Root Buds

Effects of repeated late-fall applications of the isopropylamine salt of glyphosate at 1.7 kg ae/ha plus 0.5% (v/v) surfactant on adventitious root buds, thickened propagative roots (> 1.3 mm diam), and shoot density of Canada thistle were studied in continuous hard red spring wheat over a 4-yr period. Glyphosate suppressed Canada thistle shoot density more quickly and to a greater extent than thickened root fresh weight or root bud number. A single fall application of glyphosate drastically decreased Canada thistle shoot density for 1 yr after treatment. However, shoot density was the same as the untreated control by 2 yr after a single fall treatment. Two consecutive late-fall applications of glyphosate in 2 yr decreased Canada thistle shoot density 94% in the fall 1 yr after the last treatment. Glyphosate reduced Canada thistle thickened root fresh weight 70% in the first fall 1 yr after a single fall treatment. However, 2 yr after a single fall application of glyphosate, root fresh weight equalled the controls. Two consecutive fall applications of glyphosate reduced thickened root fresh weight 77% 1 yr after the second treatment.

Abstract A monitoring program was conducted for trace elements in Western Canadian Hard Red Spring wheat (Triticum aestivum L.). Samples were selected from harvest survey samples submitted by producers from crop districts in Manitoba, Saskatchewan, and Alberta for 1996, 1997, and 1998 crops. The analytical quality control measures used in these surveys are described along with the results for Cd, Cu, Fe, Mn, Se, and Zn. Accuracy and precision for the analyses fell within the acceptable control limits. Year-to-year variations in grain chemistry were small for Cd, Mn, Se, and Zn, but Cu and Fe contents showed 12 and 9% decreases, respectively, over the 3 years. The overall variability for the plant-essential trace elements—Cu, Fe, Mn, and Zn—was low compared with that for Cd and Se. The spatial variation in crop chemistry across the Canadian Prairie wheat-producing region was greater than the year-to-year variations. Soil properties were major factors in controlling Cd and Se levels in grain.

AAC Foray red spring wheat. Can. J. Plant Sci. 95: 799–803. AAC Foray, an orange wheat blossom midge (Sitodiplosis mosellana Géhin) tolerant hard red spring wheat (Triticum aestivum L.), combined high grain yield and good agronomic performance with excellent resistance to leaf and stem rust, and improved resistance to Fusarium head blight. AAC Foray had maturity, straw strength, and test weight similar to the check cultivars. AAC Foray is eligible for grade of the Canada Prairie Spring Red wheat market class.

AAC Elie hard red spring wheat (Triticum aestivum L.) has grain yield and time to maturity within the range of the checks. AAC Elie has an awned spike, a low lodging score indicative of strong straw, and a short plant stature typical of a semidwarf. These traits were comparable to the check Carberry. AAC Elie expressed resistance to prevalent races of leaf and stem rust, and intermediate resistance to fusarium head blight, yellow rust, common bunt, and loose smut. Compared with the five Canada Western Red Spring checks, AAC Elie has improved flour yield, and lower flower ash. AAC Elie is eligible for grades of Canada Western Red Spring.
