Interaction between External and Internal Conditions in the Development of Photosynthetic Features in a Grass Leaf: II. REVERSIBILITY OF LIGHT-INDUCED RESPONSES AS A FUNCTION OF DEVELOPMENTAL STAGES

摘要

Lolium multiflorum plants were grown under a low- or high-light regime until third leaves had emerged to one-third their final length and then were transferred to a contrasting light regime. At this stage, the leaf possesses a tissue-age gradient from tip to base; thus, the reversibility of light-acclimated responses as a function of the degree of differentiation was analyzed in individual leaves.
