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. This is thought to be an adaptive mechanism that minimizes transpiration at high irradiances when the leaves are light-saturated. By comparison, transpiration from sun-ower leaves continued to increase, but at a declining rate, over the same range. Insofar as this extra water contributes to transpiration, the crops in no-till plots have a small advantage. Unusually, there was a time lag before there was a corresponding reduction in transpiration (see below). However, high leaf mass results in high transpiration rates leading to the rapid exhaustion of soil moisture reserves. Regulation of transpiration in coee hedgerows: co-variation of environmental variables and apparent responses of stomata to wind and humidity. Transpiration in grafted plants increased as relative humidity of the air decreased from 08:30 to 11:30 hours. When humans began to clear vegetation in the drainage basin, evapo-transpiration and soil water storage both declined. This corresponded to a drier period of the year and plants reacted by reducing top growth, thus limiting plant transpiration. Evapotranspiration, defined as the water removed from soils by evaporation and plant transpiration, is directly related to yield for most cereals.
