Abstract:
Grafted rose plantlets were grown in a controlled growth room in order to study the effect of Ca and B concentration on Ca uptake, distribution and transport to the apex. There were three Ca levels and three B levels. Root development was affected by Ca and B levels available to the roots. 45Ca taken up was readily translocated to the scion, but accumulated in the rootstock in low-Ca plants. Translocation of Ca was increased by increasing B concentration. The relative Ca sink strength of low- and high-transpiring organs was affected by Ca and B concentrations. Increasing Ca level will increase rose growth only if B concentration is adjusted accordingly. © 1993 Kluwer Academic Publishers.
