- Intervention effect Decapitation and removal of unfolding leaves increased growth of remaining sugar-beet leaves, especially at less advanced stages.
- Intervention effect Remaining leaf area increased two to threefold.
- Intervention effect Remaining leaf weight increased five to sixfold.
- Intervention effect Both shoot treatments transiently increased root growth rate, with longer promotion at later growth stages.
- Mechanism The authors attributed growth promotion mainly to changed substrate availability and distribution after shoot growth was retarded and the shoot apex removed.
- Intervention effect Partial shoot removal caused proportionately greater growth of the remaining shoot.
- Intervention effect Partial root removal affected shoot growth only when the root was reduced to one quarter.
- Intervention effect Removing more than half the root did not induce compensatory growth of remaining root.
- Intervention effect Removing more than one third of the root decreased net assimilation rate.
- Intervention effect Partial shoot removal increased net assimilation rate in plants with the same root sink strength.
