Excerpt from Ponderosa and Lodgepole Pine Seedling Bud Burst Varies With Lift Date and Cultural Practices in Idaho Nursery Springtime warming allows for trees to break dormancy and begin growth. Figure 4 also shows the cumulative high temperatures before the two spring lifts. This summary of temperatures does not tell us what the requirements are for bud burst. It does show us the temperatures that have made the lodgepole pine seedling tops ready to grow immediately upon exposure to favorable conditions, on March 18. By April 8 they were beginning to grow ih-the nursery bed. We did not lift any trees between November 26 and March 18 because of frozen soil. When the frost finally left the ground in mid-march, the lodgepole seedlings broke bud very quickly in the greenhouse. Within 15 days nearly 100 percent of the trees broke bud, while in late November it took 45 days to achieve the same amount of bud burst. Three weeks later the seedlings were so close to breaking bud in the nursery bed that 14 percent did break bud in the time period between lifting and when they were placed in the greenhouse. This indicates that the lodgepole seedlings were coming out of dormancy before the spring lifts. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

In 1988, three studies were established as part of Experimental Project 995 to study lodgepole pine (Pinus contorta var. latifolia) survival and growth responses to site preparation in the Sub-Boreal Spruce zone of north-central British Columbia. The project examines the effectiveness of several mechanical treatments and localized high-intensity burning, with a focus on disc trenching, which is the most commonly used mechanical site preparation technique in this region. The importance of disc trench orientation, planting aspect, and planting position were investigated, as well as potential interactions between broadcast burning and disc trenching. This report presents 25-year results for the Bednesti North and Bednesti South experiments, and 19-year results for the Tanli experiment. Treatment effects are discussed in relation to: lodgepole pine establishment (survival and early growth to age 5); performance at approximately free-growing age (9 years); and early mid-term growth, stand volume, and site index (as measured at age 25). Of the mechanical treatments tested, coarse mixing was the most effective, resulting in approximately 1-m gains in lodgepole pine height over the control at age 25. This treatment is not practical from an operational perspective, however, and the more common technique of disc trenching with trees planted at the hinge produced the second greatest gains. In contrast, pine planted in trench furrows showed a trend of reduced growth relative to the control. Trench orientation was relatively unimportant, but there was a slight advantage to avoiding north-aspect planting positions. Although broadcast burning alone did not have a significant effect on pine growth, it consistently interacted with disc trenching to produce a mild magnification of responses to that treatment. Pine planted in long, narrow, intensely burned windrow strips were consistently larger than control pine throughout the 25-year assessment period, but they had poor form due to being essentially open-grown.
