The potent germination stimulant, known as butenolide, is expected to provide substantial benefits for improving seed germination and seedling vigour of many plant species used in agriculture, land restoration and rehabilitation. Currently, little is known about the stability, persistence and distribution of the butenolide in natural environments and the mechanism of seed dormancy breaking. This study now provides a unique opportunity for Australian research to establish a world-leading position in understanding the processes that regulate seed dormancy, particularly in relation to post-mining land rehabilitation. The research findings will also have wider application in plant conservation, weed control and crop production.

被称为丁烯二酰亚胺的强效发芽刺激剂预计将为农业、土地恢复和重建中使用的许多植物物种的种子发芽和幼苗活力提供实质性益处。目前，对丁烯酰草胺在自然环境中的稳定性、持久性、分布以及打破种子休眠的机理还知之甚少。这项研究现在为澳大利亚的研究提供了一个独特的机会，在了解调节种子休眠的过程方面建立世界领先的地位，特别是在采矿后的土地恢复方面。研究成果在植物保护、杂草控制和作物生产方面也将有更广泛的应用。
