Abstract

DISTRIBUTION OF ABSORBED SOLAR ENERGY IN SPECIES WITH DIFFERENT COROLLA COLOURS

The distribution of absorbed solar energy was studied both through mathematical modelling and experientially on plants of the species Papaver rhoeas L., Borago officinalis L., Oenothera biennis L. in the flowering phase. It was found that the radiation energy and heat transfer energy for the corolla model of red, blue and yellow colours are constant, and the evaporation energy of corolla varies and depends on the absorption energy of the corolla, so that the higher the absorption energy, the greater the evaporation energy. The energy of evaporation increases in the following order: corollas with blue coloration <corollas with red coloration <corollas with yellow coloration.

Keywords: solar energy, mathematical modelling, absorption, radiation, evaporation, heat transfer, heat balance, corolla.
