Ethylene production by young Aranda orchid flowers and buds

Respiration of isolated Aranda orchid petal cells increased markedly after cut flowers were treated with ethylene . An increase in respiration was observed 15 to 20 h after treatment which was further enhanced in the presence of oxygen and ethylene . Ethylene induces the development of a cyanide resistant pathway in fully opened orchid flower tissues where the cyanide resistant capacity is negligible . However, there appears a shift back to the cyanide sensitive pathway some time after induction .

Research involving plant growth regulators (PGRs) and orchids in areas of orchid growth and development are reviewed . For all areas covered in the review -seed germination and seedling growth, lateral shoot production, root production, flower initiation and development, postharvest physiology, and photosynthate partitioning -it was concluded that further studies would assist in clarifying potential uses for PGRs in the orchid cut-flower industry . It is suggested that extra PGR research on orchids is justified at the present time because of favourable prospects facing the orchid cut-flower industry .
