Abstract

Dynamics of photosynthesis in leaflets of Azadirachta indica was evaluated through the analysis of polyphasic chlorophyll fluorescence OJIP kinetics. In the present study, a gradual decrease in ABS/CS (absorbance per cross section), TR/CS (trapped energy per cross section) and ET/CS (electron transfer per cross section) was noted from bottom to apical leaflets. On the basis of results, it is hypothesized that fully developed leaflets act as â€˜sourceâ€™ and young leaflets as â€˜sinkâ€™. The study indicates that age and pattern of leafletâ€™s arrangement influence photosynthesis in compound leaves of A. india.
