Gonçalo R. R., de Souza Palma R. M., Gonzaga D. R., de Almeida O. J. G., Kolb R. M., Higher temperatures and lower osmotic potentials negatively impact Rhipsalis Gaertn. (Rhipsalideae, Cactaceae) germination and seedling survival, Plant Ecology, 2026, 227(1):5, doi: 10.1007/s11258-025-01581-3
Separate experiments tested eight Rhipsalis species at five constant temperatures and at osmotic potentials reduced with PEG 6000. Moderate temperatures generally favoured germination, while reduced water availability inhibited it and altered seedling survival. Transfers back to favourable conditions revealed species-dependent recovery of germination.
