Height Data

The tenth-year survival and height data for an experiment which compared five depths of planting (−2, −1, 0, +1 and +2 inches), and two methods of planting, slit (with spade) and wedge (side-hole, with spade), of red pine, Pinus resinosa Ait., are given.Survival was found to increase with depth of planting whereas height growth was best with shallow planting in the 0 to +1 range. As the effect on height growth was minor in comparison with the effect on survival it was concluded that planting slightly below nursery level was best.The poorer survival (about 10%) and height growth (about 13%) of the trees planted by the slit method was not significant, although the experimental design permitted only a coarse comparison.

Early Fall

Young red pine (Pinus resinosa Ait.) trees were grown under three watering treatments from late summer until early fall and under two watering treatments again the next spring. Size of apical buds, date of bud swell and bud burst in the spring, number of needle fascicles on the new shoots, shoot length, and needle-fascicle spacing were related to the first treatments. Most of these plant responses were correlated with bud size, and the correlations were unaffected by the spring watering treatments. The effect of treatments was on magnitude only, i.e. on mean sizes or mean numbers of the plant organs.In all cases in this experiment watering treatments during elongation had no effect on the results. Therefore in a species such as red pine, with determinate height growth, environment during bud formation played an important role in determining later shoot responses by acting on the bud size.Possibly the relationships reported here are genetically characteristic, unalterable by environment or at least by water alone. In this case the effect of environment on the trees was a proportionate increase or decrease in the size or number of plant organs.

Growth Data

Growth data are presented for a 72-year-old plantation of red pine (Pinus resinosa Ait.) at Rockland, Ontario, part of which was thinned four times between 1938 and 1972 and part of which was left unthinned. Height growth in both parts ceased between stand ages 67 and 72 years. During the same 5-year period, gross periodic increment was 551 ft3/ac (38.6 m3/ha) in the thinned stand while in the unthinned stand mortality exceeded gross periodic increment by 187 ft3/ac (13.1 m3/ha).

AbstractHeight growth and number of side branches developing the first growth season after chemical suppression of the European pine shoot moth, Rhyacionia buoliana (Schiff.), were measured on 40 treated and nontreated plots of red pine, Pinus resinosa Ait., in Michigan. Some plots had been treated during the summer-treatment period and some during the spring-treatment period. Summer treatment increased the height growth and number of side branches over no treatment; the degree of chemical suppression was useful in estimating tree growth during the following growing season. In contrast, spring suppression had no effect on height growth and number of side branches.

The survival and growth of ectomycorrhizal and ectendomycorrhizal red pine (Pinus resinosa Ait.) seedlings transplanted from a nursery onto iron tailings were examined. Seedlings were inoculated with the E-strain fungus BDG-58 (Complexipes sp. Walker emend. Yang & Korf), Phialophora finlandia Wang & Wilcox, Pisolithus tinctorius (Pers.) Coker & Couch, or Suillus subluteus (Peck) Snell ex Slipp & Snell. The first two isolates are ectendomycorrhizal fungi and the last two ectomycorrhizal fungi. Two-year field data on the tailings indicated a mycorrhizal treatment effect only in root-collar diameter at the end of the first growing season. The mycorrhizal treatments had a higher survival rate than the controls, with BDG-58 and Ph. finlandia seedlings having the greatest percent survival. Results from freehand root sections indicated that ectendomycorrhizae persisted in young roots of 4-year-old red pine seedlings that had been transplanted 2 years previously.

Four experiments were established at Orono nursery to study the effects of root dipping (Kaolin clay slurry) on survival and growth after outplanting of white spruce (Picea glauca (Moench) Voss), red pine (Pinus resinosa Ait.) and white pine (P. strobus L.). There were early- and late-season spring plantings carried out after holding the trees in unrefrigerated storage in kraft-polyethylene bags for periods up to 3 weeks. Results of the outplantings were examined in terms of 5-year survival and growth data.The results show that the clay dipping was usually of no benefit and sometimes damaging. Late planting generally resulted in decreased survival and poorer growth. Storage of trees from the early lifting showed no significant decreases in survival and growth, but storage of spruce in the late lifting showed reduced survival and growth in proportion to duration of holding.

Provenance Test

Survival, total height and diameter at breast height (DBH) were measured in the fall of 2005 in a 48-year-old red pine (Pinus resinosa Ait.) provenance trial growing in northwestern Ontario. There was significant variation in both height and diameter among the 23 provenances. Generally, westerly provenances performed well while those from the Maritime Provinces exhibited relatively poor growth. Considering that the plantation is at the northern biological range of red pine, survival was high, averaging 96% after 48 years. Provenances with the best growth rates exceeded a volume of 420 m3 ha-1. Some provenances from Minnesota and Wisconsin as well as Fort Frances, Ontario exhibited superior growth and should be considered as seed sources for future planting programs in northwestern Ontario.

Pine Cones

The seed capacity of red pine cones varies from about 30 to over 110, depending on the size of the cone and its position in the tree crown, and is determined by the number of ovules that are structurally complete at the time of pollination. These ovules occur in a central "productive" region and constitute less than one-half of the total. The remaining ovules, most: of which are in the proximal part of the cone, never become structurally perfect, and do not contribute to seed production. Abortion of ovules in the productive region usually reduces seed production efficiency to 50–60%, and is accompanied mainly by withering of the nucellus in the first year and failure to produce archegonia early in the second year. The extent of ovule abortion during the first year varies indirectly with cone size, seed capacity, and height in tree.

Fifteen-year results are presented for a thinning experiment made in 13-year-old red pine (Pinus resinosa Ait.), designed to compare growth of trees in 4-tree clumps with that of uniformly spaced trees, in both cases growing at 890 stems/ha. By the end of the period, average crown size, form class and height were about the same for both stands, but growth by trees in clumps had been less for dbh and for basal area and total volume per hectare. Clumped trees had a significant tendency to lean away from each other. It was concluded that control of inter-tree spacing at planting or thinning is justified to the extent that clumps of more than three adjacent trees be avoided.

Survival And Growth

In 1997, a restoration of Pinus culminicola was established under three exclusion areas: E1 = cattle plus small mammal exclusion, E2 = cattle exclusion and E3 = no exclusion (free range), in the Cerro El Potosi Protected Natural Area, located in Nuevo León, Mexico. The objective of this study was to determine the survival rate and the increase in diameter and height of Pinus culminicola individuals at three and 17 years after planting. The results show differences between 2000 and 2014 in survival rate and diameter and height growth in the three exclusion areas; E1 and E2 recorded higher averages. The main causes of mortality in this species are attributed to extreme weather conditions and the damage caused by cattle and small mammals.
