Western Hemlock and western red cedar seedlings were grown in a container greenhouse system under four different nursery cultural treatments. A stock quality assessment procedure was developed to characterize a seedling's drought avoidance (i.e. needle and root surface area, needle resistance, root growth capacity), drought tolerance (i.e. osmotic potential) and cold tolerance (i.e. frost hardiness, low temperature root growth capacity) capabilities developed through the various nursery cultural treatments. Results showed western hemlock seedlings in the short-day treatments and western red cedar seedlings in the moisture stress treatments had the best stock performance potential characteristics.
