Abstract

Temporal oscillations in morphological, physiological and biochemical parameters of plants are ubiquitous. Rhythmic phenomena in photosynthesis have been, found to be endogenous in nature and have been studied in algae as well as in higher plants (Edmunds, 1984; Sweeney, 1979; Lonergan, 1984b; Sweeney and Prezelin, 1978). Among the O2 evolving photosynthetic organisms, with the exception or cyanobacteria a large number of algal species representing almost all major taxonomic groups seem to exhibit rhythmic property in their photosynthetic capacity. However, the number of reports on photosynthesis rhythms in higher plants is limited to only a few species. Observations on the rhythmicity in photosynthesis have been made both under field and laboratory growth conditions. Time-dependent reversible variations in the chloroplast shape, movement and in the ultrastructure of thylakoid membranes in the case of algal cells have been investigated in detail (Sweeney, 1979).
