Oat varietal response to plant growth regulators
This project will look at the responses of different oat milling varieties to applications ofthe registered plant growth regulators (PGRs) Moddus and Manipulator. Through previous research, both products have been found to decrease plant height, which diminishes the risk of lodging in cereal crops. Lodging has the potential to cause yield losses of 7-35% in cereal crops and can subsequently lead to significant reductions in grain quality. Plant height in oats is often increased with enhanced fertility as more available N results in more rapid plant growth. It is suspected that different varieties will respond differently to PGR applications as a result of different genetics for yield, lodging, and height characteristics.
