Aquaporins and the control of the water status in coffee plants [PDF]

Theoretical and Experimental Plant Physiology, 2013
Six aquaporin (AQP) homologues were identified in three coffee species (Coffea arabica, C. Canephora, and C. racemosa), including four plasma membrane intrinsic proteins (PIP1;1, PIP1;2, PIP2;1, and PIP2;2) and two tonoplast intrinsic proteins (TIP1;1 and TIP1;2). In order to better understand the role of these genes in coffee, C.

Sap flow index as an indicator of plant water status [PDF]

Tree Physiology, 1999
Night and especially predawn tree water status is an important indicator of drought stress in trees. Leaf water potential (LWP) is frequently used as a measure of tree water status and hence drought stress; however, there are difficulties associated with sampling foliage from tall trees and determining LWP automatically.

Midday measurements of leaf water potential and stomatal conductance are highly correlated with daily water use of Thompson Seedless grapevines

, 2011
A study was conducted to determine the relationship between midday measurements of vine water status and daily water use of grapevines measured with a weighing lysimeter. Water applications to the vines were terminated on August 24th for 9 days and again

Spatio-temporal dynamics of root water uptake and identification of soil moisture thresholds for precision irrigation in a Mediterranean yellow-fleshed kiwifruit orchard

Frontiers in Plant Science
IntroductionActinidia is highly susceptible to water stress, both excess and shortage, and is therefore a model fruit crop for irrigation management, requiring precise water application.

Online-monitoring of Plant Water Statues Using the Leaf Patch Clamp Pressure Probe: A review

Guan'gai paishui xuebao, 2022
Precision irrigation relies on accurate perception of plant water statue. Plant-based sensors is a potential method to online monitor change in plant water statues due to its convenience , automaton and being able to measure water in both leaf stomata ...

Combining machine learning algorithm and multi-temporal temperature indices to estimate the water status of rice

Agricultural Water Management, 2023
Real-timely monitoring of the crop water status can improve irrigation scheduling to increase water saving and enhance agricultural sustainability, whereas the canopy temperature measured by thermal imaging is an essential indicator for determining the ...

Measurement of Energy Status of Water in Plants With a Thermocouple Psychrometer [PDF]

Plant Physiology, 1962
The thermocouple psychrometer developed by Richards and Ogata (1) measures the relative vapor pressure of water in air near saturation with great precision. Measurement depends on a temperature difference between wet and dry junctions of a sensitive thermocouple. Richards and Ogata (2) used the thermocouple psychrometer to measure the relative pressure

Soybean plant metabolism under water deficit and xenobiotic and antioxidant agent application. [PDF]

, 2020
The aim was to evaluate the interactive eects on biochemistry and physiology of soybean plants exposed to simultaneous xenobiotic and water deficit stresses, and the possible attenuation of plant damage by an antioxidant agent.
