Cytochemical studies on the mitotic spindle and the phragmoplast of plant cells

摘要: Abstract 1. In the mitotic spindle and phragmoplast of fixed plant cells, cytochemical tests with staining methods were carried out for pentosenucleic acid, proteins polysaccharides. 2. late prophase, acid is accumulated in polar caps. pollen mother cell Lilium prometaphase meiotic first division, present a fibrous area around chromosome group. 3. The metaphase contains abundant clearly distinguishable from cytoplasmic area. 4. anaphase poleward regions are proved to contain as metaphase; on other hand, interzonal region between separated daughter groups gives reaction almost same degree cytoplasm. difference discussed. 5. rich but plate free it. 6. By acidic dyes combined hydrolysis it was shown that associated caps, phragmoplast. 7. shows presence Polysaccharides already appear at equatorial plane before reaches side wall.
