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.

Key words: ethylene, plant morphogensis, role

摘要： 乙烯对植物生长发育的许多方面,如根的形成、花的诱导、器官衰老脱落均起重要的调节作用。拟南芥根表皮中的乙烯是根毛发育的一个正调控因子。兰花授粉诱导花被萎蔫过程的早期反应是提高了对内源乙烯水平的敏感性。
