早在十八世纪,科学家们就证实了植物体内存在诱导生根的化合物质,从而解释了当植物体受到束缚或刺激后(如环状剥皮等),伤口处膨大继而有根形成的现象。后来,经过对这类化合物的提取测定,证明它是一类植物生长调节物质,在植物体内可分布一种或多种,其中分布最 As early as the eighteenth century, scientists confirmed the presence of rooting-inducing compounds in plants, thus explaining the phenomenon of swelling and subsequent root formation at the wound when the plant is restrained or stimulated (eg, ring peeling). Later, after the extraction of these compounds was determined to prove that it is a class of plant growth regulating substances in the plant can be distributed in one or more, of which the distribution of the most
