Abstract
Stem apex and flower removal treatments were applied to six morphologically very different genotypes. Two independent sets of characters were observed on the plants: a flower abcission character (YP/F) and a pod nutrition character (P/YP, S/P, W).
Top removal reduced flower abcission but resulted in poor pod nutrition. Flower removal also reduced flower abcission but improved pod nutrition. Yield was decreased and protein content increased by the treatments in comparison with the control. Genotype x treatment interaction concerned more the magnitude of response than the type of response to treatment. The results identified within-plant competition between organs including:
-
between the top of the plant and young pod formation.
-
between flowers on a node destined to become young pods,
-
between pods in their relation to the leaf area, as a source of nutrients.
The significance of this within plant competition is discussed.
