Digital color analysis has become an increasingly popular and cost-effective method utilized by resource managers and scientists for evaluating foliar nutrition and health in response to environmental stresses. We developed and tested a new method of digital image analysis that uses Scion Image or NIH image public domain software to quantify leaf color. This publication provides instructions for using this software to measure the percentage green and red in leaves, colors of particular importance for the assessment of plant health. Comparisons of results from digital analyses of 326 scanned images of leaves and concurrent spectrophotometric measures of chlorophyll a, chlorophyll b, and anthocyanins verify that image analysis provides a reliable quantitative measure of leaf color and the relative concentrations of underlying plant pigments.

The application of imaging techniques in plant and agricultural sciences had previously been confined to images obtained through remote sensing techniques. Technological advancements now allow image analysis for the nondestructive and objective evaluation of biological objects. This has opened a new window in the field of plant science. Plant Image

What is computer graphics and what are the conceptual tasks of research in this area? To the average person the term still conveys more or less the design of - gos and the manipulation of pictures with the help of image-editing programs. However, during the past four decades, computer graphics has evolved into an innovative multifaceted ?eld of research and computing that affects many other sciences. In many areas and for many problems we can best convey an und- standing through images that trigger our sense with the highest capability: our eye. And, what is more, aside from algorithms, formulas, and tables, the c- puter graphics scientist often is able to create beauty. Though it is a beauty of its own, it often fascinates the viewer, especially when complex aesthetic images emerge from simple mathematical concepts. Also, there are only a few other areas that advance as dynamically as inf- matics and especially computer graphics. While CPU capacity still increases and is almost doubled every 18 months, the rendering speed and ef?ciency of graphics boards has increased even more during recent years. Today, images can be rendered in real time that some years ago still required several hours of computing. Parallel to the rapid improvement of computer hardware, many newalgorithms weredevelopedthattoday form the basis for some fundamental changes and achievements in graphics.

The 10th IAPTC&B Congress, Plant Biotechnology 2002 and Beyond, was held June 23-28, 2002, at Disney's Coronado Springs Resort, in Orlando, Florida, USA. It was attended by 1,176 scientists from 54 countries. The best and brightest stars of international plant biotechnology headlined the scientific program. It included the opening address by the President of the IAPTC&B, 14 plenary lectures, and 111 keynote lectures and contributed papers presented in 17 symposia covering all aspects of plant biotechnology. More than 500 posters supplemented the formal program. The distinguished speakers described, discussed and debated not only the best of science that has been done or is being done, but also how the power of plant biotechnology can be harnessed to meet future challenges and needs. The program was focused on what is new and what is exciting, what is state of the art, and what is on the cutting edge of science and technology. In keeping with the international mandate of the IAPTC&B, 73 of the 125 speakers were from outside the United States, representing 27 countries from every region of the world. The 10th IAPTC&B Congress was a truly world-class event. The IAPTC&B, founded in 1963 at the first international conference of plant tissue culture organized by Philip White in the United States, currently has over 1,500 members in 85 countries. It is the largest, oldest, and the most comprehensive international professional organization in the field of plant biotechnology. The IAPTC&B has served the plant biotechnology community well through its many active national chapters throughout the World, by maintaining and disseminating a membership list and a website, by the publication of an official journal (formerly the Newsletter), and by organizing quadrennial international congresses in France (1970), the United Kingdom (1974), Canada (1978), Japan (1982), the United States (1963, 1986, 2002), The Netherlands (1990), Italy (1994), and Israel (1998). In addition, the IAPTC&B has a long tradition of publishing the proceedings of its congresses. Individually, these volumes have provided authoritative quadrennial reports of the status of international plant biotechnology. Collectively, they document the history of plant biotechnology during the 20th century. They are indeed a valuable resource. We are pleased to continue this tradition by publishing this proceedings volume of the 10th IAPTC&B Congress. Regrettably, we are not able to publish seven of the lectures in full (only their abstracts are included). The American and Canadian chapters of the IAPTC&B, the Plant Section of the Society for In Vitro Biology, and the University of Florida hosted the 10th IAPTC&B Congress. The Congress was a true partnership between academia and industry, and was generously supported by both groups (see list of donors/sponsors on back cover). A number of prominent international biotechnology companies and publishers participated in the very successful Science and Technology Exhibit (see accompanying list of exhibitors) The IAPTC&B awarded 84 fellowships to young scientists from 31 countries (see accompanying list of fellowship recipients) to support their participation in the Congress.

This volume provides informative research on the scientific evidence of the health benefits that can be derived from medicinal plants and how their efficacies can be improved. It is divided into three sections that cover the phytochemistry of medicinal plants, disease management with medicinal plants, and novel research techniques in medicinal plants. The pharmacological benefits of several specific plants are discussed, addressing health issues such as metabolic and mental disorders, acute mountain sickness, polycystic ovarian syndrome, and specific diseases such as Huntington’s. It also looks at the role of antioxidants in disease management. Additionally, the book covers recent problems of drug resistance and how medicinal plants can serve as antibiotic, anthelmintic, and antiparasitic drugs that will be helpful for human and animals.

& Quot;Plant Sciences Reviews 2011" provides scientists and students in the field with timely analysis on key topics in current research. Originally published online in CAB Reviews, this volume makes available in printed form the reviews in plant sciences published during 2011.

Identification of desirable genotypes with traits of interest is discernible for making genetic improvement of crop plants. In this direction, screening of a large number of germplasm for desirable traits and transfer of identified traits into agronomic backgrounds through recombination breeding is the common breeding approach. Although visual screening is easier for qualitative traits, its use is not much effective for quantitative traits and also for those, which are difficult to score visually. Therefore, it is imperative to phenotype the germplasm accessions and breeding materials precisely using high throughput phenomics tools for challenging and complex traits under natural, controlled and harsh environmental conditions. Realizing the importance of phenotyping data towards identification and utilization of a germplasm as donors, global scientific community has exerted increased focus on advancing phenomics in crop plants leading to development of a number of techniques and methodologies for screening of agronomic, physiological, and biochemical traits. These technologies have now become much advanced and entered the era of digital science. This book provides exhaustive information on various aspects related to phenotyping of crop plants and offers a most comprehensive reference on the developments made in traditional and high throughput phenotyping of agricultural crops.
