“…The seed shattering phenology of weeds has attracted much attention because it determines the efficacy of harvest weed seed control (HWSC) at crop harvest [ 10 , 11 , 12 ]. The time of seed release is regulated by complex physiological and genetic mechanisms in conjunction with environmental factors [ 10 ].…”

Seed release is crucial in the reproductive cycle of many desert plant species, but their responses to precipitation changes are still unclear. To clarify the response patterns, we conducted a long-term in situ water addition experiment with five treatments, including natural precipitation (control) plus an extra 25%, 50%, 75%, and 100% of the local mean annual precipitation (145 mm), in a temperate desert in northwestern China. Both the onset and end of the seed release phenophase of the locally dominant shrub, Nitraria tangutorum, were observed from 2012 to 2018. The results showed that both the onset and end time of seed release, especially the end time, were significantly affected by water addition treatment. On average, the end time of seed release was advanced by 3.9 d, 7.3 d, 10.8 d, and 3.8 d under +25%, +50%, +75%, and +100% water addition treatments, respectively, over the seven-year study, compared with the control. The changes in the onset time were relatively small (only several hours), and the duration of seed release was shortened by 4.0 d, 7.5 d, 10.8 d, and 2.0 d under +25%, +50%, +75%, and +100% water addition treatments, respectively. The onset and end time of seed release varied greatly between the years. Preceding fruit ripening and summer temperature jointly regulated the inter-annual variation of the onset time of seed release, while the cumulative summer precipitation played a key role in driving the inter-annual variation of the end time. The annual mean temperature controlled the inter-annual variation of the seed release duration, and these interactions were all non-linear.

"One impact mill commonly used in commercial production in Australia is known as the Seed Terminator[trademark]. Independent research has shown the Seed Terminator[trademark] to be an effective HWSC tool in Australian grain production systems (Anonymous 2017). There is currently little to no published research on the ability of impact mills to destroy weed seed in United States soybean production systems. Therefore, the objectives of this component of this research are to: 1) quantify header loss of weed seed during soybean harvest, 2) determine the effectiveness of the Seed Terminator[trademark] at destroying weed seed and reducing weed seedbanks following soybean harvest, and 3) determine the effects of the Seed Terminator[trademark] on combine performance."--Justification, page 3.
