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 to the stigma cause accumulation of 32 P in gynostemia (columns) and ovaries. Translocation characteristics correlate with vascular anatomy of Cymbidium flowers.
