leaf temperature
When soil water is sufficient, the main factors affecting Tr were relative humidity (RH), air temperature (Ta) and leaf temperature (Tl) in July, August and October respectively.
      
The registered indices comprised leaf temperature, leaf transpiration conductivity, and the average daily increment of the leaf area.
      
The drought duration did not affect the adaptation of leaf water balance, it was determined only by leaf temperature and water supply.
      
The authors conclude that water supply and leaf temperature determine plant resistance to soil drought.
      
Measurements of leaf temperature and the vapour pressure gradient between the leaf and the air indicated that leaf surface water originates from the plant.
      
Gas exchange was strongly influenced by photosynthetic photon flux density (PPFD), leaf temperature and the accompanying leaf to air vapour pressure deficit (Δ w).
      
The relationships between leaf net photosynthetic rate of C3 and C4 plant with CO2 concentration intercellular, leaf temperature, and photosynthetic active radiation (PAR) were presented, respectively.
      
It describes the changes in the daily course of transpiration, stomatal behaviour, leaf water potential and leaf temperature as water deficits develop.
      
Significance of leaf orientation for leaf temperature in an amazonian sclerophyll vegetation
      
The influence of leaf orientation on leaf temperature has been studied in an sclerophyll vegetation of the Amazon basin, which grows on white sandy soils of very low water retention capacity and variable depth of the water table.
      
Plant water potential, osmotic potential, stomatal resistance, leaf temperature, soil temperature, height, dry weight, and nutrient composition of winter wheat (Triticum aestivum L.
      
Under uniformly cloudy skies, plant temperatures did not deviate far from air temperatures.3.Under typically fluctuating alpine conditions, correlations between leaf temperature and certain environmental factors are imperfect.
      
The measurement of transpiration and leaf temperature indicated that latent heat loss was much more important in wheat, and sensible heat loss was more important in sorghum as means of dissipating excess energy absorbed.
      
It causes speedier closure of the stomates, as measured by changes in leaf temperature.
      
The degree of stomatal opening has been calculated from leaf temperature, air humidity and wind speed.
      
The effect of leaf temperature, O2 and calculated O2/CO2 solubility ratio in the leaf on the quantum yield of photosynthesis was studied for the C4 species, Zea mays L., and the C3 species, Triticum aestivum L.
      
aestivum and as leaf temperature increased, the quantum yield decreased from 0.062 at 15°C to 0.046 mol CO2 mol-1 quanta absorbed at 35°C.
      
Thus, the decrease in quantum yield with increasing leaf temperature in C3 species may be largely caused by a temperaturedependent change in the solubility ratio of O2/CO2.
      
Alteration of leaf temperature produced anti-parallel changes in induction characteristics of Fc and F680.
      
The underlying causes of this water-stress-induced susceptibility to photoinhibition are unknown; stomatal closure or elevated leaf temperature cannot explain the increased susceptibility.
