Description : Experiments which in previous years were made with ornamental plants have already afforded evidence that the hybrids, as a rule, are not exactly intermediate between the parental species. With some of the more striking characters, those, for instance, which relate to the form and size of the leaves, the pubescence of the several parts, etc., the intermediate, indeed, is nearly always to be seen; in other cases, however, one of the two parental characters is so preponderant that it is difficult, or quite impossible, to detect the other in the hybrid. from 4. The Forms of the Hybrid One of the most influential and important scientific works ever written, the 1865 paper Experiments in Plant Hybridisation was all but ignored in its day, and its author, Austrian priest and scientist GREGOR JOHANN MENDEL (18221884), died before seeing the dramatic long-term impact of his work, which was rediscovered at the turn of the 20th century and is now considered foundational to modern genetics. A simple, eloquent description of his 18561863 study of the inheritance of traits in pea plantsMendel analyzed 29,000 of themthis is essential reading for biology students and readers of science history. Cosimo presents this compact edition from the 1909 translation by British geneticist WILLIAM BATESON (18611926).

Description : Mendel's groundbreaking paper, which laid the foundation for further research upon heritage and genetics, is published here complete with the original illustrations and charts. When Mendel released this paper in 1865, it was after years of rigorous study and comparison in plant specimens and their offspring. His conclusion that variant traits were hereditary and could be determined, with a good degree of accuracy, through probability analysis were revolutionary in natural science at the time. Mendel's assertions regarding acquired characteristics, demonstrated through the comparison of peas and their seeds, would spark great interest in the nature and mechanisms behind heredity between generations of organisms. Seeking to gain high quality results, Mendel prefaces his explanations by noting that he artificially fertilized the plants described in the work.
Description : Mendel's 1865 paper, Experiments in Plant Hybridization, remained neglected till Bateson revived interest in Mendel's studies with this 1902 work, which helped lay the groundwork for the field of genetics. 8-page color insert.
Description : The second edition of Experiments in Plant Tissue Culture makes available new information that has resulted from recent advances in the applications of plant tissue culture techniques to agriculture and industry. This comprehensive laboratory text takes the reader through a graded series of experimental protocols and also provides an introductory review of each topic. Topics include: a plant tissue culture laboratory, aseptic techniques, nutritional components of media, callus induction, organ formation, xylem cell differentiation, root cultures, cell suspensions, micropropagation, embryogenesis, isolation and fusion of protoplasts, haploid cultures, storage of plant genetic resources, secondary metabolite production, and quantification of procedures. This volume offers all of the basic experimental methods for the major research areas of plant tissue culture, and it will be invaluable to undergraduates and research investigators in the plant sciences.
