Micropropagation is a technology that has developed within the past 30 years. Earlier overviews of plant tissue culture have reviewed micropropagation as just one of many tissue culture procedures in use. Since the applications of this technology have multiplied so rapidly in recent years, we decided that a specific overview of the technology was now appropriate Our book begins with a review of the general principles of tissue culture as applied to micropropagation. This review is concise since the general topic has been covered in numerous other books and reviews. The basic principles of laboratory design and construction are summarized in the second chapter. Common problems encountered in micropropagation, both during and after culture, are examined in detail in four chapters. As micropropagation developed from a laboratory curiosity to a commercial industry, different considerations became important. These are discussed in two chapters. An attempt has been made to assess the current status of commercial production around the world. This has been difficult because commercial production figures are often closely guarded and little has been done to collect statistics on this growing industry. Applications to a broad range of crops are discussed in a series of chapters. These try to report the state of the art in each area, but since applications for some crops are much more advanced than for others, the focus of these chapters varies depending upon the progress that has been made.

Plant micropropagation is one of the most classical and widespread biotechnological tools used around the world. Undoubtedly, this technique brought quite important advances to our knowledge about morphological, physiological and developmental patterns of plants, to the progress of genetic breeding and to the establishment of the genetic engineering, among others. This technique is based on the in vitro farming of plant fragments in an axenic environment, where all nutrients needed are kindly provided to the cultivated plant, which is maintained under controlled temperature and light-darkness periods. Although it can be considered an established technique, several advances have been integrated to the routines of micropropagation laboratories each year, incorporated to the productive sector and to the academy. In Micropropagation: Methods and Effects, the authors aimed to shortly present some of these advances, as well as practical results of using this biotechnology towards the conservation of plant genetic resources. In seven chapters, methods employed for the micropropagation of different plant species, from agricultural cultures to tree species of the Brazilian Atlantic Forest and advances in techniques for explants disinfection and for analysis of stomata complexes, as well as the progresses related to the micropropagation of apple and the use of bioreactors are presented. The seven chapters of this book will contribute towards incorporating new ideas to the daily effort of each reader, reaching the basic requests of students, professors, researchers and even non-specialized readers.

Micropropagation has become a reliable and routine approach for large-scale rapid plant multiplication, which is based on plant cell, tissue and organ culture on well defined tissue culture media under aseptic conditions. A lot of research efforts are being made to develop and refine micropropagation methods and culture media for large-scale plant multiplication of several number of plant species. However, many forest and fruit tree species still remain recalcitrant to in vitro culture and require highly specific culture conditions for plant growth and development. The recent challenges on plant cell cycle regulation and the presented potential molecular mechanisms of recalcitrance are providing excellent background for understanding on totipotency and what is more development of micropropagation protocols. For large-scale in vitro plant production the important attributes are the quality, cost effectiveness, maintenance of genetic fidelity, and long-term storage. The need for appropriate in vitro plant regeneration methods for woody plants, including both forest and fruit trees, is still overwhelming in order to overcome problems facing micropropagation such as somaclonal variation, recalcitrant rooting, hyperhydricity, polyphenols, loss of material during hardening and quality of plant material. Moreover, micropropagation may be utilized, in basic research, in production of virus-free planting material, cryopreservation of endangered and elite woody species, applications in tree breeding and reforestation.

Thirty-four Populus biotechnology chapters, written by 85 authors, are comprised in 5 sections: 1) in vitro culture (micropropagation, somatic embryogenesis, protoplasts, somaclonal variation, and germplasm preservation); 2) transformation and foreign gene expression; 3) molecular biology (molecular/genetic characterization); 4) biotic and abiotic resistance (disease, insect, and pollution); and 5) biotechnological applications (wood properties, flowering, phytoremediation, breeding, commercialization, economics, and bioethics).

This volume covers recent advances in the vegetative propagation of woody plants by tissue culture. A wide range of topics relevant to micropropagation of woody plants are discussed by renowned international scientists. These include cellular contro of morphogenesis, light regimes in tissue culture, maturation and rejuvenation, synthetic seed, genetics of micropropagated plants, haploid embryogenesis, protoplast culture, and acclimatization of ex vitro woody plants. In addition to micropropagation of selected woody plants, both gymnosperms and angiosperms, this volume also includes in vitro genetic selection, strategic planning for application of biotechnology for genetics and breeding, and clonal options for woody plant improvement. A balanced view of both perspectives and limitations of woody plant micropropagation is presented.

This book provides comprehensive information on micropropagation of economically important forest and fruit trees, which is usually available in scattered literature. Topics cover a wide range, from tropical forest and fruit trees for paper or food supply, to Prunus species for local craft bark production.

This greatly expanded and updated edition of a classic reference work comprises two volumes offering a compendium of methods for multiplying orchids through micropropagation. A detailed collection of procedures and methods for multiplying orchids, including organ, tissue, and cell culture techniques in vitro Presents classic techniques that have been in the forefront of orchid propagation since they were first developed in 1949 Detailed procedures are appended with tables and complete recipes for a large number of culture media Includes many illustrations, chemical formulas, historical vignettes, and seldom seen illustrations of people, orchids, apparatus and tools “… an excellent resource like its predecessor, …both informative and captivating, and served as a reminder of why we go to such extremes in our quest to propagate these plants.” American Orchid Society, 2009 “…in the sense of its universal value and importance, this Second Edition will undoubtedly be considered a classic, if only because it will serve as a sole and invaluable resource on the subject.” Plant Science Bulletin, 2009
