Abstract: Summary Cuttings from stock plants grown under continuous irradiance need a supply of borate for roots to develop. This requirement is alleviated, at least in part, by subsequent exposure of stock plants to periods of continuous darkness. Nevertheless, rooting capacity, as shown by responsiveness to supplied IBA, is enhanced by irradiating stock plants. Exposure of the region of regeneration to irradiance diminishes root formation, but exposure of the rest of the cutting enhances it in response to IBA. This effect is mediated via the leaves. In the absence of supplied auxin, irradiance of the leaves only enhances rooting when the hypocotyl is shaded.
