Heat increases germination of water-permeable seeds of obligate-seeding Darwinia species (Myrtaceae)
We examined the response of seeds to heat in four geographically restricted and one widespread species of shrubby Darwinia from the fire-prone region of southeastern Australia. These shrubs are killed by fire and rely on seed germination after a fire to maintain populations. We…
