“…The system of a carrier as suggested hy Lundegardh seems to he satisfactory to apply the energy to accumulation. It is similar in principle, though not in detail, to the one suggested hy Wohl and James (1942). Lundegardh's hypothesis meets a numher of the requirements imposed hy other ohservations.…”

The mechanism of the accumulation of salts in plant cells has been thesubject of much investigation. Lundegardh (1945, 1946, 1947), in restating hishypothesis of salt accumulation, shows how the salt or anion respiration, bycausing transport 'Of anions, could provide a me~hanism of accumulation. It hasbeen shown (Robertson and Wilkins 1947) that the quantitative evidence availableis not inconsistent with this hypothesis. In this paper the hypothesis willbe discussed and the evidence will be given in detail.

“…However, in these studies emphasis has only been on the energy consumption through photosynthesis (GPP, i.e., gross primary production). The fact that heat will also be released during the process of plant respiration (e.g., Wohl and James, 1942;Thornley, 1971) has been neglected in most studies. This had led to an overestimation of the chemical heat storage.…”

Abstract. Land surface–atmosphere interaction is one of the most important characteristic for understanding the terrestrial climate system, as it determines the exchange fluxes of energy and water between the land and the overlying air mass. In several current climate models, it is common practice to use an unphysical approach to close the surface energy balance within the uppermost soil layer with finite thickness and heat capacity. In this study, a different approach is investigated by means of a physically based estimation of the canopy heat storage (SkIn+). Therefore, as a first step, results of an offline simulation of the land component JSBACH of the Max Planck Institute Earth system model (MPI-ESM) – constrained with atmospheric observations – are compared to energy fluxes and water fluxes derived from eddy covariance measurements observed at the CASES-99 field experiment in Kansas, where shallow vegetation prevails. This comparison of energy and evapotranspiration fluxes with observations at the site-level provides an assessment of the model's capacity to correctly reproduce the diurnal cycle. Following this, a global coupled land–atmosphere experiment is performed using an AMIP (Atmospheric Model Intercomparison Project) type simulation over 30 years to evaluate the regional impact of the SkIn+ scheme on a longer timescale, in particular, with respect to the effect of the canopy heat storage. The results of the offline experiment show that SkIn+ leads to a warming during the day and to a cooling at night relative to the old reference scheme, thereby improving the performance in the representation of the modeled surface fluxes on diurnal timescales. In particular: nocturnal heat releases unrealistically destroying the stable boundary layer disappear and phase errors are removed. On the global scale, for regions with no or low vegetation and a pronounced diurnal cycle, the nocturnal cooling prevails due to the fact that stable conditions at night maintain the delayed response in temperature, whereas the daytime turbulent exchange amplifies it. For the tropics and boreal forests as well as high latitudes, the scheme tends to warm the system.

“…the respiratory quotient, but do not contain any direct information on energy. The metabolic heat rate measures respiratory energy loss (Wohl and James 1942), and the ratios of metabolic heat rate to the CO2 and 02 rates are both related to energy-use efficiency, but through somewhat different parameters. The purpose of this paper is to explore the advantages of adding metabolic heat rate to the list of readily available measures of plant respiration.…”

Abstract.A thermodynamic model describing the relation between plant growth and respiration rates is derived from mass-and enthalpy-balance equations. The specific growth rate and the substrate carbon conversion efficiency are described as functions of the metabolic heat rate, the rate of CO2 production, the mean oxidation state of the substrate carbon produced by photosynthesis, and enthalpy changes for conversion of photosynthate to biomass and CO2. The relation of this new model to previous models based only on mass-balance equations is explored. Metabolic heat rate is shown to be a useful additional measure of respiration rates in plant tissues because it leads to a more explicit description of energy relations. Preliminary data on three Zea mays (L.) cultivars are reported. The model suggests new rationales for plant selection, breeding and genetic engineering that could lead to development of plants with more desirable growth rates.
