Use of auxin to delay ripening: sensory and biochemical evaluation of Cabernet Sauvignon and Shiraz

Background and Aims Climate change is prompting earlier grape ripening and harvest compression causing quality and logistical problems for growers and winemakers. Application of 1-naphthalene acetic acid (NAA) offers a management tool to delay ripening and expand the harvest window. This study extends previous findings about the effect of NAA on Shiraz fruit and wine composition and provides the first analysis of NAA-induced ripening delay of...
