蓬帕杜石斛的花在授粉后花瓣和萼片过早衰老。授粉引起乙烯期，并伴有较小的呼吸期，膨大，花或花序鲜重和吸水量增加。授粉不影响花瓣和萼片花青素含量和离子泄漏量，也不影响唇部、花瓣和萼片的鲜重和干重。授粉后柱头（柱）和花梗的鲜重和干重显著增加。完整花瓣和萼片的授粉兰花的子房生长大于无花瓣和萼片的授粉兰花，但两者的吸水量差异不显著。
Flowers of Dendrobium 'Pompadour' developed premature petal and sepal senescence following pollination. Pollination induced an ethylene climacteric accompanied by a small respiratory climacteric, epinasty and increased flower or inflorescence fresh weight and water uptake. Pollination did not alter petal and sepal anthocyanin content and ion leakage, and lip, petal and sepal fresh weight and dry weight. The fresh weight and dry weight of stigmas (columns) together with pedicels increased significantly after pollination. Ovary growth of pollinated orchid flowers with petals and sepals intact was greater than that of pollinated orchid flowers without petals and sepals, while their water uptake was not significantly different.
