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.

Book excerpt: The domestication of grapes dates back five thousand years ago and has spread to nearly all continents. In recent years, grape acreage has increased dramatically in new regions, including the United States of America, Chile, Asia (China and India), and Turkey. A major limiting factor to the sustained production of premium grapes and wines is infections by viruses. The advent of powerful molecular and metagenomics technologies, such as molecular cloning and next generation sequencing, allowed the discovery of new viruses from grapes. To date, grapevine is susceptible to 64 viruses that belong to highly diverse taxonomic groups. The most damaging diseases include: (1) infectious degeneration; (2) leafroll disease complex; and (3) rugose wood complex. Recently, two new disease syndromes have been recognized: Syrah decline and red blotch. Losses due to fanleaf degeneration are estimated at $1 billion annually in France alone. Other diseases including leafroll, rugose wood, Syrah de cline and red blotch can result in total crop loss several years post-infection. This situation is further exacerbated by mixed infections with multiple viruses and other biotic as well as adverse abiotic environmental conditions, such as drought and winter damage, causing even greater destruction. The book builds upon the last handbook (written over twenty years ago) on the part of diagnostics and extensively expands its scope by inclusion of molecular biology aspects of select viruses that are widespread and economically most important. This includes most current information on the biology, transmission, genome replication, transcription, subcellular localization, as well as virus-host interactions. It also touches on several novel areas of scientific inquiry. It also contains suggested directions for future research in the field of grapevine virology.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers about 20 grape species that are vitally important in breeding programs and provide information on approximately 150 of the most familiar grape rootstocks in the world. Today, grape rootstocks play a fundamental role in resistance to biotic and abiotic stresses and adaptation of grapevine to different environmental conditions, a factor that has opened commercial grape growing up to regions that might otherwise be overlooked. Grape rootstocks can be used for adaptation to a variety of soil conditions, including soil texture, depth, nutrient availability, pH, salinity, lime content, water availability (drought), and water drainage. Rootstocks can also be used to shift scion cultivar; the timing of various key phenological events and indirectly affects vineyard design. There are around 1500 grape rootstocks developed in the world, of which around 50 are commonly used as commercial rootstock. North American species account for around 30 species, and two-third of them have already been used for rootstock breeding at one time or another. However, the most commonly available rootstocks are derived from just three American species (V. berlandieri, V. rupestris, and V. riparia). Therefore, the most common grape rootstocks have a narrow genetic base, and efforts to extend the gene pools for breeding programs by using the other species are of ongoing importance to the industry and scientific community.

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.
