Effects of Thinning and Fertilizing on Production of Western White Pine Seed
Author: Burton Verne Barnes
Publisher:
ISBN:
Category : Forest regeneration
Languages : en
Pages : 22
Book Description
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.

Book Description
Excerpt from Seed Production of Western White Pine Since the aim is to determine the amount of seed produced per unit of area, the best method of studying seed production is by means of sample areas. These areas, may be from one - quarter of an acre to one-half of an acre in extent, in accordance with the density of the stand. Each sample area, however, should include at least 100 trees of the principal species composing the stand.
