In the main experiment, sodium chloride treatment was imposed on two varieties of H. vulgare during early tillering and continued until grain formation.

Young barley plants, Hordeum vulgare cv. Chevron, were subjected to a sodium chloride concentration of 100 m-equiv/l. In a "continued" treatment, the salinity stress was maintained for 15 days. In a "removed" treatment, sodium chloride was removed from the substrate after 5 days, and the subsequent response was studied over a period of 10 days.

The combined effects of acetic acid and mustard flour were investigated to ascertain their impact on Escherichia coli O157:H7 stored at 5 and 22°C. Samples were prepared with various concentrations of acetic acid (0, 0.25, 0.5, 0.75, and 1% [vol/vol]) combined with 10% (wt/vol) Baltimore or Coleman mustard flour and 2% (fixed; wt/vol) sodium chloride. An acid-adapted mixture of three E. coli O157:H7 strains (106 to 107 CFU/ml) was inoculated into prepared mustard samples that were stored at 5 and 22°C, and samples were assayed periodically for the survival of E. coli O157:H7. The numbers of E. coli O157:H7 were reduced much more rapidly at 22°C than at 5°C. E. coli O157:H7 was rapidly reduced to below the detection limit (<0.3 log10 CFU/ml) after 1 day at 22°C, whereas it survived for up to 5 days at 5°C. There was no synergistic or additive effect with regard to the killing of E. coli O157:H7 with the addition of small amounts of acetic acid to the mustard flour. When stored at 5°C, mustard in combination with 0.25 (M-0.25), 0.5 (M-0.5), and 0.75% (M-0.75) acetic acid exerted less antimicrobial activity than the control (M-0). The order of lethality at 5°C was generally M-0.25 = M-0.5 < M-0.75 = M-0 < M-1. The addition of small amounts of acetic acid (<0.75%) to mustard retards the reduction of E. coli O157:H7. Statistical reduction in populations of E. coli O157:H7 (P < 0.05) was enhanced relative to that of the control (mustard alone) only with the addition of 1% acetic acid. This information may help mustard manufacturers to understand the antimicrobial activity associated with use of mustard flour in combination with acetic acid.

The response of T. domingensis, a large emergent macrophyte, to salinity and manganese was studied under glasshouse conditions. Plants were grown in saline solutions ranging in concentration from 0.5 to 100 mM NaCI. and in manganese sulfate solutions ranging in concentration from 0.01 to 10 mM. Growth was reduced slightly at 50 mM NaCl and severely at 100 mM NaC1, suggesting that T. domingensis is moderately salt tolerant. Plant parts had highest chloride levels at 25 mM NaCl and highest sodium levels at 100 mM NaCl. The highest sodium chloride treatment reduced the level of potassium in the rhizomes, but not in roots or leaves. Sodium chloride had no effect on the concentration of nitrate in organs, but total nitrogen levels in roots and rhizomes increased at 100 mM NaCI. Sodium was considered to be more toxic than chloride. Growth in manganese solutions was unaffected except at the highest concentration used. Manganese accumulated quickly in leaves to levels which would be toxic to livestock; leaves retaining over 70% of the total manganese in the plant. Manganese applied at high concentrations substantially reduced the levels of calcium, magnesium and phosphorus in the leaves. In a field experiment, there were seasonal changes in the levels of selected elements in the leaves of T. domingensis. During leaf senescence. concentrations of sodium, manganese and calcium increased by 20-80%, but levels of phosphorus, nitrogen, potassium and maganesium fell by 65-84%. The results are discussed in relation to the use of T. domingensis in Hastewater reclamation.
