摘要：

Radioactive phosphate applied to labella (lips, median petals), dorsal (median) sepals or stigmas of Cymbidium cv. ''Jungfrau'' is transported to all parts of the flower. Transport levels vary depending on the sites of application or accumulation. Pollination or application of NAA [naphthalene acetic acid] to the stigma cause accumulation of 32P in gynostemia (columns) and ovaries. Translocation characteristics correlate with vascular anatomy of Cymbidium flowers.
