主要结论种子加工技术，如抛光和洗涤，通过有限地去除外层和通过淋洗来提高作物种子的质量。工业加工提供高质量的商业种子包括去除发芽的化学抑制物，这对于生产新鲜的芽苗、实现作物的旺盛生长和田间高产潜力是必不可少的。甜菜是温带农业区的主要糖源，为了提高种子发芽性能和幼苗生长，在种子生产过程中经常要经过几个加工步骤。对未加工和加工(打磨和清洗)的甜菜果实进行了萌发试验和幼苗表型鉴定。从果皮中提取的已知的抑制发芽的溶质在发芽试验中进行了测试，并对它们的渗透压和电导率进行了评估。用UPLC-ESI(+)-MS/MS对种子和果皮组织中的脱落酸(ABA)及其代谢产物进行了定量，并用扫描电子显微镜(SEM)分析了果皮结构的物理变化。研究发现，甜菜果实抛光和洗涤处理对发芽性能和幼苗表型均有正向影响，且两者结合使用时，正向效应更强。扫描电子显微镜显示，抛光的机械作用去除了果皮(果皮)的外部组织(薄壁组织)，保留了内部组织(厚壁组织)不变。抛光和清洗去除了果皮中的萌发抑制物，特别是ABA、ABA代谢物和离子。了解支撑这些加工处理有效性的生物化学是推动商业种子质量进一步创新的关键。
Main conclusionSeed-processing technologies such as polishing and washing enhance crop seed quality by limited removal of the outer layers and by leaching. Combined, this removes chemical compounds that inhibit germination.AbstractIndustrial processing to deliver high-quality commercial seed includes removing chemical inhibitors of germination, and is essential to produce fresh sprouts, achieve vigorous crop establishment, and high yield potential in the field. Sugar beet (Beta vulgarissubsp.vulgarisvar.altissimaDoell.), the main sugar source of the temperate agricultural zone, routinely undergoes several processing steps during seed production to improve germination performance and seedling growth. Germination assays and seedling phenotyping was carried out on unprocessed, and processed (polished and washed) sugar beet fruits. Pericarp-derived solutes, known to inhibit germination, were tested in germination assays and their osmolality and conductivity assessed (ions). Abscisic acid (ABA) and ABA metabolites were quantified in both the true seed and pericarp tissue using UPLC-ESI(+)-MS/MS. Physical changes in the pericarp structures were assessed using scanning electron microscopy (SEM). We found that polishing and washing of the sugar beet fruits both had a positive effect on germination performance and seedling phenotype, and when combined, this positive effect was stronger. The mechanical action of polishing removed the outer pericarp (fruit coat) tissue (parenchyma), leaving the inner tissue (sclerenchyma) unaltered, as revealed by SEM. Polishing as well as washing removed germination inhibitors from the pericarp, specifically, ABA, ABA metabolites, and ions. Understanding the biochemistry underpinning the effectiveness of these processing treatments is key to driving further innovations in commercial seed quality.
