This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Pest and disease pressures have traditionally driven the use of grapevine rootstocks in California. However, competing demands on the State’s water resources from an ever-increasing population and uncertainty of the supply under a changing climate mean that the water available for agriculture will continue to diminish. This inevitability has resulted in an increased interest in how rootstock characteristics influence scion growth and yield, and the impact rootstock parentage and genetics have on controlling these traits. This research consisted of three separate studies. The initial study examined 19 rootstocks on eight different field sites to determine rootstock impact on yields and pruning weights. The study spanned 11 years and general rootstock trends on yield and pruning weights were documented across the different soil types. Each field trial was positioned within a larger commercially operated winegrape vineyard of the same scion cultivar. Yield results were obtained by counting and weighing clusters at the time of harvest. Pruning weights were taken in winter after a professional crew pruned to normal standards for the given trellis and site characteristics. The results found that rootstocks group based on soil-based factors such as soil depth and water holding capacity, soil texture, soil chemistry and pathogen and pest pressure. This study laid the foundation for an examination of rootstock influence on scion phenological features examined in the second and third portion of this research. The objective of the second study was to determine the role that two grapevine rootstocks (110R and 101-14 MGT) have on scion phenology; specifically on leaf senescence and its influence on fruit ripening. To evaluate and classify rootstock influence on scion growth, development and senescence field trials were evaluated at three locations and measured: scion internode and stem diameter above the second cluster; cluster number; yield and pruning weight per vine; photon flux density (PFD) penetration into the cluster zone; abscisic acid accumulation in the leaves; and vine balance. The results suggest that 101-14 MGT shortens the length of the growing season compared to 110R based on the timing of senescence. 110R and 101-14 MGT also had a significant influence on scion growth characteristics. Vines grafted on 110R tended to have lower PFD in the cluster zone, more clusters, greater pruning and yield weights per vine in comparison to scions grafted on 101-14 MGT. Scions grated on 110R also had greater shoot internode lengths and stem diameters above the second cluster than those on 101-14 MGT. In the final study, a time efficient and cost effective container-based assay was developed to screen existing and newly bred rootstocks for their influence on the timing of leaf senescence timing and scion dormancy. A leaf senescence indexing guide was developed by evaluating rootstocks in two container-based shadehouse studies. The initial container assay was conducted over the course of two years and was established from dormant cuttings. It evaluated five commonly used rootstocks (101-14 MGT, 110R, 420A, Riparia Gloire, St. George), un-grafted and grafted with Cabernet Sauvignon under deficit and non-deficit irrigation regimes. A second container assay was established from herbaceous cuttings from a Ramsey (Vitis candicans x V. rupestris) x Riparia Gloire (V. riparia) population. These plants were un-grafted and exposed to deficit irrigation. In addition to scoring senescence, midday leaf water potential and stomatal conductance data were taken. Results from this study found that container assays can be successfully used to determine differences in senescence timing and are more easily observed under deficit irrigation. These results found that leaf senescence segregates in this population and identified selections with very early senescence, 33 and 105, and selections with late senescence, 56, 97 and 106.

