Understanding seed longevity in weeds

农业系统中有效的杂草管理是实现最大潜在产量和作物质量的关键。然而，杂草种子在土壤种子库中的命运还不是很清楚。每年，土壤库中只有一小部分种子会发芽，但它们在土壤中的存活时间往往比在现代种子库中精心控制的条件下更长。即使在一个物种内，不同的材料/品系在这些特性上也是不同的。这些差异的基础目前尚不清楚，但阻碍了从筛选除草剂到制定适当的农艺措施的强有力的杂草控制战略的发展。

Efficient weed management in agricultural systems is key for achieving maximum potential yields and crop quality. The fate of weed seeds in the soil seedbank though is not well understood. Only a fraction of the seeds in the soil bank will germinate each year, but they often survive for longer in soil than in carefully controlled conditions of a modern seed store. Different accessions/strains vary in these traits even within a species. The basis of these differences is currently unknown but hampers the development of robust weed control strategies, from the screening of herbicides through to the development of appropriate agronomical practices
