大豆种皮裂纹的研究进展

大豆是我国重要的经济作物,大豆种皮在不同的胁迫条件下会开裂形成裂纹。大豆种皮裂纹性状不仅会降低大豆种子的外观表现,还会影响种子的贮藏能力及活力,从而降低了大豆种子的商品价值。尽管人们早已注意到种皮裂纹这一性状,但国内外详细研究这方面的内容并不多。鉴于此,综述了大豆种皮构成、种皮裂纹的特点、引起种皮开裂的因素、裂纹的遗传分析、裂纹检测识别技术以及降低裂纹率措施研究进展,为未来大豆的抗种皮裂纹育种及种子加工贮藏提供可借鉴的理论依据。

Research Progress on Cracks in Soybean Seed Coat

Soybean is an important cash crop in China. The seed coat of soybean will crack under different stress conditions and form cracks. Soybean seed coat crack traits not only reduce the appearance of soybean seeds, but also affect the storage capacity and vigor of seeds, thus reducing the commercial value of soybean seeds.Although people have already noticed the traits of seed coat cracks for a long time, there is not much detail in this area at home and abroad. In view of this, the paper reviewd the research progress of soybean seed coat composition, the characteristics of seed coat cracks, the factors causing of seed coat cracking, the genetic analysis of crack, the crack detection and identification technology, and the research progress of the crack reduction rate, so as to provide a theoretical basis for seed coat crack-resistant breeding and seed processing and storage of soybean for future.
