Changes in the Growth and Photoperiodic Sensitivity of Pharbitis nil Seedlings in Relation to Low Intensity Light
Year: 1963
Type: article
Abstract: 1. Incandescent light promotes hypocotyl growth and reduces the differentiation of leaf primordia in plumules. Daylight fluorescent light has little effect on axial growth.2. The effects of incandescent light upon axial growth are due primarily to the far-red contained in the light used. The irradiation times required for maximum responses are the same for both axial growth and floral inhibition. In addition, both processes are affected reversibly by red-far-red.3. The organ perceiving the light stimulus is the cotyledon.4. In the older seedlings, the incandescent light of low intensity affects neither axial growth nor photoperiodic sensitivity
