In a 40-year-old western white pine plantation developed as a seed production area, heavy thinning and application of fertilizer in the fall significantly increased strobilus production the following spring. Applying fertilizer increased seed weight and cone length significantly, but thinning did not. Insects severely damaged the cone crop in the thinned stand. This study indicates that abundant seed crops, relatively free from insect damage, may be produced without expensive thinning and area preparation operations.

Excerpt from Effects of Thinning and Fertilizing on Production of Western White Pine Seed Seed production areas and seed orchards have been established to fill this need. A seed production area is typically a stand of desirable trees set aside for seed production and usually given special cultural treatments to increase seed production. In contrast, a seed orchard is a plantation of trees (established by grafting or from cuttings or seedlings) that have been rigorously selected and have been or are being tested to determine their genetic worth. Typically, seed production areas provide a temporary source of seed until seed orchards come into production and provide markedly improved seed. The number of seed production areas is increasing rapidly-already acres are now devoted to this use in the United States (31) About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
