Chlorophyll fluorescence data collected on Mount Etna, Sicily, 2017

, 2022
The dataset contains chlorophyll fluorescence data from different genotypes of two Senecio species on Mount Etna, Sicily. In 2017, multiple clones of c.40 genotypes for each of two Senecio species were transplanted at four elevations (500m, 1000m, 1500m,

Predicting grapevine stem water potential (Ψstem) using UV‐visible‐NIR spectroscopy across contrasting vineyard environments

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change is intensifying water scarcity in viticulture, increasing the need for rapid and reliable tools to monitor vine water status. Spectroscopic techniques have emerged as promising approaches for rapid assessment of plant water status, although their robustness across different environments remains a key challenge.

Development of an Automated Low-Cost Multispectral Imaging System to Quantify Canopy Size and Pigmentation

Sensors
Canopy imaging offers a non-destructive, efficient way to objectively measure canopy size, detect stress symptoms, and assess pigment concentrations. While it is faster and easier than traditional destructive methods, manual image analysis, including ...

Application of Organic Superabsorbent Cellulosic Polymers (OSCPs) and Cyanobacteria on Reduction of Aeolian Losses

Land Degradation &Development, EarlyView.
ABSTRACT Establishing biocrusts on sandy surfaces in harsh desert environments presents significant challenges due to extreme ecological conditions. To address these challenges, this study examined the effects of two organic superabsorbent cellulosic polymers (OSCPs)—carboxymethyl cellulose (CMC) and guar gum (GUA)—on the establishment of ...

Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

PLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

Precision agriculture for water saving: The case of processing tomato and table grape

PLANTS, PEOPLE, PLANET, EarlyView.
Agriculture faces increasing pressure to produce high‐quality food while reducing water use under intensifying climate change and water scarcity. This study compared sensor‐based precision irrigation, drone monitoring, and near‐infrared spectroscopy with conventional farmer management in table grape and processing tomato production systems.
