The involvement of PsTCP genes in hormone-mediated process of bud dormancy release in tree peony (Paeonia suffruticosa).

ABSTRACT:

Background

The complete dormancy release determines the quality of bud break, flowering and fruiting. While in tree peony (Paeonia suffruticosa Andr.), the insufficient accumulation of cold temperatures results in incomplete dormancy release and poor flowering quality.

Results

In order to investigate if phytohormone can replace the chilling requirement in south China and other similar regions, the roles of fluridone (Flu), gibberellin (GA₃), and their combination in the bud dormancy release process were analyzed. It demonstrated that the application of exogenous GA₃ and the mixture significantly expedited the dormancy release of tree peony at 23℃. Furthermore, the endogenous hormone levels provided evidence for the substantial impact of exogenous GA
