“…These observations are in accordance with reports that large ice crystals form in the intercellular spaces in the cortex (Levitt 1980), which causes separation and breakage of cell walls (Idle 1966;Mohr and Stein 1969).…”

The ultrastructure of cells in the cambial region of Salix dasyclados Wim. (clone 78056) was studied during the development of winter hardiness and the onset of cambial activity in spring. Plants were grown at relative growth rates (Re) of 8% and 12% respectively, resulting in different nitrogen content in the stems. Frost hardiness of the plants was estimated by standardized freezing tests. Plants with a higher nitrogen status ceased growth later and started re-growth earlier in spring than plants with lower nitrogen content. Differences in ability to withstand low temperatures during autumn and spring were found between plants grown in the two nutrient treatments. During the development of frost hardiness in the autumn, the number of meristematic cells in the cambial region decreased.

“…36 Fuchigami et al 37 observed that the changes in pectin composition in freeze-thawed carrots were comparatively slight where cleavage of cell walls was discovered along the middle lamella region of the wall. 38 Prestamo and Risueno 39 observed that the pectin content was higher in frozen carrots than in raw samples. They concluded that this was caused by the decrease in hardness because pectin was one of the main components of the cell wall, and the amount and composition of pectin might influence the structure and textural properties of tissues.…”

“…Our studies with tomato fruit (Mohr and Stein, 1969a) provided information on ice patterns formed in this tissue frozen at different rates, and on the extensiveness of fine structural changes within the cells of this relatively delicate tissue following various freeze-thaw regimes. The present paper reports our observations on freeze-thaw induced alterations to the fine structure of other plant tissues: rhubarb, Mung bean sprouts and figs.…”

Freeze‐thaw Damage to Protoplasmic Structure in High Moisture, Edible Plant Tissues

Three high moisture plant tissues, whose textural response to freeze-thawing differs noticeably, were studied ultrastructurally before and after controlled freeze-thaw regimes. Fine structural components of the protoplasm were usually disrupted extensively, although to varying degrees, depending on tissue type and freeze-thaw conditions. Possible reasons for the apparent protection in some of the material studied are discussed. It is concluded that protoplasmic structure probably plays an insignificant role in influencing the textural properties of high moisture, frozen-thawed plant tissues.
