Frost hardiness of balsam poplar (Populus balsamifera L.) during the spring dehardening period
(1990)Changes in the frost hardiness of balsam poplar (Populus balsamifera L.) cuttings from four populations along a latitudinal transect from N. Wisconsin to Bearskin L, Ontario, were examined during the spring of 1987. ... -
Genecology of jack pine in north central Ontario
(1995)To understand the pattern of adaptive variation of jack pine in north central Ontario better, short-term provenance tests were established. Seed was collected from 64 sites to the east and west of Lake Nipigon and grown ... -
Genetic variation in the frost hardiness of Pinus banksiana Lamb. (jack pine) in Northwestern Ontario
To estimate the level and pattern of variation in frost hardiness, artificial freezing tests of 64 provenances of jack pine were conducted. The provenances originated from northern Ontario. Seedlings of the provenances ... -
