Abstract: The main epicotyledonary axis in Pisum sativum exhibits a very fluctuating either left- or right-handed deflexion of its first-order laterals, but the biserial buds on the laterals of various further order reveal in this respect certain regularities according to their position on the seedling, their deflexion being very often adaxial in the vicinity of cotyledons, however, in more distant and therefore later produced laterals, as a rule, abaxial. The integrant characteristics of these relationships may become clear from their experimental shift with the aid of exogenous auxin increasing inhibitions as well as of triiodobenzoic acid blocking the transport of endogenous auxin participant also in these embryonic-growth correlations. |
