Cytological Effects of MH-30 on the Growth of Buds in the Tea Plant.

[摘要] The tea buds were sprayded with MH-30 Solution (0.05, 0.1, and 0.3%) and were investigated cytologically from 4 to 11 days after the treatment. Nuclear division was inhibited, but even during this period buds grew gradually at 21°C. In treated cells chromatin granules were larger than those in the controls in the resting stage. After prophase nuclear threads congealed together (Fig. 2). In metaphase and anaphase large chromatin mass was seen instead of chromosomes, although it seemed to recover around 12∼13 days after the treatment according to the concentration of MH. The cells which completed nuclear division seemed to grow gradnally in spite of MH treatment.
