摘要：

A comparative study of nodulation and callusing in seven (Pisum sativum) varieties has been carried out. The nodulation was characterized by number of nodules and their mass per plant. The frequency of various weight nodules was described by the Lorentz equation. Growth of callus was described using an S-shaped dependent equation. It was shown that plants can produce a maximal (optimum for nitrogen fixation) mass of nodules via an increase in either the nodule number or each nodule mass. This feature is specific to the pea variety. It was also found that the varieties the plants of which have a large number of nodules produce calluses of maximum size. Small calluses are characteristic for varieties having plants with a small amount of large nodules. The data we obtained are interpreted on the assumption that both differentiation and proliferation underlie the nodulation, whereas callusing is based only on the proliferation process. © 2013 Pleiades Publishing, Ltd.