Download or read book The Grape Genome written by Dario Cantu and published by Springer Nature. This book was released on 2019-11-13 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the current state of international grape genomics, with a focus on the latest findings, tools and strategies employed in genome sequencing and analysis, and genetic mapping of important agronomic traits. It also discusses how these are having a direct impact on outcomes for grape breeders and the international grape research community. While V. vinifera is a model species, it is not always appreciated that its cultivation usually requires the use of other Vitis species as rootstocks. The book discusses genetic diversity within the Vitis genus, the available genetic resources for breeding, and the available genomic resources for other Vitis species. Grapes (Vitis vinifera spp. vinifera) have been a source of food and wine since their domestication from their wild progenitor (Vitis vinifera ssp. sylvestris) around 8,000 years ago, and they are now the world’s most valuable horticultural crop. In addition to being economically important, V. vinifera is also a model organism for the study of perennial fruit crops for two reasons: Firstly, its ability to be transformed and micropropagated via somatic embryogenesis, and secondly its relatively small genome size of 500 Mb. The economic importance of grapes made V. vinifera an obvious early candidate for genomic sequencing, and accordingly, two draft genomes were reported in 2007. Remarkably, these were the first genomes of any fruiting crop to be sequenced and only the fourth for flowering plants. Although riddled with gaps and potentially omitting large regions of repetitive sequences, the two genomes have provided valuable insights into grape genomes. Cited in over 2,000 articles, the genome has served as a reference in more than 3,000 genome-wide transcriptional analyses. Further, recent advances in DNA sequencing and bioinformatics are enabling the assembly of reference-grade genome references for more grape genotypes revealing the exceptional extent of structural variation in the species.
Book Synopsis Grapevine in a Changing Environment by : Hernâni Gerós
Download or read book Grapevine in a Changing Environment written by Hernâni Gerós and published by John Wiley & Sons. This book was released on 2015-10-05 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grapes (Vitis spp.) are economically the most important fruit species in the world. Over the last decades many scientific advances have led to understand more deeply key physiological, biochemical, and molecular aspects of grape berry maturation. However, our knowledge on how grapevines respond to environmental stimuli and deal with biotic and abiotic stresses is still fragmented. Thus, this area of research is wide open for new scientific and technological advancements. Particularly, in the context of climate change, viticulture will have to adapt to higher temperatures, light intensity and atmospheric CO2 concentration, while water availability is expected to decrease in many viticultural regions, which poses new challenges to scientists and producers. With Grapevine in a Changing Environment, readers will benefit from a comprehensive and updated coverage on the intricate grapevine defense mechanisms against biotic and abiotic stress and on the new generation techniques that may be ultimately used to implement appropriate strategies aimed at the production and selection of more adapted genotypes. The book also provides valuable references in this research area and original data from several laboratories worldwide. Written by 63 international experts on grapevine ecophysiology, biochemistry and molecular biology, the book is a reference for a wide audience with different backgrounds, from plant physiologists, biochemists and graduate and post-graduate students, to viticulturists and enologists.
Download or read book Plant Aging written by Roberto Rodríguez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.

Book Synopsis Biology of the Grapevine by : Michael G. Mullins
Download or read book Biology of the Grapevine written by Michael G. Mullins and published by Cambridge University Press. This book was released on 1992-07-16 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information on the evolution, taxonomy, morphology, anatomy, physiology and genetics of grapevines has been scarce and thinly spread in the literature on horticulture and the plant sciences. This book aims to provide a concise but comprehensive overview of the biology and cultivation of the grapevine, accessible to all concerned with viticulture. After a description of the essential features of viticulture, including a concise history from antiquity to modern times, the taxonomy of the grapevine and the evolutionary processes which gave rise to the diversity within the Vitaceae is considered. Particular attention is paid to the genera Vitis and Muscadinia, which are considered a reserve of genetic variation for the improvement of grapevines. A description of the vegetative and reproductive anatomy of the grapevine precedes a full discussion of the developmental and environmental physiology of these fascinating and economically important plants. The concluding chapter considers the potential for genetic improvement of grapevines and includes coverage of the problems encountered, and the methods and strategies employed in breeding for scions and rootstocks.

