Rapid thermal method for early diagnosis of the physiological state of Scots pine trees

Resumo

Trends in stem temperature of Scots pine trees in different life states are described. Any substantial disturbances of water flow in the roots, stem, or crown have an immediate effect on the stem temperature. This temperature shows a strong inverse correlation with the state of the tree, with the coefficient of determination ranging from 0.710 to 0.974. The method of assessing the physiological state of trees by temperature parameters allows early diagnosis of decline in the viability of conifers.
