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 ‘source’ and young leaflets as ‘sink’. The study indicates that age and pattern of leaflet’s arrangement influence photosynthesis in compound leaves of A. india.
