Book excerpt: Rhadinaphelenchus cocophilus incited red ring disease when inoculated artificially into stem, leaves, or roots of coconut pains between 3-10 years old. Inoculation was effected by inserting fragments of diseases tissue or a water suspension of the nematode into holes made in the tree at the sites mentioned above. Nematodes also penetrated intact tissue of leaf axils, petioles and roots. External symptoms appeared 40-70 days after inoculation and trees were dead in six to eight weeks after symptoms first appeared. The coconut does not become naturally infested but green nuts were successfully infested artificially both on trees and in the laboratory. The epicarp of infested nuts became brown, hard and shrivelled. The mesocarp became reddish brown and containedliving nematodes. The nematodes did not pass from infested to healthy nuts through the fruit stalk. R. cocophilus is found intercellularly and intracellularly in the ground parenchyma of infested tissue. Some cells disintegrate forming cavities in which nematodes are abundant. Many of the cells in the infested tissue lose their contents. The nematodes tend to migrate to areas with living cells. Adults and eggs are in greater numbers in the crown region of trees where lesions terminate in elongate streaks and dots of orange colored tissue. Nematodes do not invade xylem vessels nor damage them directy. However, the vessels which pass through the discolored areas become occluded with tyloses and as result the water conducting system of infested trees become...

Available in PDF, EPUB and Kindle. Book excerpt: Nematode interactions are important biological phenomena and of great significance in agriculture. It is a fascinating subject which is multidisciplinary by nature, and concerns any scientist involved with plant health. There have been marked advances in our knowledge of various aspects of the subject in the last two decades. This study area has been the subject of several reviews, but there was no exclusive text on the subject. This has stressed the need to document the information, developing a unifying theme which treated nematode interactions in a holistic manner. This book is about the inter action of plant-parasitic nematodes with other plant pathogens or root symbionts, the nature of their associations, their impact on the host and con sequential interactive effects on the involved organisms. Since nematodes are at the centre of the theme, the responsibility of understanding of other plant pathogens dealt with in this book is largely delegated to the reader. I have limited the book content to interactions with biotic pathogens and root symbionts only, for various reasons. The book embodies 16 chapters, and attempts to present balanced infor mation on various aspects of nematode interactions with other plant pathogens and root symbionts. Some chapters describe general aspects of the subject. Interactions of nematodes with specific groups of organisms are addressed in the remaining chapters.

This book was released on 2019-02-15 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of "The coconut palm - A monograph" in 1960, considerable information has been accrued on the crop through work at research institutes, international organisations and development agencies. Although coconut cultivation is spread over 93 countries, providing employment and creating livelihood opportunities to 64 million families around the globe, smallholder coconut farmers are now facing numerous challenges. The wide gap between the potential and actual yield is a major concern, and as such it is necessary to disseminate knowledge in order to implement research findings. Coconut research in India, one of the leading coconut producing countries, is celebrating its centenary, making this an opportune time to review the research and development advances and the relevant technologies. This detailed, comprehensive book covers all aspects of coconut, from the origins to cultivation, breeding, physiology and value addition, as well as subjects of topical interest like nutrition and health, biotechnology, and climate change and carbon sequestration. Written by leading experts in the fields it emphasises that the livelihood of the small coconut landholders is the ultimate aim of scientists and developmental agencies, and outlines various important strategies to make coconut farming more remunerative globally. It discusses work in all the major coconut growing countries and outlines suggestions for international cooperation. Research work on the crop is comparatively difficult because of its perennial nature, longevity, height, long juvenile phase, large sized nuts, cross pollination and seed propagation. As these special features necessitate greater investment of resources, time and land, it is all the more imperative that research is not duplicated and the information and experience becoming available around the world is shared so that it can be fully utilised. In this context periodic publications, compiling all the available information on coconut assume greater significance. This book is therefore of great value to researchers, students, extension workers, developmental agencies and progressive farmers.
