[Allometry and the original and modified Janoschek growth function. (author's transl)].
After a summary of the author's work on the allometry principle with regard to the original and generalized Bertalanffy and Gompertz functions of organic growth attention is drawn to the analogous topic concerning the Janoschek growth function. At first the Janoschek function is resettled a little as to fit also for starting growth with values unequal to zero. After giving the main characteristics illustrated by graphs the allometric principle is applied to the growth function enforcing a repetition of all derivations due to the changed structure against the growth function proper. Secondly, the increase ansatz is changed with integration now leading to curves of finite growth time. Examples for allometry are added taking up values of recent investigations thus allowing for comparison. Finally an approximation method for the calculation of the inflexion points rounds up the paper.
