1960年,西德E.Merck公司首次合成了一类新型的植物生长调节剂,芴-9-羧酸及其衍生物,1964年正式发表,1965年起被称为整形素(morphactins)。此后,在此类化合物的基本性能和生理作用方面,发表了大量的研究报导。现在,在西德、美国和英国都有几种以整形素为有效成份的制剂或与其它药剂配成的复合制剂,作为除草剂和植物生长调节剂的商品出售。现已证明,这类植物生长调节剂在植物的生长、发育、成熟、器官脱落等方面具有多种效能,但整形素的主要作用是延缓植物生长发育和破坏向性(向光性、向地性)生长。从其抑制植物生长的特点来看,它具有抗
In 1960, West Germany E. Merck Company for the first time synthesized a new type of plant growth regulators, fluorene-9-carboxylic acid and its derivatives, was officially published in 1964, 1965 was called the morin (morphactins). Since then, a large number of studies have been published on the basic properties and physiological roles of such compounds. Now, in West Germany, the United States and the United Kingdom, there are several preparations that are based on the action of an ortho-melanin or a combination of other agents, which are marketed as herbicides and plant growth regulators. It has been demonstrated that these plant growth regulators have various efficacies in the growth, development, maturation and organ shedding of plants, but the main function of them is to retard the growth and destructiveness of plants (toward light, Sexual) growth. It has resistance from its inhibition of plant growth
