Modern Methods of Plant Analysis When the handbook Modern Methods ofPlant Analysis, was first introduced in 1954, the considerations were: 1. the dependence of scientific progress in biologyon the improvement of existing and the introduction of new methods; 2. the difficulty in finding many new analytical methods in specialized journals which are normally not accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete, that it is difficult to reproduce experiments. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since there is still today a demand for the old series, the publisher has decided to resume publication of Modern Methods ofPlant Analysis.It is hoped that the NewSeries willbejust as acceptable to those working in plant sciences and related fields as the early volumes undoubtedlywere.It is difficult to single out the major reasons for the success of any publication, but we believe that the methods published in the first series were up-to-date at the time and presented in a waythat made description, as applied to plant material, complete in itselfwith little need to consult other publications. Contribution authors have attempted to follow these guidelines in this New Series of volumes. Editorial The earlier series of Modern Methods ofPlant Analysis was initiated by Michel V.
