The growth of the primary root of a single gene dwarf mutantof Zea mays L., dwarf-1, is dependent upon gibberellic acidor one of its derivatives as a growth hormone. Moreover, forthe root to respond to gibberellin treatment both embryonicand mature tissues must contribute growth stimuli.

Cultures of Gibberella fujikuroi grown under continuous illuminationof 1800 lux incorporated over 60% more leucine into the gibberellinsthan dark controls. In the dark at a C/N ratio of 37.6 Ca++increased the incorporations of leucine into A3 to essentiallythe same level as the light-stimulated incorporation. The failureof Ca++ to increase gibberellin synthesis in the dark at a C/Nratio of 9.4 suggested that light and Ca++ were exerting theirregulatory roles at different sites.
