An in situ approach to characterizing photosynthetic gas exchange of rice panicle.

ABSTRACT:

Background

Photosynthesis of reproductive organs in C₃ cereals is generally regarded as important to crop yield. Whereas, photosynthetic characteristics of reproductive organs are much less understood as compared to leaf photosynthesis, mainly due to methodological limitations. To date, many indirect methods have been developed to study photosynthesis of reproductive organs and its contribution to grain yield, such as organ shading, application of herbicides and photosynthetic measurement of excised organs or tissues, which might be intrusive and cause biases. Thus, a robust and in situ approach needs to be developed.

Results

Here we report the development of a custom-built panicle photosynthesis chamber (P-chamber), which can be connected to standard infrared gas
