Mycoflore des aiguilles de Pinus banksiana et Pinus resinosa. I. Champignons endophytes

Canadian Journal of Botany, 1989
The nature and distribution of the endophytic mycoflora isolated from healthy needles of Pinus banksiana and Pinus resinosa growing in plantations or natural stands infected with Scleroderris canker were investigated. Overall colonization rates of the needles were 68 and 89% for P. banksiana and P.

The impact of Sirex noctilio in Pinus resinosa and Pinus sylvestris stands in New York and Ontario

Canadian Journal of Forest Research, 2010
Sirex noctilio Fabricius has a long history as an invasive insect species in pine plantations throughout the Southern Hemisphere and has been recently discovered in North America, where it is uncertain how this insect will behave in pine ecosystems. To assess the impact and attack behavior of S.

INTRASPECIFIC VARIATION OF NUCLEAR DNA CONTENT IN PINUS RESINOSA AIT.

Canadian Journal of Genetics and Cytology, 1974
Pinus resinosa displays a rather uniform phenotype over a relatively small geographic distribution with a 9-degree latitudinal spread. DNA quantity per cell from 20 seed sources collected throughout the growing range varied significantly by a factor of 2.2 from the lowest to the highest amount. A south-to-north increasing DNA gradient was not observed

Mycorrhizal fungus colonization of Pinus resinosa Ait. Transplanted on northern hardwood clearcuts

Soil Biology and Biochemistry, 1993
Abstract An ordered succession in mycorrhizal fungus colonization occurred on red pine ( Pinus resinosa Ait.) root systems transplanted on three recently-cleared northern hardwood sites in northern Michigan, U.S.A. Ordered changes were related to tree age from transplanting, and were demonstrated experimentally by quantification of mycorrhizal ...

Timing and rate of bud formation in Pinus resinosa

Canadian Journal of Botany, 1971
During the 1969 and 1970 growing season buds were collected almost weekly from matched trees in northeastern Minnesota. Cataphyll primordia for the year n + 1 shoot began forming at the time that internodes in the year n shoot started elongating (late April) and continued forming until early September. Primordia for axillary buds started forming about
