A low-temperature freezing system to study the effects of temperatures to -70 {degrees}C on trees in situ.


The ability to determine winter frost resistance of woody plants is limited for two reasons: (1) assessment of frost damage in midwinter is extremely difficult because results obtained by the currently available viability assays deviate greatly and (2) equipment that allows plants to be frozen at controlled freezing and thawing rates to below the midwinter… (More)
