Multiple Element Limitation in Northern Hardwood Ecosystems (MELNHE): Foliar Gas Exchange

General Information

Data Package:
Local Identifier:	knb-lter-hbr.335.1
Title:	Multiple Element Limitation in Northern Hardwood Ecosystems (MELNHE): Foliar Gas Exchange
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Gas exchange was measured for comparison with maple sap sugar concentration. Sugars maple (Acer saccharum) was the primary species collected for this reason. The exception was C8 Ca and control where yellow birch (Betula alleghaniensis) and American beech (Fagus grandifolia) were sampled. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Methods and protocols used in the collection of this data package

Description:

Foliar gas exchange (photosynthesis & conductivity) were measured for the two trees with the highest average sap sugar concentration (as sampled in the winter of 2013) and the two trees with the lowest average sugar concentration in each plot. Trees were chosen randomly if there were more than two trees with the same sap sweetness. At least 15 sun-exposed leaves from the upper canopy were collected from each tree using a 12 gauge shotgun. Only leaves free from shot holes, disease and insect herbivory were used. Foliage was sampled between 10 am and 2 pm on sunny days to ensure the leaves were dry and photosynthesizing. The removed branches were immediately placed in water to sustain transpiration for gas exchange measurements. A single healthy leaf from each tree was sampled for potential photosynthesis and stomatal conductance within a few minutes of being shot down, while it was still attached to the branch (Schaberg et al., 1997). Leaf gas exchange was measured with a LI 6400 (Licor Inc., Lincoln, NE) using a 6400-02B LED light source cuvette on 6 cm2 of leaf area. Environmental conditions in the chamber during measurement were maintained at a temperature of 26 C, 400 µmol mol-1 CO2 concentration, 500 µmol s-1 flow rate, and 1800 µmol m-2 s-1 photosynthetically active radiation. Ten measurements were taken for each leaf and averaged for potential photosynthesis and stomatal conductance.
