Abstract
Anatomical and histochemical studies on phagocytosis were carried out with the juvenile portion (digestion was in an early stage) and the mature portion (digestion was in a late stage) of the wild rhizome of Cymbidium goeringii REICHB. f. Using PAS reaction and ruthenium red method, it was detected that the positive substance with PAS reaction in fungal clot was mainly pectin-like substances. The results with ninhydrin-Schiff′s reaction and azure B method suggested that protein and RNA of fungi were gradually decomposed in the course of content in host- and digestion-cells were indicated by the result with Feulgen method. The significance of phagocytosis in the transference of nitrogenous compounds was discussed in connection with the organogenesis of this orchid.
