Understanding plant growth regulators their interplay

Plant hormones (also known as phyto-hormones) are naturally occurring organic substances lopment in very low concentrations and whose action may be involved in sites far from their origin Hormones helps in the formation of flowers stems leaves the shedding of leaves and the development and ripening of fruit Hormones are crucial

The role of gibberellin signalling in plant responses to

Hormones thus have an important role in the plant's response to abiotic stress such as drought shading flooding or low temperature from which the plant may attempt to escape by outgrowing the stress e g shade avoidance (Franklin 2008) and in some cases flooding (Bailey-Serres and Voesenek 2010) or more commonly may result in reduced

Role of growth substances

protected by judicious use of plant growth hormones Plant growth hormones are organic substances produced naturally in the higher plants controlling growth or other physiological functions at a site remote from its place of production and active in minute amounts Hormones usually move within plant from a site of production to site of action
