Changes of Photosynthetic Behaviors in Kappaphycus alvarezii Infected by Epiphyte
Epiphytes on the K. alvarezii. (a) Epiphytes on the surface of K. alvarezii. (b) Epiphyte on the transverse section of K. alvarezii and a single primary rhizoid penetrate through the outer cortical cells to inner cortical cells. (c) Epiphyte on the transverse section of K. alvarezii and a tuft of secondary rhizoids that are cut off from the pericentral cells of lower segments, (d) tetrasporangial branches of epiphyte, (e) broadly ovoid cystocarp of epiphyte, and (f) spermatangial branches of epiphyte.
