Abstract:
The mycelial colonies of Trichoderma viride were grown between two thin cellophane films for exact measurements. The results obtained testify to the fact that in a mature colony the average length of intercalary cells, the average number of intercalary cells in an internode and the average internode length are stable. At this stage of morphogenesis the mean internode length is shown to be equal to the product of the average intercalary cell length and the average number of intercalary cells in an internode. The coefficients of variation of the internode length and the number of intercalary cells in an internode are found to be equal. The length of an intercalary cell and duration of the doubling cycle of an apical cell of T. viride obey the law of Gamma distribution. According to our observations, the Gamma distribution is typical for the length and duration of the doubling cycle of any bacterial cells and cells of any multicellular organisms.
