Available in PDF, EPUB and Kindle. Book excerpt: 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The recently discovered plant hormone – strigolactones – and their contribution of apical dominance that has suddenly outdated dogma on apical dominance control Chapter summaries added Key literature references missed in the first edition as well as references to research completed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

This book was released on 2021 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dormancy and cold hardiness are critical adaptations for temperate woody perennial species to survive winter freezing stress. Grapevine (Vitis spp.) buds avoid freeze injury by supercooling water in their buds, which is a seasonally dynamic process and is related to dormancy mechanisms. There is high variability in traits related to dormancy and cold hardiness across grapevine species. Grapevine breeders have developed interspecific hybrid grapevine cultivars that combine desirable fruit quality and cold hardiness traits. These hybrids, referred to as cold-climate cultivars, have propelled the expansion of grapevine production into regions that were previously limited by annual low temperatures. However, cold-climate cultivars are still susceptible to freeze injury. Moreover, climate change predictions indicate new winter challenges, such as erratic and extreme weather events and generally warmer winter weather. Therefore, more information regarding cold hardiness and dormancy traits in cold-climate cultivars is needed. The research targeted in this dissertation aimed to characterize important dormancy and cold hardiness traits in five cold-climate cultivars.The lower temperature limit for bud cold hardiness changes across the seasons. Continuous, time-series cold hardiness data were collected to establish a foundation for cold hardiness abilities in individual cold-climate cultivars. The research presented in Chapter 2 characterized changes in bud cold hardiness for five cold-climate cultivars to identify relative risk for freeze injury throughout the dormant period and the factors regulating cold hardiness changes. This research also optimized and evaluated a bud cold hardiness prediction model for the same cultivars grown in a cold-climate region. We determined ambient temperature is the most important factor that regulates hybrid grapevine cold hardiness changes, and cultivars respond to temperature signals at varying degrees. We also calculated highly accurate cold hardiness predictions after reparametrizing a prediction model for each cold-climate cultivar. This information can guide cultivar selection decisions for particular growing regions and provides a framework for future studies concerning the physiological and mechanistic processes of grapevine cold hardiness. In addition, this work can strengthen decision making for improved bud cold hardiness protection, especially in cold-climate growing regions. The loss of cold hardiness i.e., deacclimation during spring is one of the most critical causes of freeze injury and is a determinant of budbreak phenology. Research presented in Chapter 3 evaluated the effect of chill unit accumulation and ambient temperature on dormancy status, deacclimation responses, and budbreak in five cold-climate cultivars grown in a cold climate region. In addition, this research validated a method for quantifying the contribution of chill unit accumulation to dormancy transitions. We observed deacclimation responses that increased continuously as chill units accumulated. This continuum of deacclimation responses was quantified as a rate ratio, referred to as deacclimation potential. Deacclimation potential provides an advantageous alternative method to assess dormancy status by quantifying a bud growth phenotype that is linked to growth but proceeds externally visible bud enlargement/elongation. We also observed a logistic trend between deacclimation rates and ambient temperature, referred to as the relative thermal contribution. Within an optimal temperature range, higher temperatures triggered higher deacclimation rates. However, changes in temperature have diminishing effects on deacclimation rates above and below that optimal range. Furthermore, deacclimation occurred at low temperatures, as low as 0°C. Relative thermal contribution can inform adjustments to base temperatures and patterns of temperature effects in models predicting phenological development and cold hardiness changes, especially for species that deacclimate at low temperatures. Finally, the effects of both chill unit accumulation and ambient temperature were combined in a predictive model that accurately describes deacclimation kinetics across the dormant period. Prolonged exposure to chilling temperature is needed to overcome endodormancy and the duration of endodormancy can be quantified as a chilling requirement. Research presented in Chapter 4 evaluated freezing temperature contribution towards endodormancy completion and aimed to determine chilling requirements for five cold-climate cultivars. We suspect freezing temperatures were effective in promoting endodormancy completion for hybrid grapevine cultivars. Therefore, chill models will need to be adapted to include freezing temperatures for more accurate estimation of chill requirements. Furthermore, we observed budbreak at a similar number of days and within the endodormancy threshold for buds exposed to different chill treatments, while their cold hardiness levels differed by approximately twofold. Cultivar-specific chilling requirements reported in this study do not represent an absolute chill requirement that is transferrable across regions or from year-to-year. Instead, estimated chill requirements likely represent a combination of traits involved in both dormancy status and deacclimation capacity. Therefore, future research that characterizes endodormancy completion should complement bud forcing assays with cold hardiness evaluation and/or deacclimation potential to verify dormancy status interpretations.
