The Effect of Flower Development and Pollination on the Fruit Set of Kalanchoe
, 2014 鵝鑾鼻燈籠草及其變種花朵開放後4天，花柱明顯的伸長並與花藥相互接觸。長壽花'Isabella'於開花當天，花柱已與花冠內下層的花藥相接觸，於花朵開放後1天，花柱已伸出花藥之外。三種親本以人工雜交、人工自交、自交(套袋使其授粉)、開放授粉或除雄後套網處理，結果以人工自交以或開放授粉能得到最多種子，其次為人工雜交授粉，自花授粉處理種子數較少，而以除雄後再套網處理者則未收得任何種子。使用鵝變鼻燈籠草為母本與長壽花'Isabella'雜交時，每朔果中平均收得135顆種子，反交時每朔果中平均收得33粒種子。The
