Water status diagnosis in greenhouse drip-irrigated tomato and celery using leaf turgor dynamics and machine learning

open access: yesFrontiers in Plant Science
IntroductionAccurate crop water status monitoring is crucial for optimized irrigation in controlled environments, but traditional approaches relying on damaging measurements or sporadic sampling frequently restrict real-time evaluation.MethodsThis study ...

Distribution of xylem hydraulic resistance in fruiting truss of tomato influenced by water stress

open access: yes, 2003
In this study xylem hydraulic resistances of peduncles (truss stalk), pedicels (fruit stalk) and the future abscission zone (AZ) halfway along the pedicel of tomato (Lycopersicon esculentum L.) plants were directly measured at different stages of fruit ...

Investigating the mechanisms of desiccation tolerance in the resurrection plant, myrothamnus flabellifolius (WELW)

open access: yes, 1999
Biliography : leaves 162-184.Resurrection plants, including Myrothamnus flabellifolius, grow in shallow soil upon rocky outcrops where they experience regular periods of water stress. Associated with this is light stress.

The Water Status Measurements Associated with Plant Growth

open access: yesEnvironment Control in Biology, 2007
The process of cell elongation from the viewpoint of plant-water relations and the effect of excision in the zone of elongation on changes in the water status are discussed. The excision effect on changes in water potential was evaluated after measuring turgor before excision and after excision in growing tulip tepals, and it was found that the size of

Planning the integration of ex situ plant conservation in Tasmania

open access: yes, 2013
Tasmania has a strong record of successful in situ plant conservation but there will always be a role for the integration of various ex situ measures into a plant conservation program due to pressure by threatening processes on wild populations.

Hydraulic conductivity of whole root system is better than hydraulic conductivity of single root in correlation with the leaf water status of maize

open access: yes, 2006
Under hydroponic culture conditions, we studied the relationship between two different types of root hydraulic conductivity of maize (Zea mays L.) and its leaf water status. The results have proved the inaccuracy of the single root hydraulic conductivity

A study of the root surface phosphatase activities of three species of higher plants: Juncus effusus, Phragnutes australis, and Typha latifolia [PDF]

open access: yes, 1993
The aim of this project was to investigate a possible link between environmental phosphorus status and the root surface phosphatase activities of three species of emergent macrophytes, with a view to assessing their potential for use as "biondicators ...
