Hildebrandt等曾发现植物生长控制剂对植物肿瘤或病毒所致瘤组织有很大影响。植物生长控制剂在低浓度时有刺激植物细胞生长的作用,反之,在高浓度时则有抑制作用。植物生长控制剂并具有对不同种类的植物细胞有不同的作用,如2,4-D(Ⅰ),α-萘乙酸(Ⅱ)等化合物在适当浓度时对某些植物起抑制生长甚至杀灭作用, 同时对另一些植物则影响甚微。 Hildebrandt and others have found that plant growth control agents on plant tumors or virus-induced tumor tissue has a great impact. Plant growth regulators have the effect of stimulating the growth of plant cells at low concentrations and, conversely, inhibitory effects at high concentrations. Plant growth control agents and have different types of plant cells have different effects, such as 2,4-D (Ⅰ), α-naphthalene acetic acid (Ⅱ) and other compounds in the appropriate concentration of certain plants growth inhibition or even kill While having little effect on other plants.
