Comparison of methods for estimating surface area of water-stressed and fully hydrate pine needle segments for gas exchange analysis

A nondestructive technique for repeatedly estimating total surface area of water-stressed pine (Pinus taeda L.) fascicle segments was evaluated. Fascicle radius was measured with a digital caliper and needle surface area calculated on the assumption that the needles were segments of a cylinder. High...
