Management Strategies For Pitch Canker Infected Año Nuevo Stands Of Monterey Pine, Valerie A. Loe Jun 2010

Management Strategies For Pitch Canker Infected Año Nuevo Stands Of Monterey Pine, Valerie A. Loe

Master's Theses and Project Reports

The future resilience of Pinus radiata D. Don (Monterey pine) is dependent upon the development of a silviculture program inclusive of either preventative or management techniques for the potentially fatal pitch canker disease (Fusarium circinatum Nirenberg and O’Donnell [=F.subglutinans (Wollenw. & Reinking) Nelson et al. f. sp. Pini). As an ecologically and commercially valued species, a myriad of factors threaten the genetic resources of the geographically limited natural range. This study evaluated the effectiveness of uneven-aged forest management for regeneration success in the native, pitch canker infected Año Nuevo stand at Swanton Pacific Ranch in Davenport, California. Seedling survival ...


Analysis Of A Pinus Radiata Seed Stock Field In The Native Año Nuevo Stand In California, Christina Brassey Dec 2009

Analysis Of A Pinus Radiata Seed Stock Field In The Native Año Nuevo Stand In California, Christina Brassey

Master's Theses and Project Reports

This study was a part of the international collaborative IMPACT project, which aims to address the potential threat that the pitch canker disease poses to the use of Pinus radiata D. Don in plantations in New Zealand, Australia, and Chile. A field trial of 264 seedstocks was planted adjacent to a native stand of pitch canker infected P. radiata on the central coast of California, and disease symptom development was recorded over a period of 3 years. The results did not correlate with a greenhouse study of the same seedstocks inoculated with Fusarium circinatum Nirenberg & O'Donnell, the causal agent ...


Development Of A Laboratory Protocol For The Micropropagation Of Monterey Pines (Pinus Radiata), Año Nuevo Stand, Karen E. Wells May 2009

Development Of A Laboratory Protocol For The Micropropagation Of Monterey Pines (Pinus Radiata), Año Nuevo Stand, Karen E. Wells

Master's Theses and Project Reports

Monterey pine (Pinus radiata), a native tree to California and two Mexican islands, is important both ecologically and economically. Outside native stands, Monterey pines are grown for landscaping in California and on plantations around the world. Pitch canker, a disease caused by the fungus Gibberella circinata Nirenberg & O’Donnell (Fusarium circinatum Nirenberg and O'Donnell) is threatening the survival of Monterey pines. The disease currently affects Monterey pines in many parts of the world including the native stands. No effective chemical or biological control is available but some Monterey pines show resistance to the disease. The purpose of this project ...
