Production, dispersal and dormancy of seeds of Albizia procera (Roxb.) Benth., a woody weed of pastures in Puerto Rico.
Several biological properties of Albizia procera, a woody weed of pastures in Puerto Rico are described. This species is reproductively mature after approximately three years and medium-sized trees growing in the open can produce 3500 pods in one year. Most of the pods and seeds fall within the extent of the crown. The first 6 cm of soil under a 15-year-old Puerto Rican A. procera stand had a seed bank of 315 seeds/m2. Seeds experimentally buried at 2.5 cm under the surface decayed at an exponential rate of 0.33 seeds/year with a half-life of 2.1 years. This study discusses implications of these biological properties for pasture management.
