| 中文摘要: |
| 显型原质团是绒泡菌目黏菌的营养生长阶段，其最明显的现象是往返原生质流，但一直并不清楚原生质流反向流动的原因。观察研究了淡黄绒泡菌和全白绒泡菌原质团中的原生质流，结果表明：由于菌脉中堵塞或是在原质团前缘尚未分化通道引起反向原生质流，从而引起原质团多方向生长使原质团前缘呈现扇面状。原生质流总的方向是扇面端，并完成原质团运动。 |
| 英文摘要: |
| Phaneroplasmodium is assimilative stage in life cycle of Physarales. One of the conspicuous phenomenon in plasmodium is reversible streaming. However, the cause leading to reversible protoplasm streams has been not sure. In this study, the protoplasm streams in the plasmodium of Physarum melleum and P. globuliferum were observed. It was found that the reversible protoplasm stream was caused by clogging in channel of net-veins or undifferentiation channel in the margin of plasmodium. The gross afflux orientation of protoplasmic streaming was fan-shaped and induced the movement of plasmodium. |
