“…Bazzo et al (2019), observed that trinexapac-ethyl caused a reduction in TGW in oat. Martins et al (2021), in studies on the effects of TE in upland rice cultivars, verified that doses above 75 g ha -1 cause a reduction in the thousand grain weight, associated with the application period. Kaspary et al (2015) reported that the use of 150 g of TE ha -1 interfered in the thousand grain weight of white oat cultivars.…”

“…Marco Junior et al (2013), working with different wheat doses and cultivars, concluded that trinexapac-ethyl increases the number of panicles per unit area and wheat yield at doses 75 g ha -1 and 150 g ha -1 . On the other hand, Martins et al (2021) studying the effect of TE application, reported a reduction in yield in rice harvest from the dose of 75 g ha -1 . However, for wheat, TE may positively affect the yield variable, increasing it or not, reducing it in relation to controls (Knott et al, 2016;Swoish et al, 2021).…”

The growth and yield performance of white oat cultivars may vary in response to doses of trinexapac-ethyl (TE) growth regulator. The objective of the work was to evaluate the lodging and productive performance of white oat cultivars under different doses of trinexapac-ethyl growth regulator. The experiments were carried out in a randomized complete block design with four replications, in a 4 x 2 factorial scheme, with four doses of trinexapac-ethyl (0, 50, 100 and 150 g ha -1 ) applied in the phenological stage between the 1 st visible stalk node and the 2 nd perceptible node in two white oat cultivars (URS Altiva and URS Corona). The following were evaluated: plant height, panicle length, panicles per m 2 , spikelets per panicle, grains per spikelet, number of grains per panicle, thousand grain weight, plant lodging and grain yield. The application of trinexapac-ethyl at doses 100 and 150 g ha -1 reduces plant height and panicle components: length, number of spikelets and grains per panicle of the two cultivars. TE doses above 100 g ha -1 provide a significant reduction in lodging with an increase in the number of panicles per m 2 and in grain yield for the two white oat cultivars.

“…Marcos Junior et al (2013), in studying diff erent TE doses and wheat cultivars, concluded that TE increases number of panicles per square meter and grain yield at doses of 75 and 150 g ha −1 . In rice, Martins et al (2021) found that grain yield decreased with application of TE at 75 g ha −1 or higher. In wheat, TE is known to maintain or increase yield compared with control groups (SWOISH; STEINKE, 2017;KNOTT et al, 2016).…”

“…The authors observed that IPR Artemis grown in Mauá da Serra suff ered a reduction in thousand grain weight with TE treatment. Martins et al (2021), in assessing the eff ects of TE on upland rice cultivars, found that doses greater than 75 g ha −1 led to a reduction in thousand grain weight depending on application time. Kaspary et al (2015) reported that the use of 150 g ha −1 TE affected the thousand grain weight of white oat cultivars.…”

This study aimed to assess the effect of different doses and times of application of the growth regulator trinexapac-ethyl on the productive performance of white oat cultivars. The experiment was carried out in Londrina, Paraná State, Brazil, in the 2019 and 2020 seasons using the white oat cultivars IPR Artemis and URS Corona. The experimental design was a randomized block with four replications arranged in a 4 × 3 factorial scheme, conducted separately for each cultivar, with four doses of trinexapac-ethyl (0, 50, 100, and 150 g ha −1 ) and three times of application (T 1 , first node noticeable; T 2 , first node visible and second node noticeable; and T 3 , second node visible and third node noticeable). The following agronomic characters were evaluated: plant height, panicle length, panicles per square meter, spikelets per panicle, grains per spikelet, grains per panicle, thousand grain weight,lodging percentage, and grain yield. Application of trinexapac-ethyl at doses of 100 or 150 g ha −1 at T 2 or T 3 reduced panicle length, spikelets per panicle, and grains per panicle in IPR Artemis and URS Corona. However, it also reduced plant height and increased panicles per square meter and yield in both cultivars. These same doses and times of application resulted in a significant reduction in lodging.

The application of trinexapac-ethyl in white oats, in addition to controlling lodging, can modify the architecture of the plant, which can favor good growth and development and the production of well-formed, large and heavy grains, characteristics that are valued by the food industry oat processing. However, the responses of the white oat genotypes regarding the effect of doses and times of application of the growth reducer can be variable. The objective of this work was to evaluate the effect of different doses and application times of the growth regulator trinexapac-ethyl on the industrial quality of white oat grains. The experiment was carried out with the cultivar IPR Artemis, under a randomized block design with four replications, in a 4 x 3 factorial scheme, corresponding to four doses of trinexapac-ethyl (0, 50, 100 and 150 g ha-1) and three application times (E1: plants with the 1st noticeable node; E2: between the 1st visible node and the 2nd noticeable node and E3: plants with the 2nd visible node and 3rd noticeable node). The weight of one thousand grains, hectoliter weight, percentage of grains with thickness greater than two millimeters, husking index and industrial grain yield were evaluated. The application of trinexapac-ethyl regardless of the stages at doses of 0 and 50 g ha-1 does not interfere with the industrial quality of grains, but at doses of 100 and 150 g ha-1, at times E2 and E3, there is a reduction in industrial quality of grains (weight of a thousand grains, hectoliter weight, percentage of grains thicker than two millimeters, hulling and industrial grain yield) of the cultivar IPR Artemis.
