  • A leading text for undergraduate- and graduate-level courses, this book introduces widely used forms of remote sensing imagery and their applications in plant sciences, hydrology, earth sciences, and land use analysis. The text provides comprehensive coverage of principal topics and serves as a framework for organizing the vast amount of remote sensing information available on the Web. Including case studies and review questions, the book's four sections and 21 chapters are carefully designed as independent units that instructors can select from as needed for their courses.

  • The primary objective of the ebook is to deliver a thoughtful combination of viewpoints which will be valuable to workers in all places of plant sciences. The material included in this ebook will be important in building methods to counter water anxiety in crops. Vegetation encounter drinking water anxiety both when the h2o provide to their roots becomes limiting, or when the transpiration rate gets to be intense. H2o stress is primarily caused by a h2o deficit, this sort of as a drought or higher soil salinity....

  • Plants are sessile organisms and as such must have mechanisms to deal with both abiotic and biotic stresses to ensure survival. The term “abiotic stress” includes many stresses caused by environmental conditions such as drought, salinity, UV and extreme temperatures. Due to global climate change it is predicted that abiotic stresses will increase in the near future and have substantial impacts on crop yields (Intergovernmental Panel of Climate Change; http://www.ipcc.ch).

  • The study of wetland plants has been of interest to botanists for many years, but the need to identify and understand these plants has expanded dramatically since the 1970s. At that time, ecologists began to make known the vital role that wetlands play in our landscapes. The image of wetlands has shifted from that of mosquito-ridden wastelands to natural areas of critical importance. Because the field of wetland ecology has expanded, so has the study of the plants that thrive there, and their role in ecosystem dynamics.

  • To properly operate a waterworks or wastewater treatment plant and to pass the examination for a waterworks/wastewater operator’s license, it is necessary to know how to perform certain calculations. In reality, most of the calculations that operators at the lower level of licensure need to know how to perform are not difÞcult, but all operators need a basic understanding of arithmetic and problem-solving techniques to be able to solve the problems they typically encounter.

  • It is my privilege to contribute the foreword for this unique volume entitled: “Plant Tissue Culture Engineering,” edited by S. Dutta Gupta and Y. Ibaraki. While there have been a number of volumes published regarding the basic methods and applications of plant tissue and cell culture technologies, and even considerable attention provided to bioreactor design, relatively little attention has been afforded to the engineering principles that have emerged as critical contributions to the commercial applications of plant biotechnologies.

  • When the price of Ginseng advanced some years ago hundreds engaged in the business who knew little or nothing of farming, plant raising and horticulture. That they largely failed is not to be wondered at. Later many began in a small way and succeeded. Many of these were farmers and gardeners. Others were men who had hunted, trapped and gathered "seng" from boyhood. They therefore knew something of the peculiarities of Ginseng. It is from the experience of these men that this work is largely made up--writings of those who are in the business.
