Internal fruit rot detection drives demand for precise plant measurement technologies

Algerian researchers have identified Alternaria alternata as the pathogen responsible for pomegranate heart rot in Algeria, according to a study published in the Journal of Fungi in 2026. The findings confirm the disease as an emerging quality risk for commercial orchards, particularly because infections develop inside the fruit and may remain undetected during harvesting and packing.

Quality risk

Field surveys conducted between 2022 and 2025 in major production areas showed that the fungus causes browning and dry rot of arils while the outer peel often appears normal. This internal development increases the risk of hidden defects entering supply chains, affecting market quality and postharvest performance.

Scientific proof

Controlled inoculation trials reproduced the same symptoms under laboratory conditions, confirming the pathogen’s direct role in the disorder. The study also documented variation in disease severity among cultivars, indicating that varietal response could influence orchard risk levels and future management decisions.

Measuring impact

Beyond laboratory diagnosis, the research highlights the importance of accurate plant monitoring in evaluating crop condition and disease impact. In plant physiology and orchard assessment work, instruments such as the CI-202 Portable Laser Leaf Area Meter developed by CID Bio-Science are designed to measure leaf area and canopy characteristics quickly without damaging plant tissue. These tools help researchers quantify plant growth, detect stress signals and assess how disease pressure influences productivity in commercial orchards.

Operational response

Combining laboratory diagnostics with field-based plant measurement technologies strengthens early detection and monitoring systems in commercial orchards. Such integrated approaches support more targeted disease management and help growers protect fruit quality throughout the supply chain.
