Current Growth

The fertilizers, Mg at a rate of 100 lbs/acre and K at 200 lbs/acre, were applied around each of 15 red pine (Pinus resinosa Ait.) to promote increased growth in a 20-year-old plantation which had failed to fulfil growth expectations. Successive measurements of diameter and height showed that the fertilizers stimulated diameter significantly after the second growing season, but height only after the third growing season. Beneficial effect of fertilizer applications on diameter and height persisted, and the differences in diameter and height between treated and untreated trees at the end of the seventh growing season was equivalent to two years' current growth.

Suppression Process

Initial stem and root growth of trees that became suppressed within 30 years in a red pine (Pinus resinosa Ait.) plantation were poorer than those that became codominants. Stem and horizontal root extension improved later but then declined. The likelihood of suppression may have been initiated at or before planting. Inadequate development, perhaps through chance, of vertical roots that could tap moisture-holding layers at the 2.8 m depth in the well-drained loamy sand soil contributed to the suppression process.

Terrestrial Snails

A Red Pine (Pinus resinosa Aiton) plantation and adjacent Northern Red Oak (Quercus rubra L.) – Large-toothed Aspen (Populus grandidentata Michx.) woods, both of which developed from a savannah scrub beginning approximately 60 years ago, were compared with regard to terrestrial snail diversity and abundance. The comparison involved a 30-minute search of ten 1-m2 quadrats at ten sites in each habitat. In the Northern Red Oak – Large-toothed Aspen woodland, 13 species and 661 individuals were recorded, whereas, in the Red Pine plantation, six species and 24 individuals were recorded. In the Northern Red Oak – Large-toothed Aspen woodland, the most characteristic and abundant species was Novisuccinea ovalis (Say, 1817), which was present in 74 of the 100 quadrats and was represented by 460 individuals. In the pine plantation, the most common species was Zonitoides arboreus (Say, 1816), which was present in 16 quadrats and was represented by 17 individuals. This species was the second most common in the Northern Red Oak – Large-toothed Aspen woodland where 70 individuals were found in 34 quadrats. In both habitats, Z. arboreus was associated with downed wood. Other species occurring in more than 15% of quadrats in the Northern Red Oak –Large-toothed Aspen woodland were Strobilops labyrinthicus (Say, 1817), Glyphyalinia indentata (Say, 1823), and Euche motrema fraternum (Say, 1824). Although a lower number and diversity of terrestrial snails in the conifer plantation was expected, the contrast was greater than anticipated. The estimated abundance of 46 000 N. ovalis per hectare suggests the potential importance of these medium-sized snails in the relatively dry Northern Red Oak – Large-toothed Aspen ecosystem.

AbstractThe pine gall weevil has a 3-year life cycle on red pine (Pinus resinosa Ait.) in Michigan. Adults oviposit from June to August, depositing 1 to 10 eggs in a niche chewed in the bark of a branch internode. Larvae first emerge in August, feed as a group toward the cambium, and then radiate out along the xylem. Head capsule measurements from 1585 larvae indicate that there are three larval instars. Gall development begins in June of the second year, shortly after the larvae begin the second instar. The third instar commences in June of the third year. Pupation occurs in May of the fourth season; adult emergence follows in June. Overwintering occurs in the egg stage or in the three larval instars. Adults do not overwinter, and apparently three distinct broods occur in Michigan.

Growth data for a 62-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, are presented for the two stand conditions, together with associated product yields and economic implications of alternative treatments. The investment in thinning, when based on historical costs and revenues, was attractive: the thinning program increased net present worth at each stage. When based on current costs and revenues, with no increase at an assumed inflation rate, the investment in thinning was less attractive, and it was not proved conclusively that the thinning program would be profitable. Financial growth peaked at a rotation age of approximately 50 years.

AbstractChrysobothris orono Frost, a buprestid which attacks living red pine (Pinus resinosa Ait.) and jack pine (P. banksiana Lamb.), has a 2-year life cycle and two separate broods in Michigan. Adults emerge from May to July. The eggs are laid singly, usually on the southwest side of a tree; the fifth and sixth whorls from the top are the preferred oviposition sites. Larval eclosion usually occurs in early June. Each larva excavates a cell in the bark and causes the flowing pitch to coagulate into a large pitch mass. The first three instars feed in the bark and the last two instars feed in the xylem. Advanced larvae may reach the fourth instar by fall of the first year; overwintering occurs in the third and fourth instars. The fifth instar, which appears in the spring of the second year, bores a short L-shaped gallery in the xylem and plugs it with frass and wood chips to form a pupal cell. It pupates in the spring of the third year. Adults emerge by chewing through the plug and pitch mass. The bark cell and xylem gallery seldom injure the tree directly, but they remain as defects in the bole after the wounds have healed. Because damage is slight and the insect population low, C. orono is not likely to become an important forest pest.

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.
