Effect of different sowing densities, spacing and seed quality on the development of plants of Bombacopsis quinata in the nursery


, : Effect of different sowing densities, spacing and seed quality on the development of plants of Bombacopsis quinata in the nursery. Informe de Investigacion Monterrey Forestal Ltda ( 11): 7 pp.

In a nursery trial in Colombia, 3 transplant densities were compared, viz. 30, 42 and 60 seedlings per msuperscript 2, using seed from commercial plantations and from a clonal seed orchard. At 6 months, root-collar diameter ranged from 2 cm at a density of 30 plants/msuperscript 2 to 1.5 cm at 60 plants/msuperscript 2, the percentage of useful seedlings being 70% and 48%, respectively.
