As we enter the flower induction stage different factor control the amount of flowering for the next season. Gibberellic acid (GA) is a strong inhibitor for the flowering genes in Citrus. The aim of the study was to determine to what length GA has got an influence. GA was applied on citrus bud and the genetics analyzed and more Leafy mRNA were transcribed in these buds.

However, more Flowering locus T (FT) genes were still transcribed in the buds compared to leaves. This article is important for growers and FFC consultants to understand that recommendations made during the season (thinning etc.) has got a major influence in plants gene to express flowers for the next season.
