“…Thus, the first phase of growth inhibition may be less sensitive to the antagonistic effects of silver. This is consistent with our prior data showing that the first phase of growth inhibition is much less sensitive to 1-MCP (47), a competitive inhibitor of ethylene (55)(56)(57)(58).…”

“…O 1-MCP retarda a senescência de flores cortadas e plantas envasadas quando aplicado em baixíssimas concentrações (Serek et al, 1994Porat et al, 1995;Sisler et al, 1996). Recentes estudos indicaram que o 1-MCP, além de restringir a ação do etileno, pode reduzir sua produção e, com isso, retardar o amadurecimento de muitos frutos climatéricos, como verificado em pêra (Lelièvre et al, 1997b), maçã (Fan et al, 1999), banana (Sisler & Serek, 1997;Jiang et al, 1999), ameixa (Abdi et al, 1998), tomate (Nakatsuka et al, 1997;Sisler & Serek, 1997) e damasco (Fan et al, 2000).…”

O abacate (Persea americana) é um fruto climatérico que apresenta alta taxa respiratória e alta produção de etileno após a colheita, o que o torna altamente perecível. Por isso, o controle do amadurecimento desse fruto é fundamental para o aumento da vida útil de prateleira. Abacates 'Quintal' foram tratados com o bloqueador da ação do etileno 1-metilciclopropeno (1-MCP) nas concentrações de 0, 30, 90 e 270 nL L-1 durante 12 horas a 24ºC e armazenados sob condições ambientais (24ºC) por nove dias. Diariamente foram analisadas as variáveis coloração da casca e polpa, firmeza de polpa, porcentagem de frutos maduros (firmeza <= 8 Newtons), porcentagem de podridões, taxa respiratória e produção de etileno. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 4 x 10, com quatro repetições de quatro frutos. O 1-MCP reteve o desenvolvimento da coloração da casca e polpa e proporcionou maior firmeza de polpa e menor incidência de podridão nos frutos. Frutos não tratados apresentaram início de amadurecimento após quatro dias a 24ºC, enquanto nos frutos tratados com 270 nL L-1 de 1-MCP o amadurecimento iniciou após sete dias. Frutos tratados com 1-MCP (270 nL L-1) apresentaram menor taxa respiratória e menor produção de etileno. Os resultados revelam que a aplicação de 1-MCP em abacates é satisfatória para retardar o amadurecimento dos frutos e aumentar a vida de prateleira.

“…Enhanced leaf expansion rates in F. lyrata have reported using this approach (Jackson et al, 1987;. An closely related measure is to incorporate an inhibitor of ethylene action such as silver nitrate (e.g., Armstrong et al, 1997) or 1-methylcyclopropene, a recently developed and very effective gaseous inhibitor of ethylene action (Sisler et al, 1996) More satisfactory than side-stepping is to introduce an element of convection flow (mass flow) of the air (or water where liquid cultures are uses) to augment the contribution from diffusion alone. With this mechanism of aeration, it is useful to consider the surrounding water or air as a physical carrier of gases to and from the tissue rather than a diffusion medium or barrier.…”

Summary.The requirement for sterility in plant tissue cultures avoidance of dehydration can impose sealing requirements that severely limit the rate of gas exchange in and out of the culture vessel. Conditions within the culture vessel such as the depth of any water cover, the presence of gelling agents, the bulk and porosity of the tissue and the temperature also strongly influence in vitro rates of gas exchange, primarily driven by diffusion. This article uses elements of Fick's Law of Diffusion to identify key factors limiting gas exchange between culture and its immediate surroundings. In particular, it identifies static liquid media, gelling agents, large tissue mass and warm temperatures as imposing severe limits on diffusive flux for gases such as O 2 , CO 2 and ethylene. The principle barrier to diffusive exchange of gases between the in vitro and ex vitro atmospheres is the wall of the enclosing vessel. This is invariably made of glass or plastic that is gas-impermeable and well-sealed against evaporative drying or entry of micro-organisms. Cultures enclosed in this way will, inevitably, asphyxiate unless a compensating pathway for diffusive gas exchange is contrived or replaced by some system of convective flow that carries gases to and from the tissue. Supplementing diffusive aeration with convective flow is the basis of most successful hydroponics systems for whole plants and may be a prerequisite for securing levels of aeration suitable for autotrophic cultures. The paramount consideration is the extent to which the total rate of consumption or production of a particular gas by the cultured tissues is matched by the maximum rates of gas transport imposed by the culture itself, its immediate surroundings and the ventilation and sealing system of the culture enclosure.
