Relationships between stem CO2 efflux, substrate supply, and growth in young loblolly pine trees

Informally Refereed

Abstract

We examined the relationships between stem CO2 efflux (Es), diameter

growth, and nonstructural carbohydrate concentration in loblolly pine trees. Carbohydrate

supply was altered via stem girdling during rapid stem growth in the

spring and after growth had ceased in the autumn. We hypothesized that substrate

type and availability control the seasonal variation and temperature sensitivity of

Es.