Book Synopsis In Vitro Culture of Trees by : J.M. Bonga
Download or read book In Vitro Culture of Trees written by J.M. Bonga and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Woody plants provide many challenges to the tissue culturist. Although there are many excellent tissue culture books and manuals available, these are generally strongly biased towards herbacious crops. Consequently, they often do not pay sufficient attention to the problems that specifically apply to in vitro culture of tree species. Culture of the latter often poses problems which are either absent or of lesser significance when culturing herbacious species. When trees in the field are used as explant source, the problems can be especially severe. For example, the physiological condition of the explants is difficult to control because of variation in weather and biotic factors. Furthermore, it is often difficult to obtain explants free of contaminants from field grown trees. Lack of genetic uniformity and maturation are additional problems one often has to deal with when culturing tree cells or tissues. These problems are emphasized in this text. In vitro culture of trees is not viewed in isolation. It is considered in conjunction with breeding, traditional cloning and other common tree improvement techniques. The text discusses theoretical as well as practical aspects of the in vitro culture of trees.
Book Synopsis Olive Propagation Manual by : Andrea Fabbri
Download or read book Olive Propagation Manual written by Andrea Fabbri and published by Landlinks Press. This book was released on 2004-04-01 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practical manual is an authoritative guide to olive propagation, providing extended information on seed germination, rooting of cuttings, grafting and micropropagation. The authors describe each topic in detail and discuss the relative advantages and disadvantages of each procedure. The Olive Propagation Manual has been developed to take into account the future demand for olive oil, which is expected to increase to three million tonnes annually over the next 10 years. Such volumes will require active farming programs and olive trees for new orchards and the replacement of olive trees in existing orchards. As the olive industry moves from traditional manual methods to mechanised operations, planting stock will need to be developed to meet future challenges. Varietal selection will need to be directed to clones that are early bearing, disease resistant, able to be mechanically harvested, and produce quality fruit and oil. Each of these issues are addressed throughout this book. The Olive Propagation Manual explores historical perspectives, traditional methods and state-of-the-art olive propagation including theoretical explanations and all practical aspects.

Book Synopsis Agrobacterium: From Biology to Biotechnology by : Tzvi Tzfira
Download or read book Agrobacterium: From Biology to Biotechnology written by Tzvi Tzfira and published by Springer Science & Business Media. This book was released on 2007-12-25 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agrobacterium is a plant pathogen which causes the “crown-gall” disease, a neoplastic growth that results from the transfer of a well-defined DNA segment (“transferred DNA”, or “T-DNA”) from the bacterial Ti (tumor-inducing) plasmid to the host cell, its integration into the host genome, and the expression of oncogenes contained on the T-DNA. The molecular machinery, needed for T-DNA generation and transport into the host cell and encoded by a series of chromosomal (chv) and Ti-plasmid virulence (vir) genes, has been the subject of numerous studies over the past several decades. Today, Agrobacterium is the tool of choice for plant genetic engineering with an ever expanding host range that includes many commercially important crops, flowers, and tree species. Furthermore, its recent application for the genetic transformation of non-plant species, from yeast to cultivated mushrooms and even to human cells, promises this bacterium a unique place in the future of biotechnological applications. The book is a comprehensive volume describing Agrobacterium's biology, interactions with host species, and uses for genetic engineering.

Book Synopsis Iron Nutrition in Soils and Plants by : Javier Abadía
Download or read book Iron Nutrition in Soils and Plants written by Javier Abadía and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iron is a major constituent of the earth crust. However, under alkaline conditions commonly found in arid and semi-arid environments iron becomes unavailable to plants. When plants are affected by a shortage of iron their leaves become yellow (chlorotic), and both plant growth and crop yield are reduced. The roots of plants affected by iron deficiency may develop a series of responses directed to improve iron uptake, such as increased proton excretion and iron reduction capabilities or excretion of iron chela tors called siderophores. Iron deficiency affects major crops worldwide, including some of major economic importance such as fruit trees and others. Correction of iron deficiency is usually implemented through costly application of synthetic chelates. Since these correction methods are very expensive, the competitivity of farmers is often reduced and iron deficiency may become a limiting factor for the maintenance, introduction or expansion of some crops. In spite of the many years devoted to the study of iron deficiency, the knowledge of iron deficiency in soils and plants is still fragmentary in many aspects. We have only incomplete information on the processes at the molecular level that make some plant species and cultivars unable to take and utilize iron from the soil, whereas other plants grow satisfactorily under the same conditions.
