Toxic Concentrations

Soil salinity can severely reduce crop growth and yield. Many studies have investigated salinity tolerance mechanisms in cereals using phenotypes that are relatively easy to measure. The majority of these studies measured the accumulation of shoot Na+ and the effect this has on plant growth. However, plant growth is reduced immediately after exposure to NaCl before Na+ accumulates to toxic concentrations in the shoot. In this study, nondestructive and destructive measurements are used to evaluate the responses of 24 predominately Australian barley (Hordeum vulgare L.) lines at 0, 150 and 250 mM NaCl. Considerable variation for shoot tolerance mechanisms not related to ion toxicity (shoot ion-independent tolerance) was found, with some lines being able to maintain substantial growth rates under salt stress, whereas others stopped growing. Hordeum vulgare spp. spontaneum accessions and barley landraces predominantly had the best shoot ion independent tolerance, although two commercial cultivars, Fathom and Skiff, also had high tolerance. The tolerance of cv. Fathom may be caused by a recent introgression from H. vulgare L. spp. spontaneum. This study shows that the most salt-tolerant barley lines are those that contain both shoot ion-independent tolerance and the ability to exclude Na+ from the shoot (and thus maintain high K+ : Na+ ratios).

Seaweed Extracts

A cytokinin-containing seaweed extract, Nitrozyme™ (Nitrozyme1), was tested under field conditions over 4 yr for its effects on the growth and yield of barley (Hordeum vulgare L.). In 1986 and 1987, Nitrozyme did not increase yield and had no beneficial effects on growth of Harrington and Bonanza barley. In 1988 and 1989, the effects of Nitrozyme on barley (cv. Leduc) were compared against those of kinetin, a synthetic cytokinin. Neither Nitrozyme nor kinetin had an effect on growth or yield.Key words: Nitrozyme, seaweed extracts, cytokinins, kinetin, plant growth regulator, Hordeum vulgare L.

OAC Elmira is a high-yielding, disease-resistant, hardy winter barley adapted to Southern Ontario. OAC Elmira has good winter hardiness and high hectoliter weight. It has better disease resistance than any of the check cultivars and long straw with a lax, nodding head. It was developed by the Ontario Ministry of Agriculture and Food through the Crop Science Department of the University of Guelph. Key words: Hordeum vulgare L., high yield, disease resistance, winter hardiness

Experimental Soil

Uptake and translocation of radiocesium artificially added to sand soil cultivated with barley as affected by different rates of potassium were traced in outdoor pot experiment. Experimental soil was contaminated with 0.01 and 0.1 mM 137Cs equal to (200 and 400 Bq/kg) in the form of CsCl and incubated for 14 days prior to 150 days plant growth period. The transfer factor (TF) average values from soil-to-total biomass were found to range from 0.40 up to 0.53 as affected by interaction between tested treatments. Increasing K rates from 125 to 250 kg/ha markedly reduced the mean averages of TFs of 137Cs from soil-to-roots by about 24 to 68%, respectively and from soil-to-total biomass by about 36 and 74%, respectively lower than corresponding control. In all cases, the discrimination factor was below unity, indicating that Cs is less efficiently absorbed from soil than its nutrient analogue K.
