This structural work
has been supplemented by so much classification as will serve to make clear the
relationships of different groups, and the principles upon which the
classification is based, as well as enable the student to recognize the commoner
types of the different groups as they are met with. The aim of this book is not,
however, merely the identification of plants.
Photosynthesis is one of the
most important reactions on Earth. It is a scientific field that is the topic of
many research groups. This book is aimed at providing the fundamental aspects of
photosynthesis, and the results collected from different research groups.
If we can gain understanding of how plants grow, then we may be
able to manipulate it to reduce both chemical fertilizer use and its
environmental impact without decreasing the yield. This book provides
information about the use of bio-agents, plant health, plant pathogen, property
of melanin, and the influence of rootstock and root growth. Major topics covered
are: The Use of Bio-Agents for Management of Potato Diseases, Plant Health, The
Organic Amendment Improve the Yield and Quality of Vegetable, Plant Pathogens,
Making Soil More Accessible to Plants, Coumarin&
In the chapters of this book, on the
identification of trees, the aim has been to bring before the student only such
characters and facts as shall help him to distinguish the tree readily during
all seasons of the year. Special stress is laid in each case on the most
striking peculiarities. Possible confusion with other trees of similar
appearance is prevented as far as possible through comparisons with trees of
like form or habit.
This book is
the result of several years 1 experience of the authors with the Intermediate
classes. A lot of time is usually wasted in giving instructions and notes to the
students as to the procedure of the day's work. The authors feel that this
humble attempt at systematizing the practical work of Intermediate classes, will
go a long way to remove this difficulty.
The purpose of this note is to to give the students a general idea
of the principles of the science, rather than a comprehensive survey of the
whole vegetable kingdom. In a short course of this nature it is impossible to
include examples of every group, and therefore those types have been selected
with which it is moat important that the student should become acquainted.
This book covers the following topics: Plant Societies, The Plant Body, Seeds and Germination, The Root — The Forms of
Roots, Function and Structure, The Stem — Kinds and Forms, Pruning and General
Structure, Leaves: Form, Position, Structure, Anatomy and Function or Work,
Gleaning edible plants from herbals, botanies, travel books, cultural
histories, and experiments in scientific farming, Edward Lewis Sturtevant
(1842-1898) complied notes for the largest and most accurate work on edible
plants, cultigents, and secondary food sources ever written. 2,897 species with
comments from over 560 ancient and modern sources virtually cover the entire
field. The range is from the oldest known foods, the mallow and asphodel,
through newcomers like the tomato and celery, to wild foods which become
important under certain circumstances.
