Importance of various plant growth regulators in kinnow (Citrus reticulate Blanco)

Abstract

Plant hormones are a tremendously imperative cause in the incorporation of development activities. Ecological factors often have inductive effects, causing changes in the metabolism and distribution of hormones in the plant. In addition, they regulate the expression of the internal genetic potential of plants. Control of gene expression has been demonstrated for phytohormones at the transcriptional and translational levels. In adding up, hormone receptors and specific binding proteins for certain hormones have been identified on the surface of the membrane. The use of the growth regulators has become an essential component of agronomic modus operands for most crops and in particular for fruit plants. So, in fruit crops, excessive fruit drop can be controlled by the exogenous application of plant growth regulators. Auxin and Gibberellins are widely used to control fruit drop and to improve fruit quality. Maturation process from fruit set to ripening and final delivery to the customer, several agents are responsible for the elimination of certain fruits from hardening to final maturity. In this review, we focus on the main functions of plant growth regulators in Kinnow mandarin production.
