Title: Genotype x shade effects for western hemlock.

Author: Johnson, G.R.; Cartwright, C.;

Date: 2005

Source: Canadian Journal of Forest Research. 35: 1496-1501

Publication Series: Scientific Journal (JRNL)

Description: Western hemlock (Tsuga heterophylla (Raf.) Sarg.) families were grown under different levels of shade for 2 or 3 years at two nursery sites to determine whether families performed differently relative to one another in the different shade environments. Differences were found both for levels of shade and families, but no family x shade interaction was found. Results suggest that families selected in full-sun environments (clearcuts or farm fields) may be well suited for use in silvicultural systems where seedlings are planted in understory conditions.
