Abstract
Applications of chlormequat ((2-chloroethyl) trimethylammonium chloride) to field plots of cereals at the 3- to 5-leaf growth stages reduced the height of wheat (Triticum aestivum L.) the most, followed by barley (Hordeum vulgare L.), and oats (Avena sativa L.). Height reductions were cultivar-specific in the three crops. Lodging was temporarily delayed by the use of chlormequat, while disease incidence, seed yields, protein, lignin, and cellulose content of the straw were unchanged. Of 53 barley cultivars treated with chlormequat, 35 showed variable degrees of height reduction with 5 reduced significantly to a maximum of 13.2%; 6 showed no response, while 12 grew taller following treatment. In general, reaction of barley cultivars to chlormequat followed genetic relationships similar to those determined by isozyme patterns.
