Seed Dormancy in Grasses by G. M. Simpson Pdf

The first comprehensive review of the occurrence and explanation of seed dormancy in grasses is presented in this volume. An understanding of seed dormancy is of considerable significance to world agriculture and the global economy, since grasses are a principal source of food for humankind and play an essential role in stabilizing the land surface of much of the globe. Experimental evidence is considered in depth for a single species, the wild oat (Avena fatua), probably the most widely studied species for understanding seed dormancy in the plant kingdom. The evidence for this species is compared with other examples among the Gramineae to reach some general conclusions about the nature of seed dormancy in grasses.

Annual Plant Reviews, Seed Development, Dormancy and Germination by Kent Bradford,Hiro Nonogaki Pdf

The formation, dispersal and germination of seeds are crucial stages in the life cycles of gymnosperm and angiosperm plants. The unique properties of seeds, particularly their tolerance to desiccation, their mobility, and their ability to schedule their germination to coincide with times when environmental conditions are favorable to their survival as seedlings, have no doubt contributed significantly to the success of seed-bearing plants. Humans are also dependent upon seeds, which constitute the majority of the world’s staple foods (e.g., cereals and legumes). Seeds are an excellent system for studying fundamental developmental processes in plant biology, as they develop from a single fertilized zygote into an embryo and endosperm, in association with the surrounding maternal tissues. As genetic and molecular approaches have become increasingly powerful tools for biological research, seeds have become an attractive system in which to study a wide array of metabolic processes and regulatory systems. Seed Development, Dormancy and Germination provides a comprehensive overview of seed biology from the point of view of the developmental and regulatory processes that are involved in the transition from a developing seed through dormancy and into germination and seedling growth. It examines the complexity of the environmental, physiological, molecular and genetic interactions that occur through the life cycle of seeds, along with the concepts and approaches used to analyze seed dormancy and germination behavior. It also identifies the current challenges and remaining questions for future research. The book is directed at plant developmental biologists, geneticists, plant breeders, seed biologists and graduate students.

Seed Dormancy and Germination by Jose Carlos Jimenez-Lopez Pdf

Seed dormancy and germination are critical processes for the development of plants. Seed dormancy allows seeds to overcome harsh periods of seedling establishment, and is also important for plant agriculture and crop yield. Several processes are involved in the induction of dormancy and in the shift from the dormant to the germinating state, and hormones and regulatory genetic networks are among the critical factors driving these complex processes. Germination can be prevented by different factors leading to seed dormancy, which is highly dependent on environmental cues. During and after germination, early seedling growth is sustained by catabolism of stored reserves (proteins, lipids, or starch) accumulated during seed maturation, supporting cell morphogenesis, chloroplast development, and root growth until photo-auxotrophic growth can be resumed.

The Tallgrass Prairie Center Guide to Seed and Seedling Identification in the Upper Midwest by Dave Williams Pdf

Settlers crossing the tallgrass prairie in the early 1800s were greeted by a seemingly endless landscape of wildflowers and grasses, one of the most diverse ecosystems on our planet. Today, although the tallgrass prairie has been reduced to a tiny percentage of its former expanse, people are working to restore and reconstruct prairie communities. This lavishly illustrated guide to seeds and seedlings, crafted by Tallgrass Prairie Center botanist Dave Williams and illustrator Brent Butler, will insure that everyone from urban gardeners to grassland managers can properly identify and germinate seventy-two species of tallgrass wildflowers and grasses in eastern North Dakota, eastern South Dakota, southwestern Minnesota, southwestern Wisconsin, northern Illinois, northwestern Indiana, Iowa, eastern Nebraska, eastern Kansas, northwestern Missouri, and eastern Oklahoma. Williams has created a brilliant, nearly foolproof system of identification and verification. Two primary keys lead to eleven secondary keys that link to characteristic groups of tallgrass plants: seven groups for wildflowers and four groups for grasses. To identify a seedling, use the primary key to discover its place in the secondary key, then turn to that characteristic group to find your seedling. Circles on each full seedling photograph correspond to close-up photographs; triangles on these close-ups illustrate information in the text to further pinpoint identification. Drawings of leaves illuminate exact identification, and enlarged photographs of each seed provide yet another way to confirm identification. Thousands of seeds were sprouted in the Tallgrass Prairie Center’s greenhouse to provide seedlings close in size and development to those grown in the field near the end of their first season; research and photography took place over four years. Williams’s text for each species includes a thorough description, a comparison of similar species, and guidance for germination and growth. A complete glossary supports the text, which is concise but detailed enough to be accessible to beginning prairie enthusiasts. Anyone in the Upper Midwest who wishes to preserve the native vegetation of prairie remnants or reconstruct a tallgrass prairie of whatever size—from home gardens to schoolyards to roadsides to large acreages—will benefit from the hundreds of photographs and drawings and the precise text in this meticulously prepared guide.

East Africa’s grasses and fodders: Their ecology and husbandry by G. Boonman Pdf

The series Tasks for Vegetation Science is devoted to a variety of research aspects in vegetation science, pure as wellas applied. Of the applied problems one of the most pressing is to achieve better knowledge and improvement of the pasture vegetation in tropical and subtropical regions. As series editor I was impressed by the sheer volume of useful scientific information concerning pasture plants from East Africa collected during many years by Dr. Boonman and compiled in one manuscript. Dr. Boonman first came to East Africa in 1963 on an overland journey along the river Nile which took him from Alexandria in Egypt to Lake Victoria in Uganda and Kenya and back again. After a brief spell as a cotton agronomist in the Sudan Gezira he joined the grassland research team at Kitale, Kenya in 1966. Improvement ofseed yield oftropical grasses was his principal interest which finally led him into the fieldof breeding grasses. Well-known varieties from his work include Boma & Elmba Rhodesgrass as wellas Clone 13Elephantgrass. In 1979he was recalled to The Netherlands to head a cooperative seedcompany involved in the breeding of grasses and cereals. The author has focused this study on one region, Eastern Africa.Global application of theories runs into conflicts too easily with local types of farming, if not with bare economics. Very few books can be found that describe existing practices and seek local answers by digging deep in the stacks of old, local reports.

Flowering Plants. Monocots by Elizabeth A. Kellogg Pdf

This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa. Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales. This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.
