Applied ethylene influences the growth of etiolated pea stem sections cut from untreated plants, but has no effect on (14)C-indoleacetic acid uptake, polar transport or destruction. However, the capacity of the polar auxin transport system is markedly reduced in sections cut from plants grown in ethylene, while the velocity of auxin transport is unchanged under these conditions. Inhibition of the polar transport system by ethylene could underlie certain responses in which the gas produces symptoms of auxin deficiency.
施加乙烯会影响从未经处理的植物上切下的黄化豌豆茎段的生长,但对¹⁴C-吲哚乙酸的吸收、极性运输或破坏没有影响。然而,在乙烯环境中生长的植物切下的茎段中,极性生长素运输系统的能力显著降低,而在这些条件下生长素运输的速度不变。乙烯对极性运输系统的抑制可能是该气体产生生长素缺乏症状的某些反应的基础。
