Marie : Ontario Ministry of Natural Resources. This book was released on 1996 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the periodicity, fecundity, and asynchronsation in white pine pollen- and seed-cone production, methods need to be developed to produce both pollen and seed cones, thereby shortening the breeding cycle in advanced generation breeding. This paper presents a study designed to examine previous research on gibberellin treatments for pollen-cone production. Experiments were conducted on a breeding orchard of eastern white pine in Ontario, using clones of 6- or 11-year-old grafts in each of three treatment periods (May-June, June-August, and August-September 1994). Data were collected the following year when pollen and seed cones had emerged from the bud scales. Results presented include comparison of pollen cone and seed cone production between treated and untreated control grafts, and the differences in production among the three treatment periods.

This book was released on 2018-01-05 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Cone and Seed Yields in Young Western White Pines In the course of breeding western white pine (pinus monticola Dougl.) for resistance to blister rust (see Bingham, Olson, Becker, and others. 1969 and earlier), 18 years of data on cone and seed yields of individual trees from different geographic local ities have been accumulated. The protection of cones during development minimized losses due to insects and rodents; therefore, these data simulate the full reproductive potential of young trees in natural stands. Annual variation in cone production among geographic localities and individual trees thus is represented in these data. This information is indis pensable for practices of seed collection and seed orchard management which rely on knowledge relating to cone yields of individual trees and possibly on yields derived from controlled pollinations.

This book was released on 1969 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
