With regard to this, nanotechnology enables the

Today, the application of auxins in agriculture provides advantages such as longer time of action and stability of active agents, the minimization of the effects of biotic and abiotic stresses, and the control of

Auxins are plant-growth regulators (PGRs), influencing physiological processes from embryogenesis to the formation of new organs [12]. The main auxins that favor plant growth are 1
