众所周知,细胞分裂素类物质具有显著促进细胞分裂、加快生长和延缓衰老的功能,但是,由于其人工合成造价高而难以在农业生产上大面积应用.最近几年,日本和美国从苯脲衍生物中筛选出一种价廉且活性高的细胞分裂素类物质——CPPU,并在大田作物、果树、蔬菜和花卉上进行了试验,获得了巨大成功.它被认为是一种迄今为止可供使用最为有效的生长调节剂. It is well-known that cytokinins have the function of significantly promoting cell division, accelerating growth and delaying aging, but are hard to be widely applied in agricultural production because of their high synthetic cost. In recent years, Japan and the United States, The result was a huge success in screening for a cheap and highly active cytokinin called CPPU that has been tested on field crops, fruit trees, vegetables and flowers and is considered to be a hitherto For the most effective use of growth regulators.
