Abstract
Ethephon (2-chloroethyl phosphonic acid) application after heading may enhance the grain yield of cereal crops such as barley (Hordeum vulgare L.) and wheat (Triticum aestivum L.) by altering grain-filling processes. The objective of this study was to evaluate the effects of post-anthesis (1 wk after heading) ethephon application on variables contributing to the grain yield of spring barley cultivars. A field experiment, with application of ethephon at three rates (0, 240, and 480 ga.i.ha −1 ) to two barley cultivars, Cadette and Leger, was conducted on Bearbrook clay soil (fine, mixed, nonacid, mesic Humaquept) in Quebec, Canada in 1988, 1989, 1990 (...)
