Abstract

Investigations on the utilization of the generative storage potential of indeterminated field bean genotypes (Vicia faba L.) The gradation in seed yield between and within the inflorescences of a field bean plant results from a hierarchical control by way of internal competition in connection with hormonal regulation. Following this hypothesis in genotypes with different yielding capacity (2 inbred lines, 1 hybrid) the two proximal flowers/inflorescence of the nodes 3–6 (counted from the bottom of the plant) were either removed or treated with growth regulators. AMO‐1618 was applied for inhibition of the gibberellic acid biosynthesis, or chlorflurenolmethylester (CFM) for reduction of indole‐3yl acetic acid translocation as both phytohormones might be concerned with the hierarchical control of the storage system. — Independent from yield level a reduction of the used storage potential in control plants up to 50% by treatments was fully compensated for in other regions and positions of the plant. AMO‐1618 application in some cases indicated an increased seed yield/plant, whereas CFM only increased the number of sterile pods/plant. These effects are discussed in relation to the storing efficiency and to yield stability of an indeterminated faba bean plant.
