Abstract
Phytohormone is a key regulator of plant growth and development. It has important effects on plant under biotic and abiotic stresses. However, the dose control of phytohormone is always a difficult problem in the application process, which limits the application range of phytohormone. Nanotechnology, because of its characteristics of controlled release, targeted therapy, non-pollution, high adsorption, lower volatilization of active substances, and low dosage of drug, comes into researchers’ vision. Nanomaterials were directly applicated on crops at the early stage, and then active substances, such as pesticides, were encapsulated with nanomaterials, also achieved good results in the field. Currently, more and more attentions have been paid to nano-enabled delivery of phytohormones to plants, and formed a new field in agriculture. In present work, we reviewed the existing literatures, focused on the important regulatory roles of phytohormones in plant growth and development and their application potential, and the development and application prospect of nanomaterials combined with phytohormones were also have been discussed.
