“…This is in agreement with other published data (Porat et al 1995b). MCP can be effective at extremely low concentrations-0.5 ppb in some instances (Sisler et al 1996) so the recommended rate of 150 ppb may be unnecessarily high.…”

A single postharvest application of 1-methylcyclopropene (MCP) was effective in prolonging vaselife of Cymbidium orchids by 6 or 7 days, to c. 19 days. It also prevented repeated applications of ethylene shortening the vaselife of Cymbidium orchids. The anti-ethylene effect of one MCP treatment persisted throughout three successive challenges with ethylene at 5-day intervals. A supra-optimal concentration of MCP (500 ppb) showed no adverse effects. MCP was also effective in protecting Cymbidium orchids against accelerated senescence caused by damage to the pollinia. Individual flowers with damaged pollinia senesced even more rapidly than ethylene-treated intact flowers. In the presence of MCP, flowers with damaged pollinia had a vaselife almost equal to that of undamaged flowers. This is a significant finding for the orchid export industry.

“…It is likely that 1 ml l − 1 was far in excess of that required to saturate the response as based on the results of earlier studies with apples (Fan and Mattheis, 1999), bananas (Golding et al, 1999) and flowers. As little as 25 nl l − 1 effectively prevented ethylene-induced abscission of phlox flowers (Porat et al, 1995), and the 1-MCP binding constant for potted flowering be-…”

1-MCP blocks ethylene-induced petal abscission of Pelargonium peltatum but the effect is transient

Continual exposure to 1.5 ml l − 1 ethylene caused 100% petal abscission within 2 h from detached flowers of Pelargonium peltatum (L.) 'Pink Blizzard' (ivy geranium) harvested just after the stigmatic lobes had separated. When flowering plants were first pretreated for 2 h with 1 ml l − 1 1-MCP, ethylene-induced petal abscission was completely inhibited. However, the effect was transient, since percent abscission increased with time after 1-MCP treatment. Based on percent abscission from detached flowers after a 2-h ethylene exposure, the half-life of 1-MCP activity was about 2, 3 and 6 days after 1-MCP treatment at 25, 20.7, and 12°C, respectively, and there was no evidence for a residual effect after 4 or 5 days at 25 and 20.7°C, respectively. A second application of 1-MCP renewed the inhibitory effect. Following 1-MCP treatment, the force required to separate petals from the flower declined linearly with time. The time until complete loss of the inhibitory effect was strongly temperature dependent, e.g. : 1 day at 25°C versus 3-4 days at 12°C. The usefulness of 1-MCP as a commercial treatment to prevent petal abscission from Pelargoniums will depend on shipping and storage temperature and application frequency.

“…A utilização de inibidores da ação do etileno, no tratamento de flores, geralmente é mais eficaz do que a dos inibidores da síntese, pois bloqueiam o efeito do etileno exógeno presente na atmosfera de armazenamento durante o transporte e a comercialização do produto (PORAT et al, 1995).…”

Influência do etileno e do 1-MCP na senescência e longevidade das inflorescências de esporinha

A aplicação de etileno e do 1-metilciclopropeno (1-MCP) têm efeitos marcantes sobre a abscisão e a longevidade em vaso das inflorescências de esporinha (Consolida ajacis). O etileno acelerou a abscisão das flores em concentrações iguais ou superiores a 1,0 mg L -1 de Ethrel quando pulverizado por duas horas em intervalos de 30 minutos. As concentrações de 100 e 1.000 mg L -1 de Ethrel induziram imediata abscisão das flores, reduzindo a longevidade de 4,4 dias nas flores-controle para 1,8 e 1,2 dias respectivamente. O tratamento com 1-MCP (0,5 g m -3 de SmartFresh TM ) foi eficiente em retardar o início da abscisão das flores, mesmo quando 100 mg L -1 Ethrel foi pulverizado imediatamente após a aplicação do 1-MCP. Flores tratadas exclusivamente com 1-MCP ou tratadas antes do Ethrel tiveram a longevidade estendida em 33% em relação ao controle. Houve redução da eficiência do 1-MCP, em estender a longevidade, se aplicado após a pulverização com Ethrel, comparado com o tratamento de 1-MCP isoladamente ou 1-MCP seguido de Ethrel. Esse efeito demonstra que 1-MCP não foi capaz de bloquear completamente os receptores do etileno.Palavras-chave: abscisão, vida de vaso, Ethrel, SmartFresh TM . ABSTRACT INFLUENCE OF ETHYLENE AND 1-MCP ON SENESCENCE AND LONGEVITY OF CONSOLIDA AJACIS INFLORESCENCESEthylene and 1-methylcyclopropene (1-MCP) had strong influence on the Consolida ajacis flower abscission and longevity. Ethylene was able to induce abscission of the flowers in concentrations equal or above 1,0 mg L -1 Ethrel, when sprayed over two hours at 30 minutes interval. Concentrations of 100 and 1000 mg L -1 Ehtrel induced fast flower abscission, reducing the longevity from 4.4 days on the control flowers to 1.8 and 1.2 days, respectively. Treatment with 1-MCP (0.5 g m -3 SmartFresh TM ) was efficient in delaying the beginning of flower abscission, even when the inflorescences were sprayed with 100 mg L -1 Ethrel just after the 1-MCP treatment. Flowers treated exclusively with 1-MCP had the longevity extended in 33% as compared to the control treatment. Similar results were observed when the flowers were treated with 1-MCP followed by Etrhel. Compared to 1-MCP treatment alone or 1-MCP followed by Ethrel, there was a reduction of flower longevity when 1-MCP was applied after the Ethrel. This effect shows that 1-MCP was not able to completely block all the ethylene receptors, if Ehtrel was applied previously to 1-MCP.
