TITLE: Lodgepole-Pine LP-Needles-2 DESCRIPT

DOCUMENTATION_FORMAT: Plant

SAMPLE_ID: LP-Needles-2

PLANT_TYPE: Coniferous Tree

PLANT: Lodgepole Pine

LATIN_NAME: Pinus contorta

COLLECTION_LOCALITY: Yellowstone National Park, Wyoming

ORIGINAL_DONOR: Raymond Kokaly

SAMPLE_DESCRIPTION:

Reflectance of oven-dried needles of lodgepole pine (Pinus contorta) measured in the laboratory. The dried, green needles were stacked in a sample cup and the head of the spectrometer fiber optic cable was passed over the needles.

The needles were dried in an oven for 72 hours at 36 degrees Celsius. The vegetation was sampled in Yellowstone National Park and kept in a plastic bag, on ice, for four days until measured. As a result, some of the plant moisture was lost during the storage time. Also, some of the chlorophyll was likely degraded.

A related spectrum (sample ID = LP-Needles-1) of this collection of lodgepole needles was measured before oven drying the needles for 72 hours at 30 degrees Celsius. Fresh weight of the needles was 6.38 g and dry weight was 3.15 grams.
