PREDICTION OF PHOTOSYNTHETIC RESPONSES BY MATHEMATICAL MODEL

Plant photosynthetic responses such as photosynthesis, transpiration rate and stomatal conductance are interrelated. There is a definite tendency for variability between photosynthetic responses and leaf positions at different branches. The variability is in the form of diurnal variations relative to the leaf positions of photosynthesis, transpiration and stomatal conductance on the same branch of Jatropha curcas plants. This research paper presented shows that the correlation between plant photosynthetic responses through mathematical modeling. Through the proposed model, the characteristic of plant responses constants for jatropha plants were calculated and the different deviation from their observed value was calculated by calculating the different plant photosynthetic parameters. In the comparative study, the average deviation of the photosynthetic responses ranged from 1.69 - 13.21. This model can be easily used in calculating plant photosynthetic responses according to their leaf positions on the branches of other plants.
