A New Laboratory Research Project in Floral Biology for Undergraduate Plant Physiology Students.
We have developed a new research project in floral biology for undergraduate plant physiology students. Lilies are one example of ornamental flowers that have a very short shelf life and can be quite expensive. Attempting to increase the life span of lilies would help increase their post harvest quality and longevity. We analyzed the effects of various plant hormones, e.g. cytokinin (6-benzylamino purine, BAP), epibrassinolide (epiBL), gibberellin (GA3), auxin (IAA), thiadiazuron (TDZ) and abscisic acid (ABA) on senescence and longevity of cut flowers of the Oriental hybrid lily (Lilium spp.) cultivar Sorbonne. In addition, we investigated the effects of ethephon (2-chloroethylphosphonic acid), an ethylene-producing compound and ethylene inhibitors, aminooxyacetic acid (AOA) and silver nitrate (AgNO3) on senescence and abscission of cut lily flowers. Ethephon induced a rapid senescence and abscission of tepals of cut lily flowers. BAP alone or in combination with epiBL delayed senescence of cut lily flowers. The precise role of these plant hormones and inhibitors in senescence and longevity of cut lily flowers will be discussed.
