Pulping and Papermaking of Non-wood Plant Fibres presents the
latest technologies associated with the papermaking process. With
chapters specific to each non-wood species, the book provides
step-by-step guidance on processes such as pulping, bleaching,
blending and beating. Non-wood fibers are practical for pulp and
paper production due to their chemical content of cellulose,
hemicellulose and lignin percentages. Beginning with a general
overview of non-wood fibers in the papermaking process, chapters
then take a deep dive into different raw materials and their
processes, including bamboo, corn stalk, pineapple leaves and
sugarcane. This book is an essential resource for researchers,
scientists and industry specialists.
Peatlands form important landscape elements in many parts of the
world and play significant roles for biodiversity and global carbon
balance. This new edition has been fully revised and updated,
documenting the latest advances in areas such as microbial
processes and relations between biological processes and hydrology.
As well as thoroughly referencing the latest research, the authors
expose a rich older literature where an immense repository of
natural history has accumulated. The Biology of Peatlands starts
with an overview of the main peatland types (marsh, swamp, fen, and
bog), before examining the entire range of biota present (microbes,
invertebrates, plants, and vertebrates), together with their
specific adaptations to peatland habitats. Detailed coverage is
devoted to the genus Sphagnum, the most important functional plant
group in northern peatlands, although tropical and southern
hemisphere peatlands are also covered. Throughout the book the
interactions between organisms and environmental conditions
(especially wetness, availability of oxygen, and pH) are
emphasized, with chapters on the physical and chemical
characteristics of peat, the role of peat as an archive of past
vegetation and climate, and peatland succession and development.
Several other key factors and processes are then examined,
including hydrology and nutrient cycling. The fascinating peatland
landforms in different parts of the world are described, together
with theories on how they have developed. Human interactions with
peatlands are considered in terms of management, conservation, and
restoration. A final chapter, new to this edition, focuses on the
role of peatlands as sources or sinks for the greenhouse gases
carbon dioxide and methane, and the influences of climate change on
peatlands. This timely and accessible text is suitable for students
and researchers of peatland ecology, as well as providing an
authoritative overview for professional ecologists and conservation
biologists.
Phytohormones and Stress Responsive Secondary Metabolites provides
a deep dive into the signaling pathways associated with
phytohormones and phytometabolites. With a strong focus on plant
stress responses and DNA technology, the book highlights plant
biotechnology and metabolic engineering principles. Biotechnology,
by using DNA editing technologies, allows the expression of plant
genes into other plant species with desirable modulation on plant
behavior. Beginning with an overview of phytohormone signaling,
growth and abiotic and biotic stresses, subsequent chapters explore
DNA modification strategies, epigenetic and epigenomic regulation,
and miRNA regulation. This book will be an essential resource for
students, researchers and agriculturalists interested in plant
physiology, plant genetics and plant biotechnology.
Hormonal Cross-Talk, Plant Defense and Development: Plant Biology,
Sustainability and Climate Change focuses specifically on plants
and their interaction to auxins, gibberellins, cytokinins,
ethylene, abscisic acid, jasmonates, brassinosteroids,
strigolactones, and the potential those interactions offer for
improved plant health and production. Plant hormones (auxins,
gibberellins, cytokinins, ethylene, abscisic acid, jasmonates,
brassinosteroids, salicylic acid, strigolactones etc.) regulate
numerous aspects of plant growth and developmental processes. Each
hormone initiates a specific molecular pathway, with each pathway
integrated in a complex network of synergistic, antagonistic and
additive interactions. This is a valuable reference for those
seeking to understand and improve plant health using natural
processes. The cross-talks of auxins - abscisic acid, auxins -
brassinosteroids, brassinosteroids- abscisic acid, ethylene -
abscisic acid, brassinosteroids - ethylene, cytokinins - abscisic
acid, brassinosteroids - jasmonates, brassinosteroids - salicylic
acid, and gibberellins - jasmonates - strigolactones have been
shown to regulate a number of biological processes in plant system.
The cross-talk provides robustness to the plant immune system but
also drives specificity of induced defense responses against the
plethora of biotic and abiotic interactions.
The Role of Gasotransmitters In the Amelioration of Arsenic
Toxicity in Plants: Biology and Biotechnology, in the Plant
Gasotransmitter series, provides research on how gasotransmitters
can reduce the stress faced by plants through arsenic
contamination. With a strong focus on metabolic processes, the book
presents the various pathways and mechanisms associated with
gasotransmitters as part of arsenic amelioration. Initial chapters
discuss the effects of arsenic on the plant genome and metabolome,
as well as the mechanisms behind the uptake and translocation of
arsenic in plants. The book then takes a deep dive into the role of
gasotransmitters, highlighting plant physiological responses. This
is an essential resource for students, researchers and agronomists
interested in plant physiology, biochemistry and plant hormones.
Botanists and seed collectors Rod and Rachel Saunders set out on what seemed to some to be an impossible mission – to find and photograph, in full bloom, all gladioli species found in South Africa and to collect and share their observations in a field guide. They had found all but one species before their untimely deaths at the hands of kidnappers in a forest in KwaZulu-Natal.
In the wake of this tragic event, friends and colleagues collaborated to keep the Saunders’ dream alive. This book is the result their collective efforts.
Gladioli are showy bulbous plants that fall within the Iris family, and the bulk of species are endemic to South Africa. Comprehensive and lavishly illustrated with more than 1,300 photographs, this guide covers the 166 Gladiolus species known to occur in the region.
The book is divided into seven taxonomic sections, according to the species’ distinguishing features. Each species is presented on a double-page spread, with a full plate of color photographs, including close-ups of diagnostic features, different color forms and habitats. Botanical descriptions cover identification (corm, cataphyll, spike, bracts, anthers, pollen, capsules, seeds, and scent), distribution, pollination, conservation status, and notes on ecology and the authors’ personal observations in the field. Distribution maps and flowering periods are given for each species, and tables highlight differences between similar-looking gladioli.
There are almost 300 recognized species, widely distributed across Africa, Europe and the Middle East, with more than half of the species found in southern Africa, making this book useful to botanists world-wide, as well as to horticulturist, propagators, students, gardeners and anyone with an interest in natural history.

Nanometal Oxides in Horticulture and Agronomy, a volume in the
Nanomaterial-Plant Interactions series, summarizes the
physiological, morphological, biochemical, and molecular regulation
of metal oxide nanoparticles in plants under normal conditions as
well as during different stresses. With a focus on impact and
applications, it presents the latest advances in the roles of metal
oxide nanoparticles in both horticulture and agriculture. Metal
oxide nanoparticles have been reported as beneficial inorganic
materials for the growth and development of plants, playing a
