Photoperiod control of container seedlings


Research at the Pacific Forest Research Centre, Victoria. on the use of photoperiod lighting to grow seedlings of white spruce, Engelmann spruce, white x Engelmann hybrids, mountain hemlock, and amabilis fir in container nurseries is reviewed. Factors investigated were the critical minimum and maximum light intensities required by the above species when using photoperiod lighting; comparisons of natural daylength extension and cyclic lighting (interruption of the darkness); the effect of photoperiod lighting failure on tree seedling growth; and the influence that photoperiod lighting in the nursery has on tree seedling growth in the following year.
