Stress-induced Ethylene Production in Flower Parts of Cut Carnation Flowers Cv. Light Pink Tasman
Ethylene is a plant hormone with endogenous production associated with the process of senescence for a number of cut flowers. Different stressogenic factors, including signals such as pollination, exogenous ethylene and auxins have been found to be associated with the increase in ethylene emission and a specific tissue response has been documented. The present study was undertaken with the aim ...
متن کاملEthylene-induced gene expression in carnation petals : relationship to autocatalytic ethylene production and senescence.
Exposure of carnation (Dianthus caryophyllus L.) flowers to ethylene evokes the developmental program of petal senescence. The temporal relationship of several aspects of this developmental program following treatment with ethylene was investigated. Exposure of mature, presenescent flowers to 7.5 microliters per liter ethylene for at least 6 hours induced petal in-rolling and premature senescen...
متن کاملReversible inhibition of ethylene action and interruption of petal senescence in carnation flowers by norbornadiene.
The inhibitory effects of the cyclic olefin 2,5-norbornadiene (NBD) on ethylene action were tested in carnation (Dianthus caryophyllus L. cv White Sim) flowers. Treatment of flowers at anthesis with ethylene in the presence of 500 microliters per liter NBD increased the concentration of ethylene required to elicit a response (petal senescence), indicating that NBD behaves as a competitive inhib...
متن کاملبررسی تغییر فعالیت آنزیمی و پرولین در گل‌های گلدانی برخی ارقام میخک مینیاتوری (Dianthus caryophyllus L.) تحت تنش اتیلن
This study was performed to evaluate the role of ethylene stress, ethylene inhibitors and action treatments on longevity of potted-carnation flowers. For this purpose, first, potted-carnation flowers were pretreated with different concentrations of amino-oxyacetic acid (AOA), benzyladenine (BA) and 1-methylcyclopropene (1-MCP). Then, ethephon (as stress treatment) was sprayed on the pretreated ...
متن کاملComparison between Ultraviolet Irradiation and Ethylene Effects on Senescence Parameters in Carnation Flowers.
The effects of ethylene and ultraviolet (UV) irradiation on parameters of senescence in carnation (Dianthus caryophyllus L. cv White Sim) flowers were characterized and compared.UV irradiation (lambda(max) = 254 nanometers), at fluences above 18 kilojoules per square meter, induced petal in-rolling, similar to that which occurred during natural senescence or after ethylene treatment. Increase i...
