Abstract:

Abstract The Theaceae tribe Gordonieae contains trees with desirable ornamental characteristics and adaptability to a broad range of environmental conditions. To develop an effective protocol for vegetative propagation of five taxa in the tribe, terminal softwood, semi-hardwood, and hardwood cuttings were collected from these trees and treated with either 0, 2500, 5000, 7500, or 10000 ppm of the potassium salt of indolebutyric acid (K-IBA). The concentration of K-IBA only affected rooting percentage of hardwood cuttings of Franklinia alatamaha, Gordonia lasianthus, and Schima remotiserrata and

Abstract:

The influence of some external factors important for the rooting of semi-hardwood and hardwood peach cuttings planted in a mist propagation unit with a bottom heat bench were investigated. Cuttings from 1-year-old trees had relatively higher rooting percentages after storage at 2–4�C for 2 and 3 months, while cuttings from 11-year-old trees had the highest rooting percentage at the first planting. Cold storage appeared to decrease rooting of the cuttings from 11-year-old trees significantly. The greatest length of semi-hardwood cuttings was 15–20 cm long.

Abstract:

`Guardian' peach rootstock has shown improved survivability in areas where root-knot nematode and peach tree short life are a problem. Many peach rootstocks are typically propagated from seed. Availability of seed may vary and the long-term genetic uniformity of rootstock material may be difficult to maintain due to out-crossing during seed production. A reliable, successful vegetative propagation method would potentially increase the rate at which material could be made available and more closely ensure genetic uniformity.

We examined the effects of single-tree selection cutting on cavity trees and snags in a northern hardwood stand immediately prior to the second cutting. Marking followed guidelines proposed by Arbogast, C., Jr. (1957. Marking guides for northern hardwoods under selection system. US For. Serv. Res.

Abstract:

The effect of iron deficiency on adventitious rooting of peach hardwood cuttings (cv. Early Crest) was investigated. The results showed significant differences between rooting, root numbers and dry weights of roots per cutting. Significant differences were also shown between cuttings from healthy trees (control) and cuttings from iron-deficient trees. Leaf samples taken from iron-deficient trees (before the application of an iron compound) exhibited higher levels of K, Ca and Mn than healthy trees, although the iron content was higher in the healthy tree samples. The bark of healthy trees show

This study aimed at determining the effects of propagation medium and cutting types on the early growth performance of fig (Ficus carica L.) root and shoot. The experiment was conducted at the Glasshouse and Nursery Complex (GNC), International Islamic University Malaysia (IIUM). The split-plot design was employed with the main plot (propagation medium) and sub-plot (types of cutting). The propagation medium were sand and topsoil (1:3) (M1), topsoil, peat and sawdust (1:1:1) (M2) and peat and perlite (1:1) (M3). Two types of cutting were semi-hardwood (C1) and hardwood (C2).

Abstract:

Abstract The 1987 Forest Survey of Mississippi shows a slight increase in forest area and a substantial gain in hardwood inventory. Hardwood gains, appearing in all diameter classes, suggest an increase in quality, but hardwood users generally believe quality is declining. By our analysis, volume of top quality hardwood declined while volume in other grades increased. When compared on individual trees, Forest Survey grades agreed only about one-half the time with grades assigned by a hardwood specialist.

Abstract The volume of healthy trees of commercial size in the maple-birch forest type measured during the last two Forest Inventory Analysis surveys of Wisconsin grew at 2 to 3%/yr for sawtimber, and 3 to 4% for poletimber, with substantial differences among species. However, from 1967 to 1989, the real price of logs decreased or remained constant for most grades and species. The decrease was especially large for high grade logs. The only exceptions were red oak and elm, whose prices increased at 1 to 2%/yr, for all grades. As a result, the average value growth rate of the trees that did not

Alternatives to the traditional treatment of effluent, irrigation back onto pasture, may prove valuable for farmers. Here we present the results from the first two years of a trial set up to test the potential of cut-and-carry coppiced hardwoods (poplars and willows) in taking up nitrogen from fresh effluent and providing fodder on a dairy farm. Three blocks each of Argyle poplars and Tangoio willows were planted as 1.2 m stakes on a dairy farm in southern Wairarapa in September 2001. One block of each species was irrigated with fresh farm dairy effluent at a high rate, about 5 mm per week, th

Abstract:

The retention forestry approach is considered as one of the potentially effective tools for sustainable forest management for conservation of biodiversity in managed temperate and boreal forests. Retention of old-growth forest structures (e.g., very large old living trees) in forest stands during clear-cutting provides maintenance of key habitats for many old-growth forest interior-species. Most of ecological studies on green tree retention (GTR) consequences for biodiversity have been focused on birds. However, the long-term studies of GTR impacts on forest birds are very poor.

Abstract Using 5 yr remeasurement data from even-aged natural loblolly pine (Pinus taeda L.) stands in the Georgia Piedmont, a system of growth equations was developed to project pine yield over time that accounts for hardwood competition. In this system, the increase in the proportion of hardwood basal area over time is estimated, then the projected pine basal area and trees per acre are adjusted inversely to account for this increase. The parameter estimates for this system ensure compatibility between volume prediction and projection equations and the proportion of hardwood basal area, pine

Abstract:

Abstract Damage to residual trees after cable logging was observed in two northern hardwood stands in Pennsylvania. In the first stand, primarily red maple and black cherry, only 8% (by basal area) sustained major damage. Felling was the major source of damage, as the amount due to yarding was negligible. The second stand, a mix of red maple, red oak, and black birch, sustained 10% major damage. The results were similar to observations made in West Virginia, and support the effort to use cable yarding for partial cuts in hardwood stands. North J. Appl. For. 8(1):15-17

Abstract:

For satisfactory growth, most high-value hardwood species demand a deep, fertile, moist but well drained soil. Intensive competition control during the early years after planting is a necessity. Close spacing is recommended, with gradual release of crop trees to promote high-quality stem development. For good hardwood growth on soils of marginal fertility or poor drainage or on sites where intensive management cannot be guaranteed, it is recommended that a mixture of several hardwood species be planted.

At three previously thinned, even-aged northern hardwood stands affected by the 1998 ice storm, we evaluated the responses of trees in plots given a rehabilitation treatment, and compared findings to adjacent untreated areas. In both the rehabilitated and untreated areas mortality seemed consistent with regional norms for northern hardwood stands. Trees that died after the storm had essentially complete crown loss due to ice loading, and 12% of living trees lost at least half of their crown. In both sets of plots, epicormic branching within the crown led to crown rebuilding, resulting in high
