Résumé
La morphologie racinaire de Bixa orellana L. est typique au systeme
radiculaire des dicotyledons caracterise par une racine principale portant
plusieurs racines laterales. L'effet de la composition minerale du sol
recolte dans six etats du Nigeria, sur la production des racines de Bixa
orellana a fait l'objet d'une etude. On a observe que le sol ayant une
plus grande fertilite avait aussi un rendement en poids de matiere seche
plus eleve et une plus grande production des racines. Les teneurs en azote
dans la zone racinaire influencait la production des racines plus que
celles de potassium et de phosphore. Cependant, N, K et P n'ont presente
aucune influence sur l'elongation de la racine principale.

Studies on the root systems of Bixa orellana
Macdonald, I.
Abstract
The root morphology of Bixa orellana L. is typical of a dicot root
system with a central tap root holding several laterals. The effect of
nutrient status of soil, collected from six states of Nigeria, on Bixa
orellana root production was studied. It was observed that soil with
higher fertility had higher dry weight matter yield and greater production
of roots. Nitrogen levels in the rooting medium influenced root production
more than did K and P. However, N, K and P had no influence on the
elongation of the tap root.
