Automatic detection of regions in spinach canopies responding to soil moisture deficit using combined visible and thermal imagery [PDF]

, 2014
Thermal imaging has been used in the past for remote detection of regions of canopy showing symptoms of stress, including water deficit stress. Stress indices derived from thermal images have been used as an indicator of canopy water status, but these ...

Pre-Harvest Salicylic Acid Application Affects Fruit Quality and Yield under Deficit Irrigation in Aristotelia chilensis (Mol.) Plants

Plants, 2023
Salicylic acid (SA) application is a promising agronomic tool. However, studies under field conditions are required, to confirm the potential benefits of SA. Thus, SA application was evaluated under field conditions for its effect on abscisic acid levels,

How Does Silicon Mediate Plant Water Uptake and Loss Under Water Deficiency?

, 2018
In plants, water deficiency can result from a deficit of water from the soil, an obstacle to the uptake of water or the excess water loss; in these cases, the similar consequence is the limitation of plant growth and crop yield.

Retrieval of Leaf Area Index (LAI) and Soil Water Content (WC) Using Hyperspectral Remote Sensing under Controlled Glass House Conditions for Spring Barley and Sugar Beet [PDF]

, 2010
Leaf area index (LAI) and water content (WC) in the root zone are two major hydro-meteorological parameters that exhibit a dominant control on water, energy and carbon fluxes, and are therefore important for any regional eco-hydrological or ...

Review of Plant Water Status Measurement Techniques

, 2022
The growth of the plant largely depends on the available water and soil. Soil supports the plant in mechanical ways and acts as a nutrient reservoir for its growth. Not only for plants but also for all living things, water plays a significant role in the

Arbuscular Mycorrhiza Symbiosis Enhances Water Status and Soil-Plant Hydraulic Conductance Under Drought

Frontiers in Plant Science, 2021
Recent studies have identified soil drying as a dominant driver of transpiration reduction at the global scale. Although Arbuscular Mycorrhiza Fungi (AMF) are assumed to play a pivotal role in plant response to soil drying, studies investigating the ...

A novel, non-invasive, online-monitoring, versatile and easy plant-based probe for measuring leaf water status

, 2008
A high-precision pressure probe is described which allows non-invasive online-monitoring of the water relations of intact leaves. Real-time recording of the leaf water status occurred by data transfer to an Internet server.

High Levels of Shading as A Sustainable Application for Mitigating Drought, in Modern Apple Production

Agronomy, 2021
The sustainability of reducing light in apple orchards under well-watered (ww) and water stress (ws) conditions was evaluated for water relations, plant gas exchanges, fruit growth, yield determinants, and fruit quality over three years.
