Dcj. Wessels et Mj. Potgieter, OBSERVATIONS ON THE NATURAL GRAFTING OF BOSCIA-ALBITRUNCA ONTO COLOPHOSPERMUM-MOPANE AND COMBRETUM-IMBERBE, South African journal of botany, 63(5), 1997, pp. 299-300
Natural grafting of Boscia albitrunca onto Colophospermum mopane and C
ombretum imberbe is reported for the first time. Scions of Boscia albi
trunca, without independent rootstocks, were found at different height
s on the main trunk and lateral branches of C. mopane and C. imberbe s
tock, indicating no preferential point of establishment. Speculations
about possible advantages of such a heterograft are made. An opinion i
s expressed about the physiological interactions between these heterog
rafts.
