Book excerpt: This book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.

Available in PDF, EPUB and Kindle. Book excerpt: Foresters often need information on the cost effectiveness of manual and chemical release treatments for individual and combined species in young mixed-shrub communities. A study in northern Califomia evaluated five manual and chemical treatments and their effect on several shrubs and grasses. Treatments were grubbing at age 1 to 2- and 4 ft (0.6- and 1.2-m) radii, regrubbing and expanding the 2-ft radii to 4 ft, regrubbing and expanding the 4-ft radii to 6 A (1.8 m) at age 4, and applying Velpar herbicide to the entire plot at age 2. Five years after initial manual release and 4 years after chemical release, ponderosa pine (Pinus ponderosa Dougl. ex Laws. var. ponderosa) stem caliper at 12 in. (30 cm) above mean ground line differed significantly between Velpar and the untreated control, 2-ft radius, 4-ft radius, and 2-ft radius expanded to 4 ft. Expanding the radius from 4 to 6 feet provided a pine stem caliper that differed significantly from that in the control, and the 2-ft and 4-ft radii treatments. Additional analyses with ponderosa pine seedling height also indicated significant differences among treatmenu that were generally similar to those above. Differences among the six treatments, which are presented in 15 comparisons of stem caliper and treatment production rates, provide forest managers with growth and cost comparisons, and should aid them in selecting the release treatment best suited to their particular situation.

This book was released on 1975 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind-pollinated families from four geographic areas in the northern Sierra Nevada were tested in the nursery. For every area, the native families differed significantly from each other in 1-year seedling height, and in 2-year height, diameter, and stem volume. Family growth was poorly correlated with family seed weight; it was independent of germination speed and seed parent stem volume. The size of planting stock can be improved and small-grade seedling production decreased by eliminating from future collections seed trees whose families show poor growth in the nursery.
