The isolation and properties of a fungicidal compound present in seedlings of Vicia faba
The isolation of a fungicidal compound in 0.001% yield from healthy broad bean seedlings by extraction with benzene is described. After column chromatography, purification was achieved by low temperature recry...

Studies with Plant Growth Inhibitors
In this paper I propose to deal with three aspects of our research at Wye all of which, in their different ways, are concerned with plant growth inhibition.

The root cap and control of root elongation in Zea mays L. seedlings exposed to white light
Light-induced inhibition of the elongation of primary roots of Zea mays seedlings is dependent upon the perception of light by the root cap. Separate exposure of detached root caps and roots from which root caps ...

Ethylene production by cress roots and excised cress root segments and its inhibition by 3,5-diiodo-4-hydroxybenzoic acid
3,5-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 segmen...

Abscisic acid and the response of the roots of Zea mays L. seedlings to gravity
Exogeneous application of abscisic acid (ABA) to intact roots of LG 11 maize seedlings inhibits root elongation and induces bending of the root in response to gravity in darkness, even though the roots of thes...

Promotion of cress root elongation in white light by 3,5-diiodo-4-hydroxybenzoic acid
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 ...

The role of the root cap in the response of the primary roots of Zea mays L. seedlings to white light and to gravity
Investigations into the relationship between the light-induced inhibition of root elongation and the response of Zea mays primary roots to gravity have revealed a close similarity between growth-inhibiting factor...

The effects of 3,5-diiodo-4-hydroxybenzoic acid on the oxidation of IAA and auxin-induced ethylene production by cress root segments
In previous research here, 3,5-diiodo-4-hydroxybenzoic acid (DIHB) was shown to promote the elongation of roots of cress (Lepidium sativum) seedlings growing in light, and to inhibit the auxin-induced production ...

The effect of certain phenolic acids on the growth and ethylene production of cress seedling roots
Previous studies showed that 3,5-diiodo-4-hydroxybenzoic acid (DIHB) promotes the root growth of cress seedlings (Lepidium sativum) in the light and also inhibits the production of ethylene by this tissue. Studie...

Root Growth Inhibitors
Our interest in this subject arose from the discovery (43) of the selective herbicides, 3,5-diiodo-4-hydroxybenzonitrile (ioxynil) and the dibromo derivative (bromoxynil), both of which are widely used in agri...
