刚刚，科学家利用Videometer多光谱成像系统发表了题为“Biochemical and Physical Screening Using Optical Oxygen-Sensing and Multispectral Imaging in Sea Oats Seeds”的文章，使用物理和生化筛选来预测种子质量。

使用光学氧传感和多光谱成像对海燕麦种子进行生化和物理筛选

摘要：物理、生理和生化性状控制着种子的发芽、寿命、持久性和幼苗生长等关键功能。这些性状在物种之间和物种之间是多种多样的，也受到种子起源环境的控制。因此，筛选种子性状并了解它们在种子功能中的作用对于促进资源的经济利用至关重要，用以收集、分类和保存具有农艺和生态重要性的种子材料。我们假设海燕麦种子中存在物理和生化性状，这些性状可以用作预测活力和活力，以在非最佳储存条件下为生存奠定基础。利用多光谱成像和光学氧传感分析，我们评估了从美国大西洋和墨西哥湾海岸线采集的海燕麦种子的物理和生化性状。研究结果表明，有几个性状与海燕麦种子的衰老胁迫存活有关。这些结果证实了使用物理和生化筛选来预测种子质量的潜力，同时为延长种子寿命提供了视角。因此，探索和分析种子的物理和生化特性可以挖掘有助于生存和寿命的明显标记。

Biochemical and Physical Screening Using Optical Oxygen-Sensing and Multispectral Imaging in Sea Oats Seeds

Abstract: Physical, physiological, and biochemical traits control critical seed functions such as germination, longevity, persistence, and seedling establishment. These traits are diverse between and among species, and they are also controlled by the environment in which the seed originated. Therefore, screening seed traits and understanding their roles in seed functions is crucial to facilitate the economical use of resources in collecting, sorting, and conserving seed materials of agronomical and ecological importance. We hypothesized the existence of physical and biochemical traits in sea oats seeds that can be used as proxies to predict viability and vigor to develop underpinnings for survival after non-optimal storage conditions. Using multispectral imaging and optical oxygen sensing analyses, we evaluated the physical and biochemical traits of Uniola paniculata L. (sea oats) seeds collected from the US Atlantic and Gulf coastlines. Our results showed that several traits correlate to aging stress survival in sea oats seeds. These results confirm the potential of using physical and biochemical screening to predict seed quality while offering insights into extended seed longevity periods. Therefore, exploring and analyzing the physical and biochemical properties of seeds could reveal salient markers that contribute to viability and longevity
