Abstract: Ethylene plays an important regulatory role in many aspects in the growth and development of plants such as root formation, floral induction, organ senescence and abscission, and so on. Studies indicated that ethylene is a positive regulator of root hair development in the Arabidopsis root epidermis, and the early reaction of the process of post-pollination perianth wilting of orchids increases the sensitivity to endogenous levels of ethylene.
