Reversible 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 کاملInhibition of ethylene action by 1-methylcyclopropene prolongs storage life of apricots
‘Perfection’ apricot fruit (Prunus armeniaca L.) were treated with 1 ml l 1-methylcyclopropene (MCP) for 4 h at 20°C then stored at 0 or 20°C. The onset of ethylene production was delayed and respiration rate was reduced following MCP treatment. MCP treatment resulted in less firmness and titratable acidity loss during storage at both temperatures and delayed production of volatile alcohols and...
متن کاملControl of ethylene responses in avocado fruit with 1-methylcyclopropene
Mature avocado fruit (Persea americana Mill. cvs ‘Ettinger’, ‘Hass’, ‘Reed’ and ‘Fuerte’), harvested during the commercial harvesting season, were treated with various concentrations of 1-methylcyclopropene (1-MCP) for 24 h at 22°C and after ventilation, were exposed to 300 ml l ethylene for 24 h at 22°C. The fruit were then stored at 22°C in ethylene-free air for ripening assessment. Ethylene ...
متن کاملInteraction of 1-Methylcyclopropene and Thidiazuron on Cut Stock Flowers Vase Life
Leaf yellowing or petal senescence is the main postharvest disorder for many cut flowers. Plant hormones such as cytokinins are able to inhibit leaf yellowing in some cut flowers and potted plants. In our experiments, we applied thidiazuron aiming to delay leaf yellowing and 1-methylciclopropene (1-MCP) for inhibiting flower senescence of cut stock flowers during vase life. Cut flowers were pul...
متن کاملاثر دمای پایین و تیمارهای بازدارنده اتیلن روی فعالیت آنزیم های آنتی اکسیدان و اتیلن تولیدی در میخک مینیاتوری(Dianthus caryophyllus L.)
Senescence is a factor limiting the marketing of most flowers and considerable effort has been applied using various treatments to increase longevity of flowers. Accordingly, a factorial experiment based on completely randomized design with two miniature carnation cultivars (Aragon and Erueka), two temperatures (2 and 4 ° C), 13 treatments (control treatment and various concentrations of amino-...
