TITLE: Engelmann-Spruce ES-Needls-1 DESCRIPT
DOCUMENTATION_FORMAT: PLANT
SAMPLE_ID: ES-Needls-1
PLANT_TYPE: Coniferous Tree
PLANT: Engelmann Spruce
LATIN_NAME: Picea engelmannii
COLLECTION_LOCALITY: Yellowstone National Park, Wyoming
ORIGINAL_DONOR: Raymond Kokaly
SAMPLE_DESCRIPTION:
Reflectance of needles of Engelmann spruce (Picea engelmannii) measured in the laboratory. The blue-green needles were stacked in a sample cup and the head of the spectrometer fiber optic cable was passed over the needles.
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.
