Australian Journal of Agricultural Research, 1956
Detailed temperature measurements among grape-vines, and in the inversion layer in the air overhead, are presented for two nights on which frost damage occurred. The temperatures are related to the varying degrees of damage suffered by the vines. It is concluded that the critical vine-shoot temperature was about 28½°F a t the stage of development of ...

Plant Pathology, 1979
SUMMARY Widespread damage attributed to frost lift was seen in winter barley crops in Devon and Cornwall during late spring 1978. A break in the crown root system of plants had occurred. An affected crop of cv. Astrix in Devon yielded 3.5 t/ha; this was 1.8 t/ha less than an adjacent unaffected crop of the same cultivar.

A Conductivity Method for Screening Populations of Eucalypts for Frost Damage and Frost Tolerance
Australian Journal of Botany, 1986The assessment of frost tolerance of Eucalyptus leaf tissue by an electrical conductivity method is described. Leaf disc samples were exposed to freezing treatments in test tubes within a liquid cold bath with precise temperature control, and the conductivity of the disc leachate measured.

On the mechanics of frost damage to brick masonry
Computers & Structures, 1991Abstract This paper presents a computational model for the assessment of frost damage to brick masonry. Equivalent elastic parameters of masonry with brick units having orthotropic properties is first derived. It is then extended to frozen brick masonry by including ice within the pores.

Effects of some growth regulators on frost damage
Cryobiology, 1968Summary The sequence of freezing processes in fruit tree blossom and the possibilities of affecting them by application of growth regulators are discussed. Effects of exogenous growth regulators on frost damage to blossom are inconsistent. Their direct effects are negligible except when noxious.

Frost Damage to White Spruce Buds
Canadian Journal of Forest Research, 1972Unopened buds of white spruce (Piceaglauca (Moench) Voss) were damaged by late spring frost. At time of death of the apical meristem the buds were not ready for flushing. As expected on the basis of ground frosts, there was more damage among shorter trees than among taller trees, and more damage among open-grown trees than among understory trees.
