Contreras-Quiroz M. D. R., Pando-Moreno M., Flores J., Jurado E., Effects of wetting and drying cycles on the germination of nine species of the Chihuahuan desert, Botanical Sciences, 2016, 94(2):221-228, doi: 10.17129/botsci.457
A comparison of the responses of nine desert species to wetting and drying cycles. In Ferocactus pilosus, three cycles increased germination and shortened t₅₀. The results show variation in responses among the plants studied.
