Effect of Plant Growth Regulators on Cotton Seedling Root Growth Parameters and Enzyme Activity.

ABSTRACT: It is well known that the survival rate of cotton seedlings is low, and the growth and development status at this stage is crucial to improve productivity. Plant hormones are important factors that promote the growth and development of cotton seedlings. Growth regulators have the same function as plant hormones. The purpose of this research is to explore the effects of different concentrations of growth regulators on cotton root morphological parameters and enzyme activities, and to find suitable plant growth regulators and their optimal concentrations to improve the growth of the cotton seedling root system. Three cotton varieties, "Zhongmian 619" (Z619), "Xinluzao 27" (Z27), and "Xinluzao 39" (Z39), and three growth regulators, gibberellin (GA₃), salicylic acid (SA), and paclo
