Notes:
Absorption by the tap-root and by different nodal roots of white clover S100 and translocation of 32P were investigated to find to what extent nodal roots can compensate for the absence of a tap-root. 32P absorbed from the tap-root was distributed evenly within the whole plant. When translocation from the 2nd and 7th nodal roots was studied, similar distribution was obtained only from the nodal root closer to the centre of the plant. The backward movement of 32P absorbed from nodal roots at the base of the plant increased as the root size increased. Removal of tap-roots resulted in temporary depression of translocation; its effect disappeared within 3 weeks.It is concluded that the ability of nodal roots to compensate for loss of the tap-root depends on their position and size.
