Download or read book Western Dwarf Mistletoe Infects Understory Jeffrey Pine Seedlings on Cleveland National Forest California written by Robert F. Scharpf and published by . This book was released on 1986 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many young, understory Jeffrey pines (Pinus jefreyi Grev. & Balf.) were found to be infected by western dwarf mistletoe (Arcerrthobium cantpylopodurn Engelm.) on Laguna Mountain, Cleveland National Forest, in southern California. Under heavily infected overstory, about three-fourths of the young pines (about 15 years old on the average) were infected by dwarf mistletoe. Infections per tree averaged about two and a half, two-thirds of these on the bole. Attempts to regenerate Jeffrey pine under an infected overstory in southern California will probably lead to a severely infected and damaged understory. Planting nonhost species or resistant selections of Jeffrey pine would be practical in managing dwarf mistletoe on these highly valuable forest recreational areas.

This book was released on 1982 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Young red firs (Abies magnifica A. Murr.) and white firs (A. concolor [Gord. & Glend.] Lindl. ex Hildebr.) on the Stanislaus National Forest, California, were inoculated with seeds of dwarf mistletoe (Arceuthobium abietinum) for 5 successive years. Only 3 to 4 percent of about 7000 seeds placed on branches resulted in infections. Second-generation infections developed and populations of the parasite built up on some trees but not on others after 17 years. Variables that appeared to regulate population increases included an 8- to 9-year average between inoculation and fruiting of plants, low rate of fruit production among female plants, low proportion of plants producing abundant fruit (100 or more/year), and irregular production of fruit on plants over the years, Death of infected branches also helped keep populations of the parasite in check. In vigorous, well-managed stands of young firs, dwarf mistletoe populations may not build up rapidly enough to result in serious losses.
