Effect of growth regulators on overcoming the light inhibition on germination ofCucumis anguria L.

The effects of some growth regulators on the dark-germinating seeds of Cucumis anguria have been investigated. GA 3 , 6-BA and ethrel strongly promoted the germination of seeds kept in white light. GA 3 had no effect in counteracting the far red effect, but did counteract partially the blue light. Ethrel partially counteracted both the far red and blue light effect. No interaction could be found between red light and GA 3 or 6-BA.
