The engineering of plants has a long history on this continent. Fields, forests, orchards, and prairies are the result of repeated campaigns by amateurs, tradesmen, and scientists to introduce desirable plants, both American and foreign, while preventing growth of alien riff-raff. These horticulturists coaxed plants along in new environments and, through grafting and hybridizing, created new varieties. Over the last 250 years, their activities transformed the American landscape. "Horticulture" may bring to mind white-glove garden clubs and genteel lectures about growing better roses. But Philip J. Pauly wants us to think of horticulturalists as pioneer "biotechnologists," hacking their plants to create a landscape that reflects their ambitions and ideals. Those standards have shaped the look of suburban neighborhoods, city parks, and the "native" produce available in our supermarkets. In telling the histories of Concord grapes and Japanese cherry trees, the problem of the prairie and the war on the Medfly, Pauly hopes to provide a new understanding of not only how horticulture shaped the vegetation around us, but how it influenced our experiences of the native, the naturalized, and the alien--and how better to manage the landscapes around us.
Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.
Wheat: Science and Trade is an up-to-date, comprehensive reference work designed to expand the current body of knowledge on this staple crop, incorporating new information made available by genetic advances, improvements in the understanding of wheat's biology, and changes in the wheat trade industry. Covering phylogeny and ontogeny, manipulation of the environment and optimal management, genetic improvement, and utilization and commercialization, the book focuses on the most economically significant diseases and impacts
Discussing the latest processes involved in researching yield generation, Wheat: Ecology and Physiology of Yield Determination will help you design various types of crop production systems for maximum yield. Featuring information on developing high-yielding, low-input, and quality-oriented systems, this book offers you both physiological and ecological approaches that will help you understand the crop as well as increase its production. Discussing aspects of wheat growth for specific regions around the world, Wheat provides you with information that will improve the size and quality of your crops, including: how temperature, vernalization, and the photoperiod affect the development of wheat using the correct amount of nitrogen fertilizers for wheat crops an explanation of the reproduction and nitrogen cycles of wheat how elements and conditions such as lipids, proteins, nitrogen, and climate enhance grain quality estimating and determining optimal sowing dates examining factors that may affect wheat yield-density relationships, such as planting arrangement and date of sowing preventing seed decay and examining effects of mildews and leaf blights examining historical trends of the crop to see what further research needs to be done You'll also receive information on the genetic gains in wheat research that are improving the physiological traits and numerical components of this essential grain. Within Wheat, you'll find data and methods from international experts in the field that will improve the yield and growth of the world's most important crop.
