Příklady transpiration

• Reducing radiation levels by 70% with a hessian cloth only cut transpiration by individual trees by about 10% compared with unshaded plants.

• Evidence presented above decreases the likelihood that alterations in canopy processes such as photosynthesis and transpiration are responsible for these changes at the forest edge.

• In principle, gt was computed as the ratio between transpiration rate and the water vapour concentration difference between the leaf interior and the outside air.

• In other words, do plants that limit transpiration by having lower stomatal conductance exhibit less negative cleaf ?

• The material of the bags did not interfere with transpiration and photosynthesis.

• We also observed substantial night-time transpiration (positive sap flow during the night).

• The 24-h integrated values of sap flow were considered as representative of the daily transpiration of each plant.

• Transpiration rates would then have been increased without corresponding increases in dry matter production.

• A portable system for measuring the photosynthesis and transpiration of graminaceous leaves.

• No attempt was made to distinguish between soil evaporation and crop transpiration.

• Another bene®cial microclimatic change is the reduction in wind speed which in-uences transpiration rate.

• These larvae eventually succumbed only during periods of more prolonged arrested transpiration.

• Early reduction of stomatal conductance, leading to extremely low transpiration rates under forest understorey conditions, may allow these seedlings to minimize direct drought damage.

• Any yield dierentials arise from small dierences in the timing of water use and its partitioning between evaporation and transpiration.

• Predicting effects of vegetation changes on transpiration and evapotranspiration.
