Abstract

Plant growth regulators (PGR) play a crucial role in the improvement of fruit appearance, the regulation of intrinsic quality, and the accumulation and metabolism of nutrients.In recent years, the impact of PGR on fruit quality has received increasing attention.This review summarizes the types of PGR and their effects on the appearance quality, intrinsic physicochemical and nutritional quality, secondary metabolites, and safety quality of fruits.The fruits quality includes the following indices such as shape index, fruit weight, the contents of sugar, acidity, total soluble solid, vitamin C, mineral elements, amino acids and proteins, as well as the safety quality.Secondary metabolites include flavonoids and aroma components.Meanwhile, the mechanisms by which different types of PGR affect fruit quality are also discussed.It is found that the effects of the same PGR on fruit quality vary depending on the type of fruits, application time, and concentrations.There are differences in the regulatory mechanisms of different PGRs on various qualities of fruits.Reasonable use of PGR can improve fruit quality, but improper use probably affects the quality of fruits and even cause potential risks to environment and humans.This article will provide some references for the use of PGR reasonably in the process of fruit production as well as the development and application of green and efficient PGR.
