Determination of Unfrozen Water in Winter Cereals at Subfreezing Temperatures

Abstract: The freezing of water in acclimated and nonacclimated cereals was studied using pulsed nuclear magnetic resonance spectroscopy. The quantity of unfreezable water per unit dry matter was not strongly dependent on the degree of cold acclimation. In contrast, the fraction of water frozen which was tolerated by nonacclimated winter cereals and by an acclimated spring wheat (Triticum aestivum L.) was less than in acclimated hardy cereals. The freezing curves had the following form: LT = LoATm/T + K LT and Lo are li… Show more

“…Pressure potential was obtained by subtracting cell osmotic pressure during intracellular freezing from that during extracellular freezing at a given temperature. The osmolality of expressed cell sap was estimated using an osmometer (Wescor, Logan, UT) or by using NMR methods to determine the melting point depression in intracellularly frozen samples (Gusta et al, 1975).…”

“…The sap was expressed using a manual leaf press. For grape pith and xylem, osmolality was determined using NMR methods by direct measurement of the melting point depression during thawing of the sample that had been cooled to -196°C (Gusta et al, 1975).…”
