用类似生长素药剂处理植物可以引起多种生理效应,近来文献上已有记载。这些效应往往是受到药效的组织在当时所处的机能状态下对药剂的反应,它们的新陈代谢受到扰动的表现。而且随着使用药剂浓度的不同,反应也各自异样。对同一组织说药剂在低浓度时引起机能的促进,较高浓度就转为抑制甚或引起毒害,而各种组织对这种药剂的敏成程度也不一样,促进茎的伸长之浓度对根说已经是过高而对其伸长发生抑制了。这种相反的效应在使
Plants treated with auxin-like agents can cause a variety of physiological effects and have recently been documented in the literature. These effects are often the response of the pharmacopoeia to the agent under the prevailing state of functioning, and their metabolism is disturbed. And with the use of different concentrations of drugs, the reaction is also different. To the same organization, the agent causes the promotion of the function at low concentration, and the higher concentration turns to inhibit or even cause poisoning, and the sensitivity of various tissues to the agent is also different, and the concentration of promoting stem elongation It is already too high to curb its elongation. This opposite effect is making
