Seed germination ecology of the annual grass Leptochloa panicea ssp. mucronata and a comparison with L. panicoides and L. fusca


, : Seed germination ecology of the annual grass Leptochloa panicea ssp. mucronata and a comparison with L. panicoides and L. fusca. Acta Oecologica 20(5): 571-577

Leptochloa panicea subsp. mucronata is an annual grass that grows in relatively dry habitats. Requirements for dormancy breaking and germination were determined for seeds of this species and compared with those of two species from wet habitats. Seeds of L. panicea were dormant at maturity in autumn, but when exposed to actual or simulated autumn temperatures (e.g. 20/10 or 15/6 degrees C), they entered conditional dormancy and thus germinated to high percentages in light at 35/20 degrees.
