Experimental Plant Physiology Classic Reprint

Excerpt from Experimental Plant Physiology The appreciation shown toward the translation of Oels' Pflanzenphysiologische Versuche prepared by the present writer, together with the comments and suggestions from laboratories in which it has been used, has led to the preparation of this manual, which it is hoped will conform somewhat more nearly to the needs of American students. The general form of Oels' manual has been retained, and many cuts from the translation and a few paragraphs of the text have been repeated here without indication of their origin. Only the more important and better established portions of the subject are treated, and these in the manner already in general use. With the rapid advance of investigation it is next to impossible that an elementary' laboratory manual should include the latest results, especially when the essential points of many of them may yet be in controversy and need the critical treatment which is certainly not within the province of a work of this character. In the hands of an instructor in touch with current botanical thought, such deficiencies are easily supplied. In the interests of precision, the term "assimilation" is here used exclusively to denote a general function of protoplasm, while the term "photosynthesis," which was introduced into the translation of Oels' manual (Preface and page 30), is adopted to signify the special process of forming carbohydrates from carbon dioxide and water in the presence of chlorophyll and sunlight. The author is indebted to Mr. R. N. Day and Miss J. E. Tilden for the demonstration and drawing for Figure 32.

Excerpt from Experimental Plant Physiology: For Beginners The book is intended essentially as a guide to practical work, and every experiment should therefore be care fully worked through, not merely read. The best plan for a teacher to follow, in all physiological work, is to present a problem to the children, and encourage them to suggest the method by which it may be solved and to draw their own conclusions from the observations made.

Excerpt from A Laboratory Course in Plant Physiology: Especially as a Basis for Ecology If the present book is found to have any merit in its particular field, it will consist chiefly in its practicability. With but few and clearly indicated exceptions, everything recommended in it has been repeatedly tested and found effective both by my students and myself. The book is the resultant of six years of effort and experiment directed to this end with classes of from eight to twelve students. The illustrations of the experiments are in every case from photographs of experiments in successful operation. Such pictures, while inferior in clearness of detail and perhaps in artistic effect to good drawings, have at least this conspicuous merit, that they may be accepted and followed with perfect confidence. In developing the course and the experiments herein recommended, I have tried to utilize, and, naturally, to improve upon, the best work done by others in the same lines. Little account is taken in these pages of the exact appliances and methods with which the classical work of plant physiology has been done, for the investigation phases of the subject lie without the scope of this work, and they are, moreover, summarized admirably in Pfeffer's great Handbook. But all phases of plant physiology utilizable for purposes of general education are meant to be included.

Excerpt from A Text-Book of Plant Physiology I have purposely made no attempt to give directions for experiments, believing that a laboratory manual and a text book must meet such different needs that the style of the one is impossible for the other.. This book must, however, be supplemented by actual laboratory work by the reader, under the guidance of a teacher or of some of the laboratory manuals mentioned on page 27, or both.

Excerpt from Some Recent Researches in Plant Physiology The general aim of the book is to present to senior students and investigators the results of recent work in a few of those branches of plant physiology which are at present attracting attention. Matter already to be found in text books has been almost entirely excluded. In order to preserve to some extent a historical method of treatment, the date is inserted after the name of each worker, and is followed by a numeral to show to which paper reference is being made in cases where more than one were published in a year. By such a presentation of portions of the science which are still in a state of rapid growth, it is hoped that further investigation will be stimulated. The choice of material by the author was, to a considerable degree, influenced by his familiarity with certain subjects of general interest, portions of which are being studied experimentally by the staff of the School of Botany, Trinity College, Dublin. Upon these, rather than upon other researches of equal or greater importance, he has felt qualified to write, on account of his first-hand knowledge of many of the methods employed. A small amount of hitherto unpublished work has also been included. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
