Download or read book Pollination in Plants written by Phatlane William Mokwala and published by BoD – Books on Demand. This book was released on 2018-06-06 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are the basic source of food for both humans and animals. Most of the food is made of fruits and seeds. For these to be formed, pollination must first take place. This process is the transfer of pollen grains from the anther, which is the male structure of the flower, to the sigma on the female structure of the flower. The transfer process requires agents to be carried out. The agents can be either biotic or abiotic. Nature perfected this arrangement between the pollination agents and the plants. As ecosystems and agricultural systems are changing, this balanced arrangement becomes disturbed. This makes it necessary that pollination systems be studied so that necessary measures can be undertaken to ensure productivity. The chapters of this book present results in research undertaken to improve productivity in crops such as Actinidia chinensis (the kiwifruit), Theobroma cacao (cocoa), and Manicaria saccifera (a tropical forest palm). Some results are presented on tests to check the viability of pollen grains and the delivery of sperm cells through pollen tubes to the embryo sac. These results can serve as guidelines to any person seeking to improve pollination and productivity or to check the efficiency on pollination in ecosystems or agricultural production systems.

This book was released on 2013-06-29 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a great honor and indeed a privilege for me to write the Foreword to this book, the first of its kind from the Forest Products Research Institute The study of forest insects is now becoming a matter of great concern to many people all over the world because insects damage the already depleted forests and forest resources. In Ghana very little interest was shown in the insects of forest trees and products. But as forest practices have become more intensive so also have the pests on the crops increased and the damage caused increased to alarming proportions. Foresters are now becoming in creasingly aware of the immense havoc that some of these insects can cause. To aid the fight against the pests they have to be fully identified and studied so that effective control measures can be implemented. It is in an effort to bridge this gap in our knowledge that one welcomes this book by Professor Michael R. Wagner, Dr. S.K.N. Atuahene and Dr.

Download or read book Cacao Diseases written by Bryan A. Bailey and published by Springer. This book was released on 2016-02-22 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the current state of knowledge concerning cacao pathogens and methods for their management. Topics discussed include the history, biology and genetic diversity of Moniliophthora species (which cause witches’ broom and frosty pod rot) and Phytophthora species (which cause black pod rot) that cause diseases resulting in major losses to cacao production. Emerging pathogens such as Cacao swollen shoot virus and Ceratobasidium theobromae (which causes vascular streak dieback) are also discussed in detail, along with many pathogens of significant local concern. Most of these pathogens represent major risks to global cacao production should they expand into new areas, breaking out of their current limited distributions. By considering cacao diseases as a group, similarities in the available tools and techniques used in their management become apparent, as do their limitations. Gaps in our current knowledge of cacao pathogens and the management of the diseases they cause are detailed, and suggestions for future research directions are provided. This insight allows readers to consider cacao disease threats from a more comprehensive, global perspective and paves the way for an improved synergy of efforts between the various research programs, agencies, and industries, both private and public, with vested interests in cacao production, and cacao farmers.
