Book Description
The Science of Grapevines: Anatomy and Physiology is an introduction to the physical structure of the grapevine, its various organs, their functions and their interactions with the environment. Beginning with a brief overview of the botanical classification (including an introduction to the concepts of species, cultivars, clones, and rootstocks), plant morphology and anatomy, and growth cycles of grapevines, The Science of Grapevines covers the basic concepts in growth and development, water relations, photosynthesis and respiration, mineral uptake and utilization, and carbon partitioning. These concepts are put to use to understand plant-environment interactions including canopy dynamics, yield formation, and fruit composition, and concludes with an introduction to stress physiology, including water stress (drought and flooding), nutrient deficiency and excess, extreme temperatures (heat and cold), and the impact and response to of other organisms. Based on the author's years of teaching grapevine anatomy as well as his research experience with grapevines and practical experience growing grapes, this book provides an important guide to understanding the entire plant. - Chapter 7 broken into two chapters, now "Environmental Constraints and Stress Physiology and Chapter 8 "Living with Other Organisms" to better reflect specific concepts - Integration of new research results including: - Latest research on implementing drip irrigation to maximize sugar accumulation within grapes - Effect of drought stress on grapevine's hydraulic system and options for optimum plant maintenance in drought conditions - The recently discovered plant hormone – strigolactones – and their contribution of apical dominance that has suddenly outdated dogma on apical dominance control - Chapter summaries added - Key literature references missed in the first edition as well as references to research completed since the 1e publication will be added

Book Description
Part 1: Calibration models are important for the use of Spanner-type psychrometers, but they have not been adequately evaluated. A non-zero intercept in the regression between psychrometric electrical output (EO) and water potential (WP) is commonly observed, but incompatible with the temperature correction factor (TCF) model, most often used to account for the temperature-dependence of the EO/WP relation. Calibration errors (mean absolute [predicted-observed] WP) for 10 commercial, in-situ, temperature-compensated psychrometers, were compared over a temperature and WP range of 10-40°C and -2.5 to 0 MPa, respectively, using the current commercial TCF model, a modified TCF model, two empirical models, and a mechanistic model. For TCF models, a psychrometer-specific, linear, EO/WP relation was determined at 25°C, but models differed in whether extrapolation to other temperatures was based only on the 25°C data or on data obtained at all temperatures, and whether model parameters were determined for each psychrometer (individual-fit) or all psychrometers (group-fit). Measurement error was estimated at 0.042 MPa, and only the individual-fit modified TCF model exhibited an error (0.048 MPa) which was not statistically different from the measurement error. Individual-fit errors for other models ranged from 0.058 to 0.100 MPa. Group-fit errors ranged from 0.067 (current commercial TCF) to 0.109 MPa, with very little difference among models, indicating the current commercial model as adequate for a group-fit approach. Part 2: The hydraulic connection between the grape (Vitis vinifera ‘Chardonnay’) berry and the parent vine generally decreases over berry development between pre- and post-veraison, and it is important for understanding the response of berry size and expansive growth to changes in vine water status. However, the reported pathway hydraulic conductance (estimated using excised samples) varied greatly and spanned over one order of magnitude. In addition, it is unclear where the decrease of hydraulic connection occurs along the water transport pathway between the berry and the parent vine. This study aims to: 1) estimate the pathway hydraulic conductance in situ, and 2) locate the site responsible for the decrease of hydraulic connection in situ. We manipulated the stem water potential (SWP) of a grapevine by drying, root pressurization/depressurization, and re-watering, and measured the responses of berry diameter and the turgor of pedicel cortical cells (as an indicator of pedicel water status) in situ. The in situ estimated hydraulic conductance of the water transport pathway between the vine and the berry decreased by about 90% from pre- to post-veraison. The hydraulic conductance at post-veraison was similar to the low conductance values reported in previous literature. Changes in pedicel cortical cell turgor were positively correlated with changes in SWP both at pre-veraison and post-veraison without a significant difference. This result indicates that the site responsible for the pre- to post-veraison decrease of berry hydraulic connection to the parent plant resided at a local scale, between the pedicel and the berry itself.

Book Description
Grapevine is one of the most widely cultivated plant species worldwide. With the publication of the grapevine genome sequence in 2007, a new horizon in grapevine research has unfolded. Thus, we felt that a new edition of ‘Molecular Biology & Biotechnology of the Grapevine’ could expand on all the latest scientific developments. In this edition and with the aid of 73 scientists from 15 countries, ten chapters describe new aspects of Grapevine Molecular Physiology and Biotechnology and eleven chapters have been revised and updated. This book is intended to be a reference book for researchers, scientists and biotechnological companies, who want to be updated in viticultural research, but also it can be used as a textbook for graduate and undergraduate students, who are interested in the Molecular Biology and Biotechnology of Plants with an emphasis on the Grapevine.

Book Description
The global demand for high quality fruits that are rich in nutrients and that can endure the demands of worldwide supply chains is growing rapidly. Fruits are an important component of the human diet, providing vitamins, minerals, antioxidants, and fiber. All of these qualities contribute to the nutritional needs and health maintenance of humans. Breeding for Fruit Quality reviews the application of modern plant breeding methods to the development of improved varieties of fruits. Breeding for Fruit Quality opens with chapters that look at fruit biology and breeding strategies behind specific traits, including a look at traits such as organoleptic quality, nutritional value, and improved yield, among others. Subsequent chapters review breeding efforts to improve overall quality in a wide range of specific fruits. Providing broad ranging coverage of cutting edge methods now being applied to the development of fruit crops, Breeding for Fruit Quality will be a valuable resource for fruit biologists, breeders, geneticists, and industry personnel. Key Features: Broad coverage of modern breeding technologies being implemented to improve overall fruit quality Trait specific chapters explore efforts to promote traits of industrial and nutritional importance Chapters in fruits, ranging from apple and grapes to tomatoes and olives, provide detailed coverage of breeding practices for economically important fruit crops
