Grok says “Wheat grain treated with glyphosate pre-harvest is almost always non-viable for planting. Glyphosate kills the plant’s metabolic processes, making seeds unable to germinate reliably. Farmers use certified, untreated seed instead.”
Thanks. I was applying that question to control of weeds with green seeds, some of which have been remarkably persistent. But with changes wrought by me, such as removing trees or burning weeds and brush, one wonders at the consequent germination. Yes, burning and sunlight do make big differences in dormant seed expression, the karrakinolide hormones in smoke being key.
