Plant growth influenced by photosynthetic irradiance and temperature: Part II: Biomass estimation for nonstandard conditions

Plant growth for standard environmental conditions is well described in the modified logistic growth equation (MOLOGE) presented in part I of the paper. Part II develops this idea for nonstandard environmental conditions. The comparative method for biomass estimation (COMBE) makes it possible to estimate the biomass of a plant cultivated in variable growth conditions. An unlimited number of factors characterizing nonstandard conditions can be taken into account in the method. COMBE was tested on lettuce cultivated in phytotrons, where plant growth depended on different values of irradiance and temperature.
