Abstract
Shoot and root dry weights of greenhouse-grown mycorrhizal and nonmycorrhizal Podocarpus macrophyllus were not different after 8 months. Shoot dry weights were not different for plants grown in the 2 pine bark: 1 moss peat: 1 sand (v/v/v) medium amended with Florida rock phosphate (14% P) at either 0.54, 1.08, 2.16, 4.32, or 8.64 mg P/cm 3 (14.5, 29, 58, 116, or 232 oz P/yd 3 , respectively) of medium (2300 cm 3 /container) or 0.27 mg P/cm 3 (7.25 oz P/yd 3 ) from superphosphate (9% P). Root dry weights for plants grown without a P amendment were greater than for plants grown with rock phosphate amendments of 0.54 and 1.08 mg P/cm 3 . Growing medium extract P levels 51 days after potting and thereafter were 2 ppm or less for the rock phosphate treatments, while P levels for the superphosphate-amended mediunl decreased from 169 ppm on day 51 to 9 ppm on day 236. Phosphorus accumulated by shoot and root tissues exhibited a similar relationship to shoot and root dry weights.
