Exploratory work was performed over a 2-year period to determine if needle fascicles of lodgepole pine could be easily rooted. Seedlings of 2, 4, and 6 years of age were used as stock plants. Rootability was inversely related to age of stock plant. A medium aggregate perlite proved superior to other rooting media. More cuttings rooted from December and January collections than when taken in October or March. Treatment of cuttings with Rootone, or IBA, or IBA plus kinetin or adenine seemed most beneficial. Results with IPA were erratic and of less value. The use of adenine or kinetin alone was of no value. Application of a 23-19-17 fertilizer (ΒΌ lb/100 gal water) through the mist system was detrimental. Maximum rooting with any combination of treatments was 7.5 percent (control 0.2 percent) during the first year and 20 percent (control 6.7 percent) the second year. These conclusions were based on very small numbers of rooted cuttings and should be considered tentative.
