  Citation × Citation Citation Abstract Copy Title: Growth rate and phosphorus uptake of wheat (Triticum aestivum VILL., Host) as a function of soil water suction and soil temperature Author: Fazilat, Mohammad The effect of soil temperature and soil water suction on the rate of phosphorus uptake and growth rate of wheat (Triticum aestivum VILL. , Host) was studied. Plants were grown in perlite slabs separated from an osmotic solution by a semi-permeable membrane. Measurements were made at temperatures of 10.0, 18.3, 23.9, 32.2, and 35.0°C, and soil water suctions of 0.35 and 2.5 bars. Five week old wheat seedlings were exposed to these conditions. The dry weight of shoots and roots was determined at two day intervals. Plant material extracted was analyzed for phosphorus concentration. The color intensity was measured on a Bausch and Lomb spectronic 20 spectrophotometer of 420 millimicrons. In general, a constant growth rate, which was approached exponentially during the experimental period was found in all treatment combinations. Growth rate for both shoots and roots was slow at low root temperatures and had a maximum rate at a root temperature of 24.0°C. High soil water suction was a limiting factor in growth rate. Phosphorus concentration of shoots and roots was found to approach a constant value during the experimental period according to the equation y = a+be[superscript]-0.07t[superscript]3/2 where y is the phosphorus concentration, t is the time in days, and a and b are constants. Over the entire range of soil temperatures considered the phosphorus concentration of the shoots increased linearlly with the root temperature, but the phosphorus concentration of the roots slightly decreased by increasing soil temperature and did not increase until the root temperature was about 32.0°C. There was no evidence of much variation in percent of total phosphorus uptake transported to the shoot in the experiments. Trans location of phosphorus from roots to shoots did not appear to be a limiting factor for phosphorus uptake at the low root temperature. It was suggested that the low rates of phosphorus uptake at the low root temperatures resulted from the low level of metabolic activity.

• 88. [Article] The microbial stability of refrigerated intermediate moisture foods

  Citation × Citation Citation Abstract Copy Title: The microbial stability of refrigerated intermediate moisture foods Author: Li, Ken-yuon The lag phase, the specific growth rate, the minimum a [subscript w] required for growth and the temperature characteristic of Fsendomonas fluorescens, Brochothrix thermosphacta, Salmonella typhlmurium, Streptococcus faecalis and, Staphylococcus aureus have been studied in liquid model media under controlled temperature and a [subscript w] conditions. The results show that the lag phase increases and the specific growth rates decreases when the temperature is lowered or the a [subscript w] is reduced. The minimum a [subscript w] required for growth increases when the incubation temperature is lowered. At refrigeration temperature the minimum a [subscript w] for growth of mesophiles is higher than that of psychrotrophs. The temperature characteristic (representing the activation energy for growth) of psychrotrophs is lower than that of mesophiles, and therefore mesophiles are more sensitive to temperature changes. All of these growth parameters depend on the a [subscript w] controlling solute. The solute effect can be traced to the ability of the solute to penetrate into the cell and can be explained by the osmoregulatory mechanism. In general, it was found that the effect of the solute on these parameters had the order glycerol<NaCl<sucrose. A comparison of three models for the effect of temperature on growth rate (linear, square-root, and Arrhenius) showed that the linear model had both the advantage of simplicity and accuracy. In general, the Arrhenius model showed the poorest fit to experimental data. A predictive method was developed to assess the microbial stability of liquid model systems exposed to fluctuating temperatures. The strategy was to predict lag time and growth rate by different regression equations, and to estimate microbial growth using an integral function of the accumulated time. A lag time predictive model was developed using a linear relationship between lag time and reciprocal growth rate. A linear equation was used to predict growth rate as a function of temperature. The model was used to predict the growth of B. thermosphacta in liquid model media with low a [subscript w] and exposed to fluctuating temperatures. The predictions were acceptable at a 95% confidence level. This method will be used in future studies to predict the microbial stability of refrigerated foods exposed to temperature abuse.
