Abstract: 1. Amitosis is of general occurence in different tissues (epidermis, parenchyma, meristematic, and sexual cells) of different organs (root, stem, leaf, and flower) of Allium fistulosum L. 2. The types of Amitosis observed are the following: fission, budding, breaking, endoamitosis and partition. 3. The intercellular migrations of nuclear substances are generally through the passages of plasmodesmata, but the cell wall may dissolve or break open, and the nuclear substances pass through the opening to neighboring cells. 4. Amitosis may occur simultaneously with mitosis, or progress simultaneously with the prophase of mitosis. 5. Differences to stain reaction, affinity to acid and basic dyes of the chromatic substances of the nuclei in different cells in the same root tip, or in different cells in the same locule of pollen sac, or in different nuclei of the same cell, or even in the same nucleus of pollen mother cell, or in different nulcei of pollen grain are observed. Thus the problem of change of acid toward basic affinity to acid and basic dyes of the chromatic substances of old and new nuclei and “Nuclear Renovation” needs further study. 6. Meiois is not normal and the chromosome number observed is variable both in somatic and sexual cells. Is it under the influence of amitosis and intercellular migrations of nuclear substance? Are the phenomena observed contradictory to chromosome theory? The problem needs further study. 7. The nuclear substances of epidermis and guard cells may migrate out of stomata; those of pollen mother cells may migrate to tapetum and empty spaces of pollen sac and those of ripen pollen grain may migrate out, leaving thus empty cell wall degenerated. The notion of intercellular migrations of nuclear substances as a means of translocation of organic material undoubtedly needs further study.
