Conservation and Enhancement of Natural Resources

Meeting food and livelihood security needs in developing countries will require the conservation and enhancement of natural resources that contribute to agricultural production. Chief among the resources to be sustainably managed are soils and forests. Failure to protect and improve soils will lead to dramatic decreases in domestic agricultural production and consequent dependence on imported f...

Conservation of Tropical Forage Genetic Resources

Tropical forage genetic resources are essential material for the development of adapted pasture crops. Collection, conservation and characterization of these resources are needed to preserve them for future generations. Collections were made after 1970 by CIAT, CSIRO and ILRI. The current status of these collections and present conservation methods are reviewed. Genetic diversity has been asses...

Collecting pollen for genetic resources conservation 25

Pollen grains are the mature male (haploid) gametophyte of higher plants. These tiny organs (10-100 IJ.m in diameter) develop in the anthers (Stanley and Linskens, 1974). When the flower opens the anthers become exposed to the environment and dehydration triggers a mechanism for release of the pollen. In the process, the pollen also dehydrates. Though the pollen of most species can withstand dr...

Poultry Genetic Resources and Conservation Biology

Recent generations of poultry students and poultry specialists generally seem to lack awareness of the vast genetic diversity which has accumulated in the domestic birds. This diversity has tended to become segregated within the realms of special purpose and special group such as industrial breeders and producers. There are many variants and variation in relation to species, body systems, and p...
