“…Increased yield was derived from increased grains per spike and grain mass, and there was also an improvement in test mass and protein, falling number, and a reduction in pre-harvest sprouting. In barley given excessive N fertilization, application of chlormequatchloride alone did not elicit a response; however, ethephon applied alone or in combination with chlormequatchloride shortened plant height and lodging at one location, but unfortunately also reduced grain yield (Ramburan & Greenfield, 2007b). The ethephon treatments exerted their detrimental effect on yield by decreasing the number of grains per spike and grain mass.…”

“…At the same time, it should be noted that there are little-studied features of gibberellin regulation of germination of seeds and vegetative organs of plants containing as a reserve substance proteins, lipids, inulin and other compounds, but not starch. Synthetic substances retardants that have an antigibberellin mechanism of action are widely used to block the physiological action of gibberellins (Carvalho, At the same time, although retardants lead to significant changes in the ontogenesis of plants, features of their effects on the development of plants under skoto-and photomorphogenesis remain little known (Ramburan, Greenfield, 2007;Matysiak, Kaczmarek, 2013;Wang et al, 2016).…”

“…Yield effects of PGRs have been shown to be year, staging, cultivar, and environment specific Smith 1992a, 1992b). Both positive (Rajala and Peltonen-Sainio 2002;Perrott et al 2018) and negative (Caldwell et al 1988;Simmons et al 1988;Ma and Smith 1991b;Ramburan and Greenfield 2007) effects have been demonstrated for different products in barley. Although the across site-year analysis for PGR effects on lodging was not significant, the variance associated with the interaction between site-year and PGR application was >10% and so lodging by site-years is reported below.…”
