Rates of Dry-matter Production in Some Tropical Forest-tree Seedlings

D. U. U. OKALI

Department of Botany, University of Ghana Legon

Received: 29 July 1970   

An analysis of growth in full daylight of four tropical forest-tree seedlings and Helianthus was made with the view of ascertaining whether woody plants in the tropics have a lower net assimilation rate than herbaceous plants as has been demonstrated in other environments. Significant differences in net assimilation rate were found between Helianthus and three of the woody species tested: Chlorophora excelsa, Musanga cecropioides, and Terminalia ivorensis; the fourth woody plant, Ceiba pentandra, had an unusually high net assimilation rate which, in one experiment, did not differ significantly from the value found for Helianthus.

The data are discussed in relation to the general problems of comparative growth-rates of herbaceous and woody plants and of factors contributing to differences in forest productivity between climates.
