How do you calculate photothermal quotient?
The photothermal ratio is calculated by dividing the Daily Light Integral (photosynthetic photon flux density integrated over a day; DLI) plants are exposed to by a baseline daily temperature(Tb). PTR = DLI / Tb. Units are therefore mol quanta m−2 day−1 °C−1. What is photothermal unit? The photothermal unit concept provides a reliable index for…
