A method and apparatus are disclosed for assessing gas exchange of plants. The method includes receiving in a gas analyzer a plurality of test air samples from a leaf chamber corresponding respectively to first and second plant leaf samples received separately and in sequence in the leaf chamber while being exposed to light to form the first and second test air samples, the first and second test air samples being received in sequence in the gas analyzer as an integrated gas stream, and the gas analyzer analyzing the integrated gas stream as it flows therethrough. The measuring apparatus includes a leaf chamber for receiving therein a plant leaf sample to be tested, a pump communicating with the leaf chamber for supplying air thereto, and an analyzer communicating with the leaf chamber for receiving air therefrom and for analyzing the air received.
A measuring apparatus for assessing gas exchange of plants, comprising a leaf chamber for receiving therein a plant leaf sample to be tested, a pump communicating with the leaf chamber for supplying air thereto, an analyzer communicating with the leaf chamber for receiving air therefrom and for analyzing the air received, wherein the pump is configured to be filled with a single charge of air and to supply plural doses of air from that single charge each for sequentially testing a respective plant leaf sample of a plurality of plant leaf samples.
An apparatus for assessing gas exchange of plants, comprising a leaf chamber configured to receive a plurality of plant leaf samples separately and sequentially therein and to expose the plant leaf samples to light while passing air through the leaf chamber to form a corresponding plurality of test air samples, the leaf chamber being openable for removal of one of the plurality of plant leaf samples therefrom and for receiving therein a next plant leaf sample of the plurality thereof, a gas analyzer configured to receive from the leaf chamber the plurality of test air samples in sequence and to analyze the plurality of test air samples in the sequence, and a data processor configured to receive analysis data from the gas analyzer, to process the analysis data to produce a test result for each of the plant leaf samples, and to combine the test results for the plant leaf samples to generate an average test result for the plant leaf samples.
