This volume is a monograph of the 47 species of the Dulcamaroid clade of the large and diverse genus Solanum. Species in the group occur in North, Central and South America, and in Europe and Asia. The group is most species-rich in Peru and Brazil, and three of the component species, Solanum laxum of Brazil, Solanum seaforthianum of the Caribbean and and Solanum crispum of Chile are cultivated in many parts of the world. All species are illustrated and a distribution map of each is provided. All names are typified and nomenclatural and bibliographic details for all typifications presented. One new species from Ecuador is described. The monograph is the first complete taxonomic treatment of these species since the worldwide monograph of Solanum done by the French botanist Michel-Felix Dunal in 1852.
Potato is the most significant non-cereal crop. Much attention has been paid to this commercially important crop. The aim of this volume is to capture the recent advances made in improving potatoes using traditional breeding methods as well as genetic engineering technology. The book provides a critical appraisal of the state-of-the-art finding on
This vintage book is a complete guide to the tomato, being a treatise on history, benefits, common problems, growing, harvesting, marketing, and many other related aspects. Easy-to-digest and profusely illustrated, this vintage handbook is a wealth of timeless information, and will be of considerable utility to novice growers. Contents include: ”The Tomato is a Great Food and Drop Plant”, ”Choose the Soil and Feed The Plant”, ”The Best in Seed is None too Good”, ”Strong Plants for Early Maturity and Heavy Crop”, ”Good Culture Favours Good Returns”, ”To Train Them Up or Let Them Spread”, ”The Eternal Battle with Insects and Diseases”, etc. Many vintage books such as this are becoming increasingly rare and expensive. We are republishing ”The Tomato” now in an affordable, high-quality edition complete with a specially commissioned new introduction on growing vegetables.
Wild crop relatives are now playing a significant part in the elucidation and improvement of the genomes of their cultivated counterparts. This work includes comprehensive examinations of the status, origin, distribution, morphology, cytology, genetic diversity and available genetic and genomic resources of numerous wild crop relatives, as well as of their evolution and phylogenetic relationship. Further topics include their role as model plants, genetic erosion and conservation efforts, and their domestication for the purposes of bioenergy, phytomedicines, nutraceuticals and phytoremediation. Wild Crop Relatives: Genomic and Breeding Resources comprises 10 volumes on Cereals, Millets and Grasses, Oilseeds, Legume Crops and Forages, Vegetables, Temperate Fruits, Tropical and Subtropical Fruits, Industrial Crops, Plantation and Ornamental Crops, and Forest Trees. It contains 125 chapters written by nearly 400 well-known authors from about 40 countries.
Principles of Soil and Plant Water Relations, 2e describes the principles of water relations within soils, followed by the uptake of water and its subsequent movement throughout and from the plant body. This is presented as a progressive series of physical and biological interrelations, even though each topic is treated in detail on its own. The book also describes equipment used to measure water in the soil-plant-atmosphere system. At the end of each chapter is a biography of a scientist whose principles are discussed in the chapter. In addition to new information on the concept of celestial time, this new edition also includes new chapters on methods to determine sap flow in plants dual-probe heat-pulse technique to monitor water in the root zone. - Provides the necessary understanding to address advancing problems in water availability for meeting ecological requirements at local, regional and global scales - Covers plant anatomy: an essential component to understanding soil and plant water relations
Mr. Faulkner’s masterpiece is recognized as the most important challenge to agricultural orthodoxy that has been advanced in this century. Its new philosophy of the soil, based on proven principles and completely opposed to age-old concepts, has had a strong impact upon theories of cultivation around the world. It was on July 5, 1943, when Plowman’s Folly was first issued, that the author startled a lethargic public, long bemused by the apparently insoluble problem of soil depletion, by saying, simply, “The fact is that no one has ever advanced a scientific reason for plowing.” With the key sentence, he opened a new era.For generations, our reasoning about the management of the soil has rested upon the use of the moldboard plow. Mr. Faulkner proved rather conclusively that soil impoverishment, erosion, decreasing crop yields, and many of the adverse effects following droughts or periods of excessive rainfall could be traced directly to the practice of plowing natural fertilizers deep into the soil. Through his own test-plot and field-scale experiments, in which he prepared the soil with a disk harrow, in emulation of nature’s way on the forest floor and in the natural meadow, by incorporating green manures into its surface, he transformed ordinary, even inferior, soils into extremely productive, high-yield croplands.Time magazine called this concept “one of the most revolutionary ideas in agriculture history.” The volume is being made available again not only because farmers, ranchers, gardeners, and agriculturists demanded it, but also because it details the kind of “revolution” which will aid those searching for the fruits of the earth in the emerging nations.
This paper provides guidelines for new high-throughput screening methods – both phenotypic and genotypic – to enable the detection of rare mutant traits, and reviews techniques for increasing the efficiency of crop mutation breeding.
It is over 20 years since the publication of A.c. Hulme's two volume text on The Biochemistry of Fruits and thei.r Products. Whilst the bulk of the information contained in that text is still relevant it is true to say that our understanding of the biochemical and genetic mech
Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.
