[Detecting leaf and twig temperature of some trees by using thermography].

Noninvasive detection of temperature with thermography from natural things has been used in many fields and it was attempted to detect the temperature for leaves and branches of trees in the present paper. Leaf and twig temperatures were monitored during the increasing process of temperature under the direct sunshine heating. The difference of specific heat and latent heat from leaves and twigs caused by different water content and transpiration capacity were measured.
