摘要：

Pollination stimulated ethylene production concomitant with the increase in ovary growth of Dendrobium 'Pompadour'. Emasculation stimulated ethylene production but did not increase ovary growth. Emasculation synergistically increased ovary growth of pollinated orchid flowers. 1-Aminocyclopropane-1-carboxylic acid (ACC) and 1-naphthylacetic acid (NAA) treatments stimulated ethylene production of orchid flowers but only NAA fully substituted for pollination in enhancing ovary growth, while ACC application synergistically increased ovary growth of pollinated orchid flowers. Aminooxyacetic acid (AOA) treatment inhibited pollination- and NAA-induced ovary growth. ACC application restored the ovary growth response with added AOA prior to pollination. The results suggested that ethylene was required for initial growth of the ovary following pollination in Dendrobium 'Pompadour'.
