    Daylength change and leaf appearance in winter wheat (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 3 (1980), S. 0 
    Details
    ISSN: 1365-3040

    Thema: Biologie
    Notizen: Abstract In the field successive leaves of winter wheat appear at a rate which varies because it depends strongly upon temperature. When plotted against ‘thermal time’, however (temperature accumulated above a fixed base of 0°C), leaf appearance was a strictly linear function of temperature. The mean rate of leaf appearance in thermal time, R′, was faster for a spring sowing than for an autumn sowing. The variation in R′ between sowings was better correlated with the rate at which daylength was changing when the plants emerged than with the mean daylength while leaves were appearing.

    A reinterpretation of stomatal responses to humidity (1995)
    Oxford, UK : Blackwell Publishing Ltd
    Plant, cell & environment 18 (1995), S. 0 
    Details

    Thema: Biologie
    Notizen: The stomatal conductance (g) for single leaves and the equivalent canopy conductance for stands of vegetation are often represented in models as empirical functions of saturation vapour pressure deficit or relative humidity. The mechanistic basis of this dependence is very weak. A reanalysis of 52 sets of measurements on 16 species supports the conclusion of Mott & Parkhurst (1991, Plant, Cell and Environment 14, 509–515) that stomata respond to the rate of transpiration (E) rather than to humidity per se. In general, ∂g/∂E is negative and constant so that the relation between g and E can be defined by two parameters: a maximum conductance gm obtained by extrapolation to zero transpiration, and a maximum rate of transpiration Em obtained by extrapolation to zero conductance. Both parameters are shown to be functions of temperature, CO2 concentration, and soil water content. Exceptionally, transpiration rate and conductance may decrease together in very dry air, possibly because of patchy closure of stomata.

    Notizen: [Auszug] Two field balances of the type described by Morris4 were installed in a level 20-acre field at Rothamsted and are distinguished as 'east' and 'west', about 30 and 90 m respectively from the eastern and western boundaries. They are about 180 m from each other and 180 m from the southern boundary. ...

    The exchange of water and carbon by crops in a mediterranean climate (1993)
    Springer
    Irrigation science 14 (1993), S. 85-91 
    Details
    ISSN: 1432-1319
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: Abstract The amount of biomass accumulated by a crop stand per unit of water transpired is referred to as a Biomass Water Ratio (BWR). The paper is mainly concerned with the dependence of BWR on climatic factors, in particular, saturation vapour pressure deficit (D) and precipitation (P) with which D is highly correlated in a mediterranean climate. A method is outlined for estimating the amount of water evaporated from bare soil during the establishment phase of a crop as a fraction of total seasonal water use. A simple model is derived for the BWR as a function of climate and of two stomatal parameters derived from a relation between stomatal conductance and transpiration. Values of BWR are presented for three contrasting stations in Israel and are shown to be strongly correlated with D and therefore with P. The model is combined with an empirical relation between the Priestley-Taylor coefficient and surface resistance in order to establish a new relation between BWR and resistance and to demonstrate that BWR × D is almost independent of resistance above 100 sm−1.

    Notizen: Abstract Daily mean values of the Priestley-Taylor coefficient, α¯, are derived from a simple model of the daily growth of a convective boundary layer. For a particular control set of driving environmental variables, α¯ is related to the prescribed bulk surface resistance, rS by 1/α¯ = 1/α0 + mrS for parameters α0 and m. The dependence of the parameters α0 and m on weather is explored and a potential use of this linear relation to provide information about regional values of rS is indicated.

    Resistance of a partially wet canopy: Whose equation fails? (1977)

    Notizen: Abstract Shuttleworth's analysis of evaporation from partly wet canopies is appropriate only for the unrealistic case of dispersed, minute water droplets. When a more realistic model is used, the predicted range of canopy resistances is consistent with experimental estimates for a pine forest.
