  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.

Many measurements of the daily changes of photosynthesis for two soybean cultivars indicated that the daily changes of photosynthetic rate (A) exhibited double-peak curve, stomatal resistance turned out contrary to A, and intercellular CO2 concentration (Ci) was decresed lightly in the midday. The inner cause of the midday depression included stomatal factors and nonstomatal factors. The increasing of photon flow density (PPFD) and air temperature (Ta), and the decreasing of relative humunity (RH) caused the...

Net photosynthesis rate, transpiration rate, stomatal conductance of the flag leaf of wheat at booting stage were reduced by moderate soil drought, leaf tempera2 ture was enhanced. Rewatering could make each parameter recovered, and photosynthetic characteristics, were even higher than those of prestressed levels, but the last grain yield was still lowered by drought. The local aged cultivar, Zhu shimai, could keep its stomatal aperture wider, and the concentration of intercellular carbon dioxide is stabler than Yunmai 29 during the period of drought. Stomatal conductance of Zhu shimai recovered rapidily after rewatering. The moderate soil drought appeares to have no aftereffect on the photosynthesis rate, transpiration rate of Zhu shimai, but does have on those of Yunmai 29.
