“…2-chloroethyl-trimethylammonium chloride) reduces the length, but does not reduce the weight of the wheat culm. This phenomenon relates to the anatomical effects of retardants, mainly to the simultaneous thickening of the culm and increasing its diameter, while the length of the internodes is shortened (Lowe and Carter, 1972;Sanvicente et al, 1999;Tripathi et al, 2003;Zając 1987). Consequently, straw yield is reduced (Rebetzke et al, 2011).…”

A b s t r a c t. Cereal straw is an important biomass source inEurope. This work assessed: 1) the morphological and energetic characteristics of culms of spring and winter cereals, 2) the energy deposited in the different aboveground parts of cereals, 3) losses of energy due to different cutting heights. The straw of winter and spring cereals was collected from arable fields during the seasons 2009/10 and 2010/11 in southern Poland. Detailed biometric measurements of culms and internodes were performed. The losses of straw biomass and energy were assessed during simulation of cutting the culm at different heights, up to 50 cm. Longer and heavier culms were developed by winter wheat and triticale and oat. Cutting of straw up to 10 cm did not lead to significant losses in straw yield. The total amount of energy in the culms was as follows: triticale > winter wheat > oat > spring wheat > winter barley > spring barley. Cutting the culms above 20 cm led to significant differences in terms of biomass energy between cereal species. The smallest losses of energy were recorded for spring and winter barley. Oat and barley accumulated the highest energy in grains.

“…Applications of growth inhibitors to tomatoes (Abdalla and Verkerk, 1970), which are known to respond to high night temperatures by rapid stem elongation (Went, 1941), were less effective In inhibiting stem growth at higher temperatures than at lower temperatures. A similar response was noted with wheat (Lowe and Carter, 1972). These results sug gest that at higher temperatures GA production or turnover, or the sensi tivity of the plant to GA, was greater than at lower temperatures.…”

“…(2006). This decrease has been linked to an increased sink capacity and an increase in competition between potential grain sites in wheat crops by Lowe and Carter (1972) and Green et al . (1985) noted that chlormequat application reduced the rate of grain growth in the post anthesis period and instead caused redistribution of post anthesis assimilate into non-reproductive organs.…”

Factorial experiments were carried out on spring- and winter-sown oat crops in Ireland in 2016–2019 to identify plant responses in yield formation and grain filling procedures. Two cultivars (Husky and Keely), three seed rates (250, 350 and 450 seeds/m2), six applied nitrogen (N) rates (40, 70, 100, 130, 160 and 190 kg N/ha) with a plant growth regulator (PGR) were examined in spring and winter sowings, using the same cultivars at five rates of applied N (80, 110, 140, 170 and 200 kg N/ha). The applied N rate and seed rate significantly (P < 0.05) modified the yield components determining grains/m2 in spring- and winter-sown crops with increases in panicle number of key importance. Increases were also observed in the proportion of primary grain by weight (0.9–1.6%) and number (0.7–1.4%) ratios in spring-sown crops in response to applied N rate, with winter-sown crops exhibiting a more consistent pattern of grain fill. Seed rate and PGR application had minor effects on yield components and panicle conformation. Grain fill procedures played an important role in the maximization of grain yield under seasonal conditions. Significant positive correlations were observed between the number of aborted grain sites and yield under drought conditions (0.22), with negative associations observed in near-optimal conditions (−0.22 to −0.41). Agronomic effects on grain site abortion were minimal in comparison with seasonal effects. In seasons characterized by cool, consistent conditions, grain yield was maximized by the utilization of all available grain sites. Where assimilate shortages were encountered during grain fill the abortion of grains sites was positively associated with grain yield.
