Seasonal dynamics of seed dormancy and germination in the weed Diplachne fusca.

ABSTRACT:

Background

Understanding the reproductive biology of weeds is crucial for managing them effectively. Diplachne fusca (Poaceae) is a widely distributed weed species that poses significant challenges to agricultural productivity. Nevertheless, it remains unclear how the soil seed bank of D. fusca responds to environmental shifts, and whether a dormancy cycle is present in this species.

Methods

We investigated how seed dormancy in D. fusca is broken and how it responds to natural environmental changes. The impact of incubation temperature, light exposure, cold stratification at 4 °C, and gibberellic acid (GA₃) on seed germination/dormancy-break was investigated, along with assessing seasonal changes in germinability through monthly excavation and
