Abstract

Nonfoliar gas exchange provides a noninvasive way to measure photosynthesis and other gas exchange parameters, enabling the assessment of their potential contribution to yield. Photosynthesis in nonfoliar material has been gaining increasing attention due to its contribution to yield, especially under conditions when leaf photosynthesis is compromised. Here, we provide methods and approaches along with examples of measuring gas exchange in nonfoliar material using a specialized chamber.

Keywords: Ears; Gas exchange; Net CO2 assimilation rate (A); Nonfoliar photosynthesis; Pods; Stems; Stomatal conductance (gs).
