Influence of anti-lodging plant growth regulators on root activity in barley-Wagga Wagga 2017

The aim of this experiment was to investigate the effect of two commonly used PGRs on root growth. It was hypothesised that if root growth modification occurred due to PGR application it would be a result of either the PGR altering the allometric balance between roots and shoots; a modification of the allocation of photoassimilates between the root and shoot as a consequence of inhibiting shoot growth; or a translocation of PGR from the point of application to the roots to directly influence root growth.
