Seed banking is a vital component of the integrated strategies required to conserve biodiversity and restore degraded landscapes. The effectiveness of seed banking for Australian flora is limited by a lack of research into the factors affecting seed viability during storage. For key indicative Australian species this study will focus on morphological, biophysical and biochemical factors governing seed longevity to determine the optimum storage conditions and identify bio-indicators of seed deterioration for rapid determination of seed storage behaviour. This project will develop benchmark standards by which the estimated 325 seed banks storing native seeds in Australia will benefit.

种子库是保护生物多样性和恢复退化景观所需综合战略的一个重要组成部分。澳大利亚植物群种子库的有效性是有限的，缺乏研究的因素，影响种子在存储过程中的生活力。对于关键的指示性澳大利亚物种，这项研究将集中在形态，生物物理和生物化学因素的种子寿命，以确定最佳的储存条件和确定种子变质的生物指标，快速确定种子储存行为。该项目将制定基准标准，据估计，澳大利亚325个储存本地种子的种子库将从中受益。
