Graphical tridimensional extrapolation of the predictive models, generated for each output and genotype, by FormRules^®: (A–E) results for Bryophyllum × houghtonii (BH); (F–J) results for Bryophyllum daigremontianum (BD); (K–O) results for Bryophyllum tubiflorum (BT); (A,F,K) refer to percentage direct shoot regeneration (%DS); (B,G,L) refer to percentage indirect shoot regeneration (%IS); (C,H,M) refer to number of direct shoots (NDS); (D,I,N) refer to number of indirect shoots (NIS); (E,J,O) refer to percentage of callus formation (%CAL). BAP and IAA concentrations are expressed as mg L⁻¹.
