Mini-lysimeters to monitor transpiration and control drought stress : system design and unique applications

  title={Mini-lysimeters to monitor transpiration and control drought stress : system design and unique applications},
  author={J. Chard and M. V. Iersel and B. Bugbee},
Methods for the precise control of drought stress have been a holy grail of plant biology research. Here we describe a five-container growth chamber system and a 16-container greenhouse system, each of which uses load cells to monitor and control the mass of a soil/plant system. The calibration and signal conditioning necessary to quantify transpiration over 10 minute intervals is described. Evaporation can be reduced to less than 1% of the transpiration rate by covering the container surface… Expand

Pozzolan Based 3D Printing Composites: From the Formulation Till the Final Application in the Precision Irrigation Field
The results have shown the possibility of the 3D printing of complex geometric parts as microporous structures or thin films using a composite based on poly lactic acid (PLA) and pozzolan and improves the cohesion between the layers of the part during printing. Expand


It is concluded that null balance lysimetry is a useful approach to simulating drought stress in greenhouse experiments, with specific advantages over other available techniques. Expand
Development of synchronized, autonomous, and self-regulated oscillations in transpiration rate of a whole tomato plant under water stress
Results support the recent finding that an increase in xylem tension triggers hydraulic signals that spread instantaneously via the plant vascular system and control leaf conductance and the regulatory role of synchronized oscillations in WPT rate is discussed. Expand
An overview of models of stomatal conductance at the leaf level.
An up-to-date picture of the g(s) models, from the empirical to the process-based ones, along with their mechanistic or deterministic bases are drawn, focused on models capable to account for multiple environmental influences with emphasis on drought conditions. Expand
Slowly developing drought stress increases photosynthetic acclimation of Catharanthus roseus.
Our understanding of plant responses to drought has improved over the decades. However, the importance of the rate of drought imposition on the response is still poorly understood. To test theExpand

Abstract Efficient, automated irrigation systems, which can irrigate the substrate of potted plants to a desired level and supply those plants with just the amount of water required for normal plantExpand
CropAssist, an automated system for direct measurement of greenhouse tomato growth and water use
A simple and reliable technology to automatically record the growth and water use of indeterminate tomato crops has been developed for use in commercial and research greenhouses. Using pairs of loadExpand
Determination of soil water evaporation and transpiration from energy balance and stem flow measurements
Frequent measurements of soil water evaporation (E) and transpiration (T) are needed to quantify energy and water balances of sparse crops. Field experiments were conducted in Lubbock, TX to examineExpand
Measurement of transpiration and leaf conductance
Measurements of leaf transpiration and calculations of leaf conductance to water vapor are important in almost all investigations of plant water relations. Transpiration is a primary determinant ofExpand
An axenic plant culture system for optimal growth in long-term studies.
This system was designed to study nutrient and water stress effects on root exudates, but is useful for assessing a broad range of plant-microbe-environment interactions. Expand
Automated measurement of canopy stomatal conductance based on infrared temperature
Decreased water uptake closes stomates, which reduces transpiration and increases leaf temperature. The leaf or canopy temperature has long been used to make an empirical estimate of plant waterExpand
