“…In addition to a higher application rate, a combination of trinexapac ethyl with chlormequat chloride could also lead to an increase in seed yield. Studies by Szczepanek et al (2021) showed a clear effect in creeping red fescue ( Festuca rubra ) seed propagations, but more research is needed to confirm the effect in orchardgrass seed propagation.…”

The propagation and seed multiplication of site‐adapted and drought‐tolerant grass varieties are essential to provide high‐quality forage in temperate grasslands. A field experiment was conducted from 2016–2019 on orchardgrass (Dactylis glomerata L.) in the province of Styria, Austria. Treatment effects of sulfur, fungicide application and a plant growth regulator, singly and in combination, on seed yield and its reproduction parameters were tested under two different fertilizer nitrogen management systems (single application [N1] and split application [N2]). In terms of seed yield, a combination of all treatments compared to fertilization‐only treatment showed a significant increase of 22% under N2 fertilization. In terms of the thousand seed weight, the fungicide treatments and a combination of all treatments performed significantly better than other treatments within N1 and N2. The use of fungicide and a combination of all treatments also significantly increased the germination capacity in N1. Therefore, a combination of all plant protection treatments is recommended to optimize seed yield, thousand seed weight and germination capacity.

Strong creeping red fescue (Festuca rubra L. spp. rubra Gaudin) is a cool‐season perennial turfgrass widely used in temperate and subalpine regions around the globe. Although creeping red fescue turf is tolerant of shade, low fertility acidic soils, and drought conditions, creeping red fescue seed crops grown in optimal growing environments can lodge, ultimately reducing yield in regions where this important turfgrass is grown for seed. To address this issue, we investigated the effects of two plant growth regulators (PGRs), chlormequat chloride (CCC) and trinexapac‐ethyl (TE), on plant height, lodging, and seed yield of strong creeping red fescue over 9 site‐years in the Peace River region of western Canada. The study encompassed 6 site‐years with first‐year stands and 3 site‐years with second‐year stands. The PGRs were applied alone and in a TE + CCC mixture at the two‐node (BBCH 32–33, where BBCH is Biologische Bundesanstalt, Bundessortenamt and Chemische Industrie) and early head emergence (BBCH 51–52) growth stages in first‐ and second‐year stands, respectively. The application of TE, CCC, and their mixture resulted in a differential decrease in lodging and an increase in seed yield in first‐year stands. However, PGRs applied at BBCH 51–52 on second‐year stands had no effect on seed yield but reduced plant height and lodging. This study found a negative correlation between seed yield and lodging. Among the PGR treatments, the CCC + TE mixture was the most effective in reducing lodging and increasing seed yield of strong creeping red fescue.
