MULTI-PURPOSE CHESTNUT CLUSTERS DETECTION USING DEEP LEARNING: A PRELIMINARY APPROACH [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
In the early 1980′s, the European chestnut tree (Castanea sativa, Mill.) assumed an important role in the Portuguese economy. Currently, the Trás-os-Montes region (Northeast of Portugal) concentrates the highest chestnuts production in Portugal ...

Demographic and genetic factors affect the use of translocation for evolutionary rescue: A case study of American chestnut using simulation

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
These findings underscore the importance, complexity and flexibility of strategic translocations for ensuring the recovery of plant species limited by adaptive genetic diversity. Abstract For many plant species at risk, recovery depends on supplementing populations with adaptive genetic diversity through translocations but specific introduction ...

Distribution and population structure of the chestnut blight fungus in Romania

Plant Protection Science, 2015
The occurrence of chestnut blight (Cryphonectria parasitica) was studied in 2011-2012 at 13 locations in the main chestnut growing areas of Romania. Infections were detected at four localities.

Optimal strategies for utilizing host plant distributions to slow the spread of plant pests

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Containment of invasive species can be made markedly more cost‐effective by prioritizing landscape features that naturally impede spread. Targeting treatments around host‐plant gaps supports a clear operational rule: use mating disruption where densities are low to prevent establishment and concentrate pesticides where densities are high to suppress ...

Virulence, ligninolytic enzymes and metabolic profile of Cryphonectria parasitica virulent and hypovirulent strains Converted by CHV1 hypovirus

Millenium, 2020
Introduction: Cryphonectria parasitica, the causal agent of chestnut blight, causes necrotic lesions (so-called cankers) on the bark of stems and branches of susceptible host trees. Cryphonectria hypovirus 1 (CHV1) infects C.

Biological control of chestnut blight with hypovirulence : a critical analysis

, 2004
Most hypovirulence in the chestnut blight fungus, Cryphonectria parasitica, is associated with infection by fungal viruses in the family Hypoviridae. Hypovirulence has controlled chestnut blight well in some locations in Europe and in Michigan in the ...

Cyto-molecular characterization of rDNA and chromatin composition in the NOR-associated satellite in Chestnut (Castanea spp.)

Scientific Reports
The American chestnut (Castanea dentata, 2n = 2x = 24), once known as the “King of the Appalachian Forest”, was decimated by chestnut blight during the first half of the twentieth century by an invasive fungus (Cryphonectria parasitica).

An Artificial Inoculation Protocol for Greenhouse Resistance Screening of Loblolly Pine Seedlings Against Brown Spot Needle Blight

Forest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Brown spot needle blight (BSNB), caused by the fungal pathogen Lecanosticta acicola, has been rapidly increasing in incidence and severity on loblolly pine (Pinus taeda), the most dominant and commercially important pine species in the southeastern United States.
