Abstract

Trials with Euphatorium odoratum, Euphorbia heterophylla, E. hirta, Tephrosia purpurea and Tridax procumbens showed that photosynthetic processes and rate of photosynthesis decreased with increasing leaf age. For E. heterophylla a good correlation was evident between the photosynthetic rate, stomatal resistance, protein content, transpiration rate, biomass, photosynthetic pigments and nitrate reductase activity.
