Guard cells perceive external and internal stimuli and regulate stomatal conductance in plants. With the use of gas exchange analyzers, time-resolved stomatal conductance responses to light intensity,...
A fast and completely automated procedure is proposed for the preparation and determination of d13C of total inorganic carbon dissolved in water ( d13CTDIC). This method is based on the acidification...
Remote sensing and geospatial applications very often require ground truth data to assess outcomes from spatial analyses or environmental models. Those data sets, however, may be difficult to co...
The purpose of the present study was to investigate whether the electrical resistance values of the cervical mucus and/or blood οestradiol-17β and progesterone concentrations at mating, after oestrous...
In each case, one blood sample was collected from all ewes at sponge insertion, at sponge removal and at oestrus, for the determination of serum οestradiol-17β and progesterone concentrations, usi...
The goal of this study was calibration of the ECH20 soil moisture sensor EC-5 and the sensor SM200 for selected soils of the Czech Republic. Based on the soil maps of the Czech Republic and various cl...
Downtowns, the traditional business centers of our communities, have survived many changes throughout the last century. Once thriving retail and civic centers, they were adversely affected by changes ...
The paper describes the system for measuring and logging of data on soil water content and soil temperature profile. The system was tested in a field and shows great potential for performing continuou...
Rainfed smallholder agriculture in semi-arid environments of sub-Saharan Africa faces many challenges. Productivity of the smallholder agricultural systems has been on the decline in recent years. Con...
We have developed a near-infrared (NIR) spectrometer mountable on a head-feeding combine for measuring rice protein in real time while harvesting. The developed sensor employs reflectance optics inst...
Traditional methods of measuring soil organic carbon (SOC) are not adequate for accurate evaluation of C sequestration nor to meet environmental safety requirements. Methods that permit accurate asses...
Increased interest in implementing projects in the Sahel region of Africa for sequestration of atmospheric carbon dioxide in soil organic matter has intensified the need for methods that accurately me...
This study was conducted in the Department of Home Economics, Government College University, Faisalabad, Pakistan during 2007-08. The main objective was to investigate and carry out the situational an...
Portable Equipment for Measuring Three Dimensional Information of Crop Canopy Using a Magnetic Field Sensor.
Root branching in maize (Zea mays L. cv. Pioneer 3558) at harvest stage was examined, with the "branching index" defined as the product of the 'length factor' and 'density factor'. "Branching index" w...
