col .,2005, 16(8) : 1432~ 1436. The study on the growth characters,above and underground biomass,and rootshoot ratio of Pogonatherum p an iceum grown on three types of substrates and five types of habitats in Chongqing showed that there w ere signifi cant differences in plant growth characters, including stalk basal diameter,plant canopy and height, root system area and depth, and maximum root length among five habitats. For shoot growth, though the plants grown on 2 purple soil had the maximum stalk basal diameter ( 15. 18 cm) ,canopy (3 086. 77 cm ) and height ( 6. 58 cm) while those grown on purple sandy rock had the minimum values ( stalk basal diameter 10.
