This book was released on 1963 with total page 210 pages. Available in PDF, EPUB and Kindle. 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...

Book Synopsis The Coconut Palm (Cocos nucifera L.) - Research and Development Perspectives by : V. Krishnakumar
Download or read book The Coconut Palm (Cocos nucifera L.) - Research and Development Perspectives written by V. Krishnakumar and published by Springer. This book was released on 2019-02-15 with total page 834 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.

Download or read book General Nematology written by A. Maggenti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is an overall view of nematology because I believe the science should be treated as a unified discipline. The differences in the biological habits of nematodes do not justify the separation of plant nematologists and animal nematologists, since the separation is not a reflection of any difIerences inherent to nematodes. Therefore, the book is arranged with a format that in the beginning chapters illustrates the similarities and se- quence of development of morphological characters among nematodes regardless of their biological habits. The later chapters illustrate the in- tegration of the evolutionary development of the parasitie habit from related free-living forms. Nematology is probably the last major discipline to establish its inde- pendence from the parent science of zoology. This natural evolvement of nematology has occurred because of the overwhelming accumulation of sophisticated information and research that reflects the unique relation- ships of nematodes to other forms of plant and animal life as weH as their relationships in other facets of the environment.N ematodes are inverte- brate animals that, like insects, are unusual in their great numbers and varieties, their smaH size (generally microscopic), their high degree of internal organization, and their virtually ubiquitous distribution. They oc- cupy almost every ecological niehe, often causing disease of humans, other animals, and plants. These activities often result in debility, death, or in the impairment and loss of food supply with consequent loss to producers and consumers.
