| description | BACKGROUND
Lodging can negatively affect yield and quality of barley grain. Synthetic plant growth regulators (PGRs) reduce lodging by producing shorter, thicker, and stronger stems. However, the impact of applying PGRs on malting performance of barley is not known. The objective of this work was to assess the effect of application of three PGRs (ethephon, chlormequat chloride, and trinexapac‐ethyl) in combination with different seeding rates on the malting quality of barley grown in several locations and years in western Canada.
RESULTS
The kernel weight in PGR‐treated barley was reduced by 1.7% to 6.5% compared with the nontreated grain. Application of PGRs had no effect on the concentration of proteins and germination energy. Seeding rates significantly affected kernel weight, protein content, and germination index (GI), but no interactions between PGRs and seeding rates were observed. The smaller kernels of ethephon‑ and trinexapac‐treated barley showed good hydration and grain modification during malting, as indicated by high levels of starch‐converting enzymes, high Kolbach indices, and low levels of wort β‐glucans. Overall, the fine extract of malt from PGR‐treated barley was slightly lower than that of the control malt; however, the extract reduction was statistically significant only for chlormequat‑ and trinexapac‐treated barley.
CONCLUSIONS
The application of PGRs had significant effects on kernel plumpness and kernel weight, but the effects of PGR application on the malting quality were generally small and insignificant. The decision of PGRs application on malting barley needs to be considered in combination with potential benefits of PGRs in mitigating lodging and their effects on the agronomic performance of barley. © Her Majesty the Queen in Right of Canada 2019 |
