Abstract:
Seed dormancy and germination play pivotal roles in the agronomic traits of plants, and the degree of dormancy intuitively affects the yield and quality of crops in agricultural production. Seed priming is a pre-sowing seed treatment that enhances and accelerates germination, leading to improved seedling establishment. Seed priming technologies, which are designed to partially activate germination, while preventing full seed germination, have exerted a profound impact on agricultural production. Conventional seed priming relies on external priming agents, which often yield unstable results. What works for one variety might not be effective for another. Therefore, it is necessary to explore the internal factors within the metabolic pathways that influence seed physiology and germination. This review unveils the underlying mechanisms of seed metabolism and germination, the factors affecting seed dormancy and germination, as well as the current seed priming technologies that can result in stable and better germination.
摘要:
种子休眠和萌发在植物的农艺性状中起着举足轻重的作用,休眠程度直观地影响农业生产中作物的产量和品质。种子引发是一种播种前的种子处理,可增强和加速发芽,导致幼苗生长的改善。种子引发技术,旨在部分激活发芽,同时防止种子充分发芽,对农业生产产生了深远的影响。传统的种子引发依赖于外部引发剂,通常会产生不稳定的结果。对一个品种有效的方法可能对另一个品种无效。因此,有必要探索影响种子生理和发芽的代谢途径中的内部因素。这篇综述揭示了种子代谢和发芽的潜在机制,影响种子休眠和萌发的因素,以及目前的种子引发技术,可以导致稳定和更好的发芽。
