Pollination causes increases in FW and DW of Cymbidium ovaries and gynostemia. It also initiates FW losses in perianth segments. Auxin (NAA) applications to the stigma have the same effects except that FW of ovaries decreases. All segments of unpollinated flowers increased in DW, whereas FW variations were minimal. These weight changes reflect the aging and subsequent death and/or redifferentiation and further development of pollinated and/or unpollinated orchid flowers.
