✦ Synopsis

The effect of low concentrations of 3,5-diiodo-4-hydroxybenzoic acid (DIHB) in promoting the elongation of light-exposed cress (Lepidium sativum L.) roots has been further examined. Aeration of the DIHB solution in which the roots were grown largely removed the growth promotion. The addition of ethylene or the ethylene precursor methionine to the solution caused marked inhibition of root elongation and this effect was relieved by DIHB.

Diiodo-4-hydroxybenzoic acid (DIHB) has been shown to exert an inhibitory effect on the formation of ethylene by the roots of intact cress Lepidium sativum seedlings in light, and by excised cress root segments.

In previous research here, 3,5-diiodo-4hydroxybenzoic acid (DIHB) was shown to promote the elongation of roots of cress (Lepidium sativum) seedlings growing in light, and to inhibit the auxininduced production of ethylene in this tissue.
