Brassinosteroid preharvest treatments as a useful tool to increase crop yield and red colour in blood orange fruits.

ABSTRACT:

Introduction

Blood oranges are highly appreciated by consumers due to their attractive peel, red-colour juice, and their antioxidant and other health-beneficial properties. However, increased temperatures due to climate change compromise anthocyanin biosynthesis, depreciating their market value. Brassinosteroids (BRs) are plant hormones with important effects in plant adaptation to environmental stresses.

Materials and methods

The present experiment aimed to evaluate the effects of tree foliar treatments with different 24-epibrassinolide (24-BL) concentrations (0.01, 0.1, and 1 μM) on crop yield and fruit quality properties of the "Sanguinelli" blood oranges, with special emphasis on anthocyanin content in the peel and juice.
