In this article:
The present paper describes the hastening by up to 2 weeks of the onset of ripening of a seedless and a seeded variety of grape by the growth retardant, methyl 2-(ureidooxy) propionate.
Terminal and lateral shoot growth was inhibited.
Ripening of berries was advanced as measured by development of colour, and changes in titratable acid and reducing sugar content.
The earlier ripening of the berries may have been due to hormonal changes but the advancement was much greater than that found previously with abscisic acid or ethylene applied during the slow growth stage of berry development.
