Mutual perception among conspecific seeds enhances germination synchrony.

ABSTRACT:

Background

Cooperation among conspecific seeds, which influences germination timing and quantity, can enhance the interspecific competitive ability and environmental adaptability of invasive plants. However, the specific underlying mechanisms require further investigation. This study investigates whether a chemical mechanism of mutual perception exists among seeds of the invasive plant Ambrosia trifida L. and its potential impact on seed germination.

Results

We found that increased seed density and higher concentrations of seed extracts significantly promoted germination rates and reduced germination time in Ambrosia trifida L. seeds. Aggregated seeds germinated earlier and more synchronously than isolated seeds, indicating the presence of seed-to-seed communication mediated
