VEGETATIVE PROPAGATION STUDIES IN KOLA (COLA SPP.) III POTENTIAL USE OF LEAF CUTTINGS FOR ROOTING

Abstract

Old and young leaves of Cola acumiriala (P. Beauv) Schott and EndIicher and three clones of C. nitida (Vent,) Schott and Endlicher (AA125, AA176 and AA231) were set in the propagator either as a whole leaf, lower half or upper hall leaf cutting. At the end of six months after setting, only the young leaves of C. acuminata rooted with the upper halves rooting better than either whole leaf or lower half leaf setting. The bases of the differential rooting ability between two species, as well as the magnitudes of rooting in C. acuminata leaf cutting position are discussed.
