Hourly meteorological and soil water potential data collected during the summer season on a container crop of 2-year-old plants of Hypericum hidcote were used to develop a methodology that integrates climate-based (AET=ETo×K c ) and soil-based methods (soil water potential measurements by tensiometers) for the automatic control of the irrigation of plants growing in pots. Hourly ETo values...
In the leaves of herbaceous plants sub-optimal temperatures influence the content and efficiency of the photosynthetic pigments and, in more severe cases, alter mesophyll thickness. This paper examines the possibility of detecting the degree of alteration in sorghum leaf characteristics by indices of stress calculated from remotely sensed data. Reflectance, colorimetric and ecophysiological measurements...
