A hand‐held porometer for rapid assessment of leaf conductance in wheat

Grain yield in bread wheat ( Triticum aestivum L.) has been associated with variation in leaf stomatal conductance. However, breeding programs have been reluctant to exploit this relationship because the equipment required is either too costly or too slow for assessing large breeding populations. This study compared a new hand‐held viscous‐flow porometer against a steady‐state diffusion porometer for leaf conductance measured on progeny derived...
