Research in grain crops has focused on understanding the critical period (CP) for yield formation to develop genetic and agronomic options that minimize stress or resource limitation during this time. While the link between the photothermal quotient (PTQ) in the CP and yield potential is known for wheat, it needs re-evaluation with current genetics and agronomy, and is less explored in barley, especially in high productivity areas.

关键期光热商对谷物产量潜力的影响——小麦和大麦的比较


对粮食作物的研究侧重于了解产量形成的关键期 （CP），以开发遗传和农艺选择，以最大限度地减少在此期间的压力或资源限制。虽然小麦的 CP 中的光热商 （PTQ） 与产量潜力之间的联系是已知的，但它需要用当前的遗传学和农学重新评估，并且在大麦中探索较少，尤其是在高产地区。
