Fungal attack under light reduces mechanical resistance of the testa of Opuntia seeds, making it easier for the embryo to emerge. However, the effect of fungi on Opuntia seed germination in darkness is unknown. We evaluated the combined effects of light and inoculation with Phoma medicaginis , Trich...
