The influence of acid rain and drought on early growth and development of jack pine and balsam poplar
(1994)
The influence of "acid rain" (watering with tap water acidified to
pH 3.0 ) and drought on jack pine seedlings and balsam poplar cuttings
growing in two different soil types was studied in a short-term greenhouse
experiment. ...
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 ...
Ground speed : its influence on the direct seeding of jack pine (Pinus banksiana Lamb.) with the Bracke scarifier
(1993)
The effects that ground speed and obstacle height have
upon microsite creation by the Bracke scarifier and upon the
seeding characteristics of the integral seeder were studied.
The study was conducted in a former gravel ...
Pollen pool heterogeneity in jack pine (Pinus banksiana Lamb.) : a problem for estimating population outcrossing rate?
(1990)
Pollen pool heterogeneity, which violates an assumption
of the mixed-mating model, is one of the major problems
facing population geneticists concerned with measuring
plant mating systems. In the present study, isozyme ...
