Zrożnicowana dostępność wody glebowej dla roślin w obrazach termalnych ich powierzchni

In this paper the thermal images of meadow plant cover in lysimeters with different soil water availability are analyzed. In the case of plants growing in conditions of limited soil water availability (pF>2,7) the highest differentiation of radiation temperature was noticed for the hours with high solar radiation. In comfort soil water conditions, mean values of standard deviation of plant surface temperature were considerably lower. It indicates that intensive transpiration causes diminishing of the differences of plant cover radiation temperature.
