Aragón L., Lasso E., How do young cacti (seeds and seedlings) from tropical xeric environments cope with extended drought periods?, Journal of Arid Environments, 2018, 154:1-7, doi: 10.1016/j.jaridenv.2018.03.009
An experiment with seeds and one-year-old seedlings of three cacti from Tatacoa. Water potential constrains germination, and drought survival depends on its duration and species.
