Crown dynamics in Pinus resinosa Ait. : analysis and stochastic description of branch production, branch extension growth and foliage dry weight---branch length relationships
The development of the crown structure of Pinus resinosa Ait. was analysed in terms of three component processes of tree growth: the number of first order branches per whorl within the crown, the annual extension increments ...
Ten-year growth response of 45-year old Pinus banksiana Lamb. to urea fertilization and low thinning
The objectives of this investigation were 1) to examine the duration and pattern of jack pine growth response to urea fertilization and low thinning, and 2) to examine methods commonly used in the measurement of ...
Effects of wind induced soil moisture stress on the germination and early growth of Pinus banksiana Lamb. on three soil texture types
A controlled environment wind tunnel was used to produce three wind speeds and hence three soil drying rates in order to study the effects of soil moisture stress on seeds and germinants of Pinus banksiana Lamb, planted ...
