RT Journal Article SR Electronic T1 Portable refrigerator | freezer provides stable temperature for plant material collection JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 40 OP 44 DO 10.2979/NPJ.2008.9.1.40 VO 9 IS 1 A1 Anthony S Davis A1 Martin-Michel Gauthier YR 2008 UL http://npj.uwpress.org/content/9/1/40.abstract AB In a simple evaluation we found that a portable refrigerator/freezer unit, powered by the 12v DC connection in a vehicle, maintained a constant and colder temperature than a similarly sized recreation-style cooler filled with ice. Such a device may have utility for preserving the quality of seeds and cuttings collected in the field.
