Alternate Identifier:DOI PLACE HOLDER
Abstract:

Root damage, as relative electrolyte leakage, was assessed following winter freeze-thaw cycle experimental treatments in 2014 and 2015 on all Climate Change Across Seasons Experiment (CCASE) plots. Reference (or control) plots are shared with the collaborating Northern Forest DroughtNet experiment. There are six plots total (each 11 x 14m). Two are warmed 5 degrees C throughout the growing season (Plots 3 and 4). Two others are warmed 5 degrees C in the growing season and have snow removed during winter to induce soil freeze/thaw cycles (Plots 5 and 6). Four kilometers (2.5 mi) of heating cable are buried in the soil to warm these four plots. Two additional plots serve as controls for our experiment (Plots 1 and 2).

Analysis and results from these data are presented in Sanders-DeMott 2018.

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.

Description:

Root damage following winter was measured as relative electrolyte leakage immediately following snowmelt on April 16, 2014 and April 17, 2015 before warming treatment was initiated in each year. Root sampling for assessment of damage was conducted by removing four 10 cm x 10 cm samples of organic layer soil from each plot (n = 24 total) using a frame and soil knife. Organic layer depth ranged from 3-10 cm. Soils were transported on ice and stored at 4 °C until laboratory analyses were initiated (within 12-24 hours of sampling). Fine roots (<2 mm diameter) were extracted from soil and cleaned. Roots were cut into 2-3 cm long sections and divided into five replicates of ~150 mg per sample with 15 mL of 0.1% Triton X-100 detergent solution. Samples were agitated overnight and measured for solution conductivity (CON 110 Oakton Instruments, Vernon Hills, IL). Sample tubes were then autoclaved at 101 °C for 15 minutes to kill roots, agitated for another 24 hours, and re-measured for solution conductivity. Root damage as % relative electrolyte leakage was calculated as the ratio of conductivity due to root membrane ion leakage before and after being heat-killed.
