Abstract

An apparatus for continuous measurement of CO_2 gas-exchange in regard to a whole forest tree in the field is described. The CO_2 gas-exchange rate is determined in an open system by an infra-red gas analyser. The air temperature inside an assimilation chamber can either automatically track ambient air temperature or be held at constant set points. The measuring system is controlled by a microcomputer according to predetermined set points. All data in the continuously operating gas-exchange system are successively monitored by devices such as the CRT-display and analog recorder. The microcomputer can also acquire a large amount of data for subsequent computer analysis. This apparatus has been used successfully for a forest tree of Chamaecyparis obtusa (Siebold & Zucc.) Endl.
