| Summary, etc |
Se estudio el efecto de la temp. foliar en la conductancia estomatica y en la absorcion neta de CO2 en habichuela, utilizando hojas adheridas deshidratadas (estres hidrico de 25-40 por ciento) u hojas cortadas, tratadas con una solucion de 10(-4)M de AAB en la corriente de transpiracion. La reduccion de la temp. foliar causo apertura estomatica y aumento la absorcion neta de CO2 (que era de casi cero a aprox. 25 grados C) a un nivel identico al de las hojas testigo (sin estres hidrico) a aprox. 15 grados C. El efecto del AAB en el cierre estomatico vario dependiendo de la temp. Probablemente, el AAB es responsable en parte del cierre estomatico de la habichuela sometida a estres hidrico. A temp. foliares inferiores a 15 grados C, la absorcion neta de CO2 ya no fue limitada por el estres hidrico, aun en hojas muy deshidratadas. Esto muestra que las hojas deshidratadas retienen mucha de su capacidad fotosintetica que puede revelarse a concn. normales de CO2 cuando los estomas se abren a bajas temp. A diferencia de las hojas tratadas con AAB, la reduccion de la concn. de O2 de 21 a 1 por ciento de O2 no aumento ni la tasa de absorcion neta de CO2 ni el nivel termico optimo para la fotosintesis de las hojas deshidratadas. La produccion de quantum del flujo de electrones del PSII (medida mediante delta F/FM) fue inferior al nivel de 1 por ciento de O2 que al de 21 por ciento para cada pretratamiento foliar (hojas no deshidratadas, hojas deshidratadas y hojas tratadas con AAB), aun a un rango de temp. en el cual la fotosintesis foliar a una concn. normal de CO2 fue igual en estas 2 concn. de O2. Esto probablemente indica heterogeneidad de la fotosintesis, ya que esta diferencia en el rendimiento de quantum desaparece cuando se utiliza una concn. alta de CO2 durante las mediciones.

| Summary, etc |
The effect of leaf temperature on stomatal conductance and net CO2 uptake was studied on French bean (Phaseolus vulgaris L.) using either dehydrated attached leaves (25-40 percent water deficit) or cut leaves supplied with 10(-4)M abscisic acid (ABA) solution to the transpiration stream. Decreasing leaf temperature caused stomatal opening and increased net CO2 uptake (which was close to zero at around 25 degrees C) to a level identical to that of control leaves (without water deficit) at around 15 degrees C. (i) The ABA effect on stomatal closure was modulated by temperature and, presumably, ABA is at least partly responsible for stomatal closure of french bean submitted to a drought stress. (ii) For leaf temperatures lower than 15 degrees C, net CO2 uptake was no longer limited by water deficit even on very dehydrated leaves. This shows that dehydrated leaves retain a substantial part of their photosynthetic capacity which can be revealed at normal CO2 concentrations when stomata open at low temperature. In constrast to leaves fed with ABA, decreasing the O2 concentration from 21 percent to 1 percent O2 did not increase either the rate of net CO2 uptake or the thermal optimum for photosynthesis of dehydrated leaves. The quantum yield of PSII electron flow (measured by delta F/Fm) was lower in 1 percent O2 than in 21 percent O2 for each leaf pretreatment given (non-dehydrated leaves, dehydrated leaves, and leaves fed with ABA) even within a temperature range in which leaf photosynthesis at normal CO2 concentration was the same in these two O2 concentrations. It is concluded that this probably indicates an heterogeneity of photosynthesis, since this difference in quantum yield disappears when using high CO2 concentrations during measurements. (AS) |
