Mp. Fuller et M. Wisniewski, THE USE OF INFRARED THERMAL IMAGING IN THE STUDY OF ICE NUCLEATION AND FREEZING OF PLANTS, Journal of thermal biology, 23(2), 1998, pp. 81-89
The results of using an infrared camera, Inframetrics Model 760 LW (In
frametrics, Billerica, MA, USA) and imaging system to record the ice n
ucleation events in two crop species, potato and cauliflower, is repor
ted. Exotherms were easily visualised by a colour change on videotape.
The influence of surface water on potato foliage was illustrated to s
timulate warm temperature ice nucleation whilst the absence of surface
water allowed relatively deep supercooling (to -8 degrees C). The tec
hnique enabled confirmation of the discrete freezing ability of caulif
lower florets on an intact curd. (C) 1998 Elsevier Science Ltd. All ri
