植物生长素是近30多年来新发展的一种人工合成、提纯或微生物培养的药剂。对植物生长能起调节、控制作用。用这类药剂适当处理植物某些器官,可以提早发芽,加快生根,提早成熟,提高产量。本试验采用“802”,“三十烷醇”,“C-751”,“萘乙酸”4种植物生长素,首次在 Auxin is a newly developed over the past 30 years a synthetic, purified or microbial culture of the agent. Plant growth can regulate and control. Appropriate treatment of such organs with certain organs of plants, can be early germination, accelerate rooting, early maturity and increase production. In this experiment, four kinds of auxin such as “802”, “triacontanol”, “C-751” and “naphthaleneacetic acid”
