FIGURE 3. Rhizoidal branch development of Stigeoclonium polyrhizum. A. Zoospore, stained with Lugol's iodine solution; B. One-day- old culture; C. Two-day-old culture, predominantly prostrate zoospore germination; D. Four-day-old culture with obvious rhizoids and delayed development of the erect system; E. Five-day-old culture with rhizoidal branch; F. Six-day-old culture showing many rhizoidal branches; G. Seven-day-old culture; H. Twelve-day-old culture showing profuse rhizoidal branches. Scale bars: A, B = 5 μm, C = 2 μm, D = 10 μm, E = 20 μm, F, G, H = 50 μm. Es: erect system, Ps: prostrate system, Rb: rhizoidal branch, R: rhizoid.
