Abstract

Pollination induced an increase in ethylene production concomitantly with ovary growth, epinasty, drooping, changes in venation andfading of the colour of the flowers of Dendrobium ‘Pompadour’. Removal of stigmatic fluid prior to pollination significantly reduced ovarygrowth, while ethylene production, epinasty, drooping, venation and colour of pollinated flowers were not significantly affected. Removalof stigma fluid had no effect on ovary growth of non-pollinated flowers treated with 1-aminocyclopropane-1-carboxylic acid (ACC ), butsignificantly reduced the ovary growth of non-pollinated flowers induced by the application of napthaleneacetic acid (NAA). The effect ofstigmatic fluid on ovary growth of pollinated flowers is discussed.
