Although tree- and stand-level estimates of forest water use are increasingly common, relatively little is known about partitioning of soil water resources among co-occurring tree species. We studied seasonal courses of soil water utilization in a 450-year-old Pseudotsuga menziesii (Mirb.) Franco-Tsuga heterophylla (Raf.) Sarg. forest in southwestern Washington State. Soil volumetric water cont...

2. At its Fourteenth Session (2013), the Commission endorsed the Genebank Standards for Plant Genetic Resources for Food and Agriculture, contained in this document. The Genebank Standards were originally endorsed by the Commission in 1993. In 2009, the Commission requested FAO to revise the Genebank Standards in cooperation with the relevant international organizations to ensure up-to-date con...

This document has been prepared at the request of the Secretariat of the FAO Commission on Genetic Resources for Food and Agriculture, and in close collaboration with the FAO Plant Production and Protection Division, to facilitate the Commission’s deliberations when it will review key issues on targets and indicators for plant genetic resources for food and agriculture at its Fifteenth Regular ...

This study aims to explore the information on miscellaneous uses on plant resources found in Parroha VDC of Rupandehi district, Nepal. The study was conducted during May 2007. Informations on plant resources were collected interviewing key informants using a semi structured open ended questionnaires. Altogether 33 different species of plants belonging to 19 families were found used for miscella...

Indigenous plant resources provide rural communities with non-timber forest products that provide energy, food, shelter and medicine. Indigenous plant users in the rural communities have developed selective management methods to sustain plant resources. The most common management methods are restrictions on the cutting of green plants, harvesting of some species during certain seasons, exclusiv...

Invasive alien plants can compete with native plants for resources, and may ultimately decrease native plant diversity and/or abundance in invaded sites. This could have consequences for native mutualistic interactions, such as pollination. Although invasive plants often become highly connected in plant-pollinator interaction networks, in temperate climates they usually only flower for part of ...

Maize is highly genetically and phenotypically diverse. Tropical maize and teosinte are important genetic resources that harbor unique alleles not found in temperate maize hybrids. To access these resources, breeders must be able to extract favorable unique alleles from tropical maize and teosinte from their population J. B. Holland ( ) · S. Sood Department of Crop Science, North Carolina State...

Cryopreservation is becoming a very important tool for the long-term storage of plant genetic resources and efficient cryopreservation protocols have been developed for a large number of plant species. Practical procedures, developed using in vitro tissue culture, can be a simple and reliable preservation option of potato genetic resources rather than maintaining by vegetative propagation in ge...

The National Institute of Agrobiological Sciences (NIAS) is implementing the NIAS Genebank Project for conservation and promotion of agrobiological genetic resources to contribute to the development and utilization of agriculture and agricultural products. The project's databases (NIASGBdb; http://www.gene.affrc.go.jp/databases_en.php) consist of a genetic resource database and a plant diseases...
