Anyone who observes fruit trees may wonder how or why they behave in specific ways. Some trees grow upright while others have a spreading habit. Some produce many flowers and small immature fruit only to drop most of the fruit later on; others grow more strongly on their sunny side than their shady side. It is common to ascribe such behavior to the tree as a whole and state that trees preferentially "allocate" resources to specific organs. However, this is the wrong approach to understanding tree functioning and behavior. Trees are not in control of what they do. What trees do and how they function is shaped by the individual organs that make up the tree, not by the tree as a whole. The genetic code only indirectly determines the habit, structure and behavior of a tree by defining the behavioral and functional limits of the component organs, tissues and cells. Unlike animals that have a mechanism for collective control of the whole organism - a central nervous system - trees (and plants in general) are more appropriately considered as collections of semi-autonomous organs. These organs are dependent on one another for resources, such as water, energy and nutrients, but control their own destiny. This book presents a clear set of integrative concepts for understanding the overall physiology and growth of temperate deciduous fruit trees. The emphasis is on overarching principles rather than detailed descriptions of tree physiology or differences among the numerous species of fruit trees. Although the focus is on deciduous fruit trees, many aspects apply to evergreen fruit trees and trees that grow naturally in unmanaged situations.

​Global climate change is expected to produce increased carbon dioxide levels in the atmosphere, higher temperatures, aberrant precipitation patterns and a host of other climatic changes that would affect all life on this planet. This review article addresses the impact of climate change on fruit trees and the response of the trees to a changing environment. The response of fruit trees to increasing carbon dioxide levels, phenological changes occurring in the trees themselves due to increased temperature and the lower chilling hours especially in the temperate regions, ecophysiological adaptations of the trees to the changing climate, impact of aberrant precipitation, etc. are reviewed. There is very little data on the impact of rising CO2 levels on fruit tree performance or productivity including the temperate region. Based on a large number of observations on the phenology, there is reason to believe that the flowering and fruiting of most species have advanced by quite a few days, but with variations in different crops and on different continents. The chilling hours have also grown shorter in many regions, causing considerable reductions in yield for several species. In the tropics, there is very little work on fruit trees; however, the available data show that precipitation is a major factor regulating their phenology and yield. The ecophysiological adaptations vary from species to species, and there is a need to develop phenological models in order to estimate the impact of climate change on plant development in different regions of the world. More research is also called for to develop adaptation strategies to circumvent the negative impacts of climate change.

Horticultural sector presents many opportunities for economic development and improving livelihood of growers but several factors constrain production and limit the potential for trade of fruits and vegetables. Tephritid fruit flies constitute a major constraint. They cause enormous losses through direct feeding damage and loss of market opportunities through imposition of quarantine restrictions by importing countries to prevent entry and their establishment. In Africa, several native (Ceratitis and Dacus spp) and exotic (Bactrocera and Zeugodacus spp.) species inflict considerable losses to horticulture causing losses ranging from 30-90%. Over the past 10 years of R&D, extensive information has been generated on bioecology and management of several native and exotic fruit flies in Africa. While several specific reviews have addressed various aspects of the biology, ecology and management of economically important tephritid fruit flies; coverage of African native species has been limited largely to Bactrocera oleae and Ceratitis capitata – which are not economically important species in many Africa countries. Indeed, no book exist that have explicitly addressed economically important African fruit flies and none of the various reviews, have specifically focused on the status of the bioecology, economic impact and management of exotic and native fruit flies – including several potentially invasive Dacus species attacking vegetables - in Africa. This book consolidates this status of knowledge and socio-economic impact of various intervention techniques that are currently being applied across Africa. The timing of the book is especially pertinent due to the changing fruit fly landscape in Africa – caused by arrivals of the highly destructive alien invasives (Bactrocera dorsalis, B. zonata, and B. latifrons) - and the priorities African countries have placed recently on export of fruits and vegetables to international markets. This is an important reference material for researchers, academics and students that are keen at improving horticulture and enhancing food and nutrition security in Africa and beyond.

Developed especially for use by backyard orchardists, rare fruit growers, and small-scale growers, The Home Orchard offers a comprehensive look at standard growing methods, as well as some innovative practices that enthusiasts have developed in recent years, some of which are uniquely suited to the small-scale grower. You will learn how trees grow, which species grow best in the different regions and soils, varieties from which to select, preparing the soil, planting, watering and fertilizing, pruning and grafting, thinning the fruit, diagnosing problems, controlling pests, and harvesting. You'll also find special attention given to organic and non-toxic pest management and fertilization methods. Key pests and diseases are identified and natural control methods are emphasized. Irrigation methods for the backyard grower are discussed and the difficult task of how often and how much water to apply is simplified. The focus is on giving the trees enough water but doing so in an efficient, water-saving manner. Included are hundreds of photographs and diagrams that clearly show how to produce the best crops. Photos of several practices, such as key budding and grafting methods, are depicted in step-by-step photos. No other publication provides this breadth and depth of coverage --

Farmers have developed a range of agricultural practices to sustainably use and maintain a wide diversity of crop species in many parts of the world. This book documents good practices innovated by farmers and collects key reviews on good practices from global experts, not only from the case study countries but also from Brazil, China and other parts of Asia and Latin America. A good practice for diversity is defined as a system, organization or process that, over time and space, maintains, enhances and creates crop genetic diversity, and ensures its availability to and from farmers and other users. Drawing on experiences from a UNEP-GEF project on "Conservation and Sustainable Use of Wild and Cultivated Tropical Fruit Tree Diversity for Promoting Livelihoods, Food Security and Ecosystem Services", with case studies from India, Indonesia, Malaysia and Thailand, the authors show how methods for identifying good practices are still evolving and challenges in scaling-up remain. They identify key principles effective as a strategy for mainstreaming good practice into development efforts. Few books draw principles and lessons learned from good practices. This book fills this gap by combining good practices from the research project on tropical fruit trees with chapters from external experts to broaden its scope and relevance.

"A comprehensive and entertaining historical and botanical review, providing an enjoyable and cognitive read.”—Nature The foods we eat have a deep and often surprising past. From almonds and apples to tea and rice, many foods that we consume today have histories that can be traced out of prehistoric Central Asia along the tracks of the Silk Road to kitchens in Europe, America, China, and elsewhere in East Asia. The exchange of goods, ideas, cultural practices, and genes along these ancient routes extends back five thousand years, and organized trade along the Silk Road dates to at least Han Dynasty China in the second century BC. Balancing a broad array of archaeological, botanical, and historical evidence, Fruit from the Sands presents the fascinating story of the origins and spread of agriculture across Inner Asia and into Europe and East Asia. Through the preserved remains of plants found in archaeological sites, Robert N. Spengler III identifies the regions where our most familiar crops were domesticated and follows their routes as people carried them around the world. With vivid examples, Fruit from the Sands explores how the foods we eat have shaped the course of human history and transformed cuisines all over the globe.
