Short- and long-term stomatal responses to fluctuations in environment in southern European greenhouses

Abstract: Stomatal behaviour in cucumber (Cucumis sativus L.) was analysed and modelled as a function of different greenhouse environmental parameters, under variable summer conditions. Solar radiation was the main regulating factor. During the day, large atmospheric vapour pressure deficit increased transpiration which was followed by a reduction in stomatal aperture, suggesting the presence of a feedback response to water stress. However, stomatal behaviour was more sensitive to high atmospheric vapour pressure defici… Show more

“…within seconds; [9], due to low stomatal conductance, because stomata respond comparatively slowly (i.e. within minutes; [10]). This phenomenon may create both temporary and long-term stress reactions in the plants.…”

“…Van de Sanden y Veen (1992) observaron una disminución de g s del 70% en plántulas de pepino cuando el DPV pasó de 0.2 a 1.4 kPa. Chamont et al (1995) apuntan que el comportamiento estomático en plantas de pepino frente al DPV es más sensible cuando va acompañado de una rápida disminución de la radiación.…”

“…Condiciones de elevado DPV pueden propiciar desequilibrios hídricos en las plantas, cuando la demanda evaporativa del ambiente supera la tasa de absorción del agua por el sistema radicular, una respuesta conservadora de las plantas es el cierre estomático (Tenhunen, et al 1987) especialmente cuando va acompañado de bajos niveles de radiación solar (Bunce, 1981;Chamont, et al 1995), en nuestras condiciones los valores máximos de DPV coincidieron con los máximos de radiación. La media de los valores mínimos se encuentra entre 0.3 y 0.1 kPa, los cuales corresponden al periodo nocturno.…”
