The effect of flooding on the exchange of the volatile C₂-compounds ethanol, acetaldehyde and acetic acid between leaves of Amazonian floodplain tree species and the atmosphere [PDF]

open access: yes, 2008
The effect of root inundation on the leaf emissions of ethanol, acetaldehyde and acetic acid in relation to assimilation and transpiration was investigated with 2–3 years old tree seedlings of four Amazonian floodplain species by applying dynamic cuvette

Use of an infrared thermometer for assessment of plant water stress in neck orange (Citrus reticulata Blanco) [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2006
In general, water stress causes stomatal closure in citrus, and this leads to higher leaf temperature. Recently, it has been reported that infrared thermometry technique can be used for detecting stomatal closure indirectly to assess plant water stress ...

Light distribution on citrus canopy affects physiological parameters and fruiting pattern [PDF]

open access: yes, 1992
Light interception by the orange tree canopy during flower bud differentiation and subsequent flowering and fruit setting has been monitored by continuous data recording from 48 silicon cells distributed in different canopy zones.

Using the TIMS to estimate evapotranspiration from a forest [PDF]

open access: yes
The main goals were: (1) to characterize the evapotranspiration (Et) of two forested watersheds using direct measurement techniques, and (2) to evaluate if remotely sensed surface temperatures could be used to estimate Et from the same watersheds.

Sensitivity to increase in leaf endogenous ABA is responsible for stomatal closure under drought stress in cowpea (Vigna unguiculata (L.) Walp.)

open access: yesPlant Signaling & Behavior
Drought stress is a major environmental factor limiting crop productivity worldwide. Plants respond to drought through various physiological mechanisms, including stomatal closure mediated by abscisic acid (ABA).

Effects of Mesophyll Conductance and Nitrogen Content on Carbon Assimilation During Low-Water Stress in Leaf Lettuce Cultivars

open access: yesHorticulturae
Plants have evolved many mechanisms to acclimate to deficit soil moisture conditions, and breeders can use these mechanisms to develop crops with improved abiotic stress tolerance in irrigated agriculture.

Trade-offs Between Water Transport Capacity and Drought Resistance in Neotropical Canopy Liana and Tree Species [PDF]

open access: yes, 2016
In tropical forest canopies, it is critical for upper shoots to efficiently provide water to leaves for physiological function while safely preventing loss of hydraulic conductivity due to cavitation during periods of soil water deficit or high ...
