Bioregulators Application in Pear Production
2017
Costa, Guglielmo
This short review report the results obtained with the main plant growth regulators/plant bioregulators (PGRs or PBRs) that are currently tested or used as registered pre-harvest and post-harvest compounds. The PBRs used in pre-harvest concern the regulation of fruit setting, bearing, fruit thinning and of shoot growth control. The auxin-like compounds are mainly used for fruit set and for pre-harvest drop control; Gibberellins for fruit set; auxins and citokinins for fruit thinning/quality improvement and prohexadione-Ca (Regalis) for shoot growth and fire-blight control. The PBRs for improving fruit quality and storability can be used in pre- and post-harvest. Aminoethoxyvinylglycine (AVG) is used in pre-harvest while 1- methylcyclopropene (1-MCP) can be used in cold storage room or, in some countries, also in pre-harvest (Harvista) to affect fruit post-harvest maturation and storability management.
