Abstract:
The phototropic response of dark-grown seedling of radish (Paphanus sativus L.) was slow to the stimulation by unilateral ill umination with blue light.Light preirradiation could modify the phototropic capability.The resulation by blue light was significant,but that by red or farred light was not.Phototropic capability of the etiolated seedling of radish was enhanced with in 0-2h by blue-light preirradiation,but tended to be gradually satured with in 2-12h pretreatment.The enhanced phototropic capability by 2h blue light could be kept within 1h,and declined gradually under 0-8h dark condition.The regulation system of phototropic capability by pure blue light in radish would be useful for the molecular study of phototropism.
