  1. Some observations on the seedfall of sugar pine

    Increasing interest in the management of sugar pine (Pinus lambertiana Dougl.) in the mixed-conifer stands of the west slope of the Sierra Nevada has pointed out the need of certain silvical knowledge. One bit of required knowledge is the area that can be seeded effectively by a sugar pine tree. The forest manager must have this information in marking a stand to...

  2. Site preparation as an aid to sugar pine regeneration

    On many thousands of acres of cut-over timber lands in California, brush of various species has gained such control of the soil that the success of natural reproduction is problematical. This condition is particularly serious in the high site quality sugar pine-white fir and sugar pine-ponderosa pine types, where the maintenance of sugar pine in the stands is a...

  4. Population biology of sugar pine (Pinus lambertiana Dougl.) with reference to historical disturbances in the Lake Tahoe Basin: implications for restoration

    Historical logging, fire suppression, and an invasive pathogen, Cronartium ribicola, the cause of white pine blister rust (WPBR), are assumed to have dramatically affected sugar pine (Pinus lambertiana) populations in the Lake Tahoe Basin. We examined population- and genetic-level consequences of these disturbances within 10...

  5. Efficacy of early pruning to reduce the incidence of white pine blister rust on sugar pine (Pinus lambertiana)

    Sugar pine (Pinus lambertiana) is a five-needle pine native to the mixed-conifer forests of the Sierra Nevada and Cascade Ranges of western North America. Sugar pine has great aesthetic, ecological, and economic value and is among the largest of all pines. Like other five-needle pines, sugar pine is susceptible to white pine blister rust (WPBR), caused by the nonnative...

  6. Genetic variation in height and white pine blister rust resistance in sugar pine (Pinus lambertiana) - 15-year field trial results of three six-parent half dialers from three breeding zones

    Sugar pine (Pinus lambertiana) is a long-lived conifer species found in forest ecosystems from southern California to northern Oregon (USA). It is highly susceptible to white pine blister rust (WPBR), caused by the fungal pathogen Cronartium ribicola. Two long-term operational programs to develop populations of sugar pine with genetic resistance to WPBR, one in Oregon...

  7. Pinus lambertiana Dougl. Sugar Pine; Pinaceae Pine family

    Called "the most princely of the genus" by its discoverer, David Douglas, sugar pine (Pinus lambertiana) is the tallest and largest of all pines, commonly reaching heights of 53 to 61 m (175 to 200 ft) and d.b.h. of 91 to 152 cm (36 to 60 in). Old trees occasionally exceed 500 years and, among associated species, are second only to giant...

  8. Sugar pine and its hybrids

    Unlike most white pines, sugar pine (Pinus lambertiana) is severely restricted in its ability to hybridize with other species. It has not been successfully crossed with any other North American white pine, nor with those Eurasian white pines it most closely resembles. Crosses with the dissimilar P. koraiensis and P....

  9. Eliminating blister rust cankers from sugar pine by pruning.

    Well-stocked patches of vigorous advance reproduction are found in many deteriorating old-growth stands in southwestern Oregon. If carefully released from the over story, this reproduction can shorten the rotation length of the next crop by many years. Often sugar pine is the fastest-growing component of the reproduction, but it is frequently infected with blister rust...

  10. Release of sugar pine seedlings and saplings by harvest cutting.

    Sugar pine, the preferred species to grow on many forest areas in southwestern Oregon, is often seeded or planted on clearcuts there. Advance growth in the form of seedlings, saplings, and poles is common in the mixed- conifer type, and costly planting can be eliminated if this advance growth can be saved during logging and slash disposal. However, if the necessary...

  11. Grading sugar pine saw logs in trees.

    Small limbs and small overgrown limbs cause problems when grading saw logs in sugar pine trees. Surface characteristics and lumber recovery information for 426 logs from 64 sugar pine trees were examined. Resulting modifications in the grading specification that allow a grader to ignore small limbs and small limb indicators do not appear to decrease the performance of...

  12. An index of ripeness for sugar pine seed

    Immature or unripe seed may be one cause of the poor germination of sugar pine occasionally experienced in nursery practice or direct seeding projects. Ripeness of pine seed, or the time to harvest cones, is usually judged by a change from green to brown in the color of cones or by the development of a firm consistency in the endosperm. However accurately these...

    The majority of genomic research in conifers has been conducted in the Pinus subgenus Pinus mostly due to the high economic importance of the species within this taxon. Genetic maps have been constructed for several of these pines and comparative mapping analyses have consistently revealed notable synteny. In contrast,...

    Clark's nutcrackers (Nucifraga columbiana) are well known for using conifer seeds as their principal nutriment source. Seeds are primarily harvested from whitebark (Pinus albicaulis), piñon (P. edulis), limber (P. flexilis), southwestern white (P. strobiformis), Jeffrey (P. jeffreyi), and ponderosa (P. ponderosa) pine as well as Douglas-fir (Pseudotsuga menziesii...

  15. Distribution and frequency of a gene for resistance to white pine blister rust in natural populations of sugar pine

    The gametic frequency of a dominant allcle (R) for resistance to white pine blister rust, a disease caused by an introduced pathogen (Cronartium ribicola), in natural populations of sugar pine was estimated by the kind of leaf symptom expressed after artificial inoculation of wind-pollinated seedlings from susceptible seed-parent...

  16. Isolation of a full-length CC-NBS-LRR resistance gene analog candidate from sugar pine showing low nucleotide diversity.

    The nucleotide-binding-site and leucine-rich-repeat (NBS–LRR) class of R proteins is abundant and widely distributed in plants. By using degenerate primers designed on the NBS domain in lettuce, we amplified sequences in sugar pine that shared sequence identity with many of the NBS–LRR class resistance genes catalogued in GenBank. The polymerase chain reaction products...

    Sugar pine (Pinus lambertiana Douglas) is within the subgenus Strobus with an estimated genome size of 31 Gbp. Transcriptomic resources are of particular interest in conifers due to the challenges presented in their megagenomes for gene identification. In this study, we present the first comprehensive survey of the P. lambertiana...

    White pines exhibit both qualitative and quantitative resistance to white pine blister rust, which is caused by the fungal pathogen Cronartium ribicola (Sniezko et al. 2014). Species from several western U.S. States have a major gene at low frequencies that confers virtual immunity to the disease; and most also show heritable quantitative variation in infection...

    The health and regeneration of sugar pine (Pinus lambertiana), a major species in the mountain forests of California (USA), has been substantially affected by an exotic pathogen, Cronartium ribicola, which causes white pine blister rust. Seedlings from trees with major gene resistance (MGR) are being used to increase field survival in plantations. Partial resistance (...
