Available in PDF, EPUB and Kindle. Book excerpt: Osmanabad is the southernmost district Maharashtra State situated between 17° 35' and 18° 40' north latitude and 75° 16' and 76° 40' east longitude. Palynology is one of the most widely used research tools in Quaternary studies (Edwards 1983). As Osmanabad district having very less forest cover, researchers have shown little interest in botanical studies in this region. Very few workers like Naik (1979, 1998) worked on floristic studies, but nobody worked on pollen morphological studies for this region. In the last century, Brown (1958), Frisch (1953) and Hooker (1897) have contributed to our knowledge of pollen and spore morphology. In the present century, rapid progress has been made in the study and several thousands of pollen and spores have been described and illustrated (Davis 1963). Study of pollen diversity has received an enormous attention since last few decades due to its allergenic properties. Identification of allergenic pollen grains is necessary from the plants those are utilized as ethnomedicinal, ethnovegetables, etc. This was the sincere attempt to note diversity of pollens in relation to taxonomy, allergenic properties and its economical importance in the region.

This book was released on 2000 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication presents the proceedings a meeting organized and implemented by the Asia & Pacific Seed Association and the Department of Agricultural Extension of the Ministry of Agriculture in Bangkok, Thailand in close collaboration with the Seed and Plant Genetic Resources Service of the FAO. In line with the Rome Declaration on World Food Security and the World Food Summit Plan of Action, the Meeting recognized that one of the major challenges facing most countries in Asia and the Pacific is the need to invest significant resources into strengthening their capacity to increase the availability of good quality seeds of a wider range of plant varieties. This will contribute to the maximization of both agrobiodiversity and productivity, in order to achieve national food security while reducing environmental degradation and the depletion of natural resources. The Meeting proposed and agreed to establish a regional seed network to facilitate the exchange of information and expertise among countries and to coordinate policies and programmes designed to strengthen and improve local seed production and distribution systems in Asia and the Pacific. The Seed Network for Asia and the Pacific (SNAP) will facilitate inter-country scientific and technical collaboration on seed production and supply, and promote crop genetic resources evaluation, conservation and utilization in the region.

This book was released on 1974-04-25 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: An account of the evolution and principles involved in breeding crops grown in the tropics. This book developed from a symposium held in New Delhi in 1970 at the Indian Agricultural Research Institute. It begins with a consideration of the history of agriculture. Recent techniques make is possible to set crop plant evolution against the time scale of agricultural development, enabling the rate of evolution to be determined with some precision. Throughout the account the studies stress the range of material and changes and improvements in crops, with special reference to their importance not only in the tropics, but also to world agriculture. This book brings to the notice of geneticists and breeders in western countries the work undertaken in India in elucidating the evolution and recent improvement of crop plants of world wide importance. It is also an authoritative account for students of plant breeding in the tropics taking courses in universities, in institutes and colleges of agriculture who need to have within the covers of one book a comprehensive, yet concise text that clearly sets out the principles involved in the breeding of crops grown in the tropics.

Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).
Download or read book Climate Resilient Horticulture Adaptation and Mitigation Strategies written by Harish Chandra Prasad Singh and published by Springer. This book was released on 2016-08-23 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change, a global phenomenon, has attracted scientists to contribute in anticipatory research to mitigate adverse impacts, which are more important for horticulture, considering that the scenario is in the midst of revolution, reaching the production level of 250 million tonnes in India. Impacts of climate variability have, invariably, profound influence on production and quality. An understanding of the impacts and relevant adaptation strategies are of foremost importance to sustain the productivity and profitability of horticulture crops in the climate change scenario, which necessitates synthesis of current knowledge to develop strategies for adaptation and mitigation to achieve climate-resilient horticulture. The book Climate-resilient horticulture: adaptation and mitigation strategies addresses the effects of climate change on different horticultural crops and focuses on the adaptation strategies based on the scientific knowledge generated by the experts in different agro-climatic regions in India. Issues have been covered in various chapters to make this book a treasure of knowledge in horticulture vis-a-vis climate change. Some of the crops included in the book are apple, grapes, cashew, banana, litchi, mango, coconut, oil palm, potato, tomato, cucurbits and flowers. In addition to strategies to be adapted in these crops, various other important aspects like carbon sequestration, pests and diseases, and urban landscaping are also covered in the book. Information on climatic risks and adaptation options for resilience in horticultural crops and future strategies and information on pest and disease dynamics on horticultural crops in relation to climate change and available mitigation strategies have also been documented. The book is edited by Dr H P Singh, a visionary leader, and his colleagues, which will be highly valuable to research workers, students, policy planners and farmers to understand and checkmate the adverse effect of climate change, so as to convert weakness into opportunity.

Available in PDF, EPUB and Kindle. Book excerpt: The book is a compilation of research work carried out on plant viruses during past 100 years in India. Plant viruses are important constraints in Indian agriculture. Tropical and sub-tropical environments and intensive crop cultivation practices ideally favours perpetuation of numerous plant viruses and their vectors in India, which often cause wide spread crop losses. Of all the plant pathogens, studies of plant viruses have received a special attention as they are difficult to manage. A large body of literature has been published on the plant virus research from India during past 100 years; however the information is so far not available in one place. This book provides comprehensive information on the biology, molecular biology, epidemics, crop losses, diagnosis and management of viruses and viroids occurring in India. Description of properties of the viruses are provided in the chapters comprising of different genera such as Allexivirus, Begomovirus, Babuvirus, Badnavirus, Carlavirus, Carmovirus, Cucumovirus, Closterovirus, Ilavirus, Mandrivirus, Potyvirus, Tospovirus, Tungrovirus and Sobemovirus. Virus-vector research related to aphid, thrips and whitefly is discussed. The work on the management aspects of plant viral diseases has been described with reference to the conventional, antiviral and transgenic approaches. Further, the quarantine mechanism developed in India for the exclusion of viruses and vectors has also been included. The book also provides useful information about the capacity building on the research and education on Plant Virology in India. Overall, the book covers a wide range of accounts of research findings and innovations in Plant Virology in India during past 100 years. The book will be a resourceful reference to the students, scientists, agricultural professionals and policy makers.
