Download or read book Plant Breeding Reviews, Volume 27 written by Jules Janick and published by John Wiley & Sons. This book was released on 2010-04-07 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Breeding Reviews presents state-of-the-art reviews on plant genetics and the breeding of all types of crops by both traditional means and molecular methods. Many of the crops widely grown today stem from a very narrow genetic base; understanding and preserving crop genetic resources is vital to the security of food systems worldwide. The emphasis of the series is on methodology, a fundamental understanding of crop genetics, and applications to major crops. It is a serial title that appears in the form of one or two volumes per year.

Download or read book Seed Dissemination in Small Clearcuttings in North-central California written by Philip M. McDonald and published by . This book was released on 1980 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Download or read book Woody Plant Communities written by T.T. Kozlowski and published by Elsevier. This book was released on 2012-12-02 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Deficits and Plant Growth, Volume VI: Woody Plant Communities focuses on the water relations of woody plants in a community context. Organized into eight chapters, this book begins with a quantitative overview of sources of water available to woody plants. Separate chapters follow that discuss the water relations of coniferous, temperate hardwood, and tropical and subtropical forests and woodlands; apple and citrus orchards; closely related woody plants; and tea plantations. For each of these plant communities, emphasis is placed on hydrological cycles; water use and transpiration; absorption of water; and effects of environmental factors on soil and plant water balance. The effects of water deficits on physiological processes; vegetative and reproductive growth; yield of harvested products; drought resistance; and cultural practices affecting plant water balance and yield are also emphasized in this book. This volume will be useful to both researchers and those involved in the practice of growing woody plants for wood and fruit crops and for esthetic values.

Download or read book Conifer Seedling Mineral Nutrition written by R. van den Driessche and published by CRC Press. This book was released on 1990-12-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifer Seedling Mineral Nutrition provides a comprehensive review of conifer seedling mineral nutrition and its significance to forestry. The book covers relationships between mineral supply and uptake; the effects of nutrition on seedling growth; an integration of the ideas of T. Ingestad with classical growth analysis concepts; practical aspects of assessing nutrient status and details of fertilizing bare root and container nursery stock; and fertilizing vegetative propagules. The book also describes and illustrates Mycorrhizas, assessing their importance to plantation establishment in an analysis of recent papers reporting field trials. The effects of nutrients on stress resistance and establishment when applied in the nursery and while planting are discussed in the final chapter. It will prove useful to reforestation research workers, nurserymen, and silviculturalists and should be considered essential reading for forestry students.

Download or read book Improving Plantation Establishment by Optimizing Growth Capacity and Planting Time of Western Yellow Pines written by James L. Jenkinson and published by . This book was released on 1981 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seedlings of 27 sources of western yellow pines, selected in climates typical of the species, were raised in a nursery in the western Sierra Nevada. Seedling top and root growth capacities were periodically assessed during fall and winter, and field survivals of outplanted seedlings were evaluated in different climates with summer drought. In the nursery, four distinct, innate seasonal patterns of root growth capacity were defined in ponderosa pine from within and outside California, and two distinct patterns were defined in Jeffrey pine. Below snow line in the western Sierra Nevada, seedling survivals were higher in spring plantings than in a winter one, and for California sources than for others. In spring plantings above snow line, survivals for diverse local sources of ponderosa and Jeffrey pines were uniformly high, both on the western slope and east of the Sierra Nevada crest. The results demonstrate that seedlings of any source will have adequate growth capacity and will survive the first year on any well prepared site if they are lifted at the right time, stored properly, and planted in phase with warming soil trends.

Book excerpt: A trial of 36 species of Eucalyptus near Concord, California, found species of sufficiently rapid growth and good survival to merit further screening. Species from western Australia and of the subgenus Monocalyptus all failed on the site. E. camaldulensis, E. dalrympleana, E. glaucescens, E. grandis, E. nitens, E. ovata, and E. viminalis were the species with best survival and growth.
