Seed dormancy contributes to the persistence of weeds in agriculture by enabling seeds to remain viable in the soil for many years, and is a major reason why annual ryegrass (Lolium rigidum) has become the most economically damaging weed in Australian agriculture. Recently we discovered a new way to control dormancy release and germination in these seeds. This project to identify the changes occurring within the seeds during dormancy release will underpin our efforts to manipulate emergence timing in order to improve the efficacy of current weed control practices and contribute to sustainable farming systems.

种子休眠通过使种子在土壤中保持多年活力而有助于农业中杂草的持续存在，并且是一年生黑麦草（Lolium rigidum）已成为澳大利亚农业中最具经济破坏性的杂草的主要原因。最近，我们发现了一种新的方法来控制这些种子的休眠解除和发芽。这个项目，以确定在休眠释放过程中发生在种子内的变化将支持我们的努力，以操纵出苗时间，以提高目前的杂草控制措施的有效性，并有助于可持续的农业系统。
