Enhancing crop yield by increasing planting density has long been a widely accepted agricultural practice. However, high-density planting is prone to problems, such as increased intraspecific competition. Growth regulators are often used to mitigate the challenges posed by heightened intraspecific competition and the negative effects on kernel setting and final yield associated with dense planting. However, the exact mechanisms of these growth regulators in kernel formation remain unclear.

EDAH 促进夏玉米籽粒形成和产量的潜力


长期以来，通过增加种植密度来提高作物产量一直是广泛接受的农业做法。然而，高密度种植容易出现种内竞争增加等问题。生长调节剂通常用于缓解种内竞争加剧带来的挑战以及与密集种植相关的对籽粒坐取和最终产量的负面影响。然而，这些生长调节因子在籽粒形成中的确切机制仍不清楚。
