Conservation and Management of Plant Genetic Resources in Nagano Prefecture, Japan
Get PDFThe current status of ex situ/in situ conservation of plant genetic resources for food and agriculture (PGRFA) and issues related to their management was surveyed in Nagano Prefecture. Genetic resources from numerous PGRFA landraces and local varieties have been collected by the Gene bank Project to date.However,most of these varieties have disappeared,particularly those of major cereals and grain legumes, due to changes in agriculture and rural/modern lifestyles.Formalization of the seed-production system from a local system to a larger-scale seed system, combined with initiatives like the ‘Shinshu traditional vegetable’certification system would facilitate the conservation of PGRFA at the farm level.本報告では，長野県における作物遺伝資源の保全状況とその課題について議論した。長野県では，これまでに多くの在来系統や地方品種がジーンバンクプロジェクトによって調査収集されてきた。しかしながら，それらの多く，特に主要穀類やマメ類では，農業を取り巻く環境や生活様式の変化が原因で失われてしまっている。種子生産システムの転換や「信州伝統野菜」認定制度が，今後の農家レベルでの作物遺伝資源の保全を後押しすると考えられる。Article信州大学農学部紀要 48（1-2）: 85-92(2012)departmental bulletin pape
Use and Conservation of Edible Wild Plants in Bhutan
Get PDFIn an investigation of edible wild plants in Bhutan by the authors, plants samples were identified and categorized into 60 families and 172 species and 6 families and 18 species from Divisions Magnoliophyta and Pteridophyta,respectively.Management of the community forest is one effective way for achieving in-situ conservation of edible wild plants. Since gathering edible wild plants in a forest is performed simultaneously with the maintenance and management of the forest in Bhutan, gathering is thought to be helpful to forest conservation.ブータンでの食用野生植物の調査の結果，種子植物で60科172種が，シダ植物で６科18種が確認された。共有林を維持管理していくことは，このような野生植物の生息域内保全に効果的である。ブータンでは食用野生植物の採取は森林の維持管理と一体的に行われているため，森林保全の一助にもなっていると考えられる。Article信州大学農学部紀要 48（1-2）: 75-83(2012)departmental bulletin pape
Comparison of seasonal growth and yield performances of Japanese cabbage varieties in Nagano, Japan
Get PDFThree cabbage varieties, "Ajioh","Shutoku SP" and "Shinshu 868" were investigated at the AFC field, Faculty of Agriculture, Shinshu University during 2014. The experiment was established in a simple Randomized Complete Block Design, where these three cabbage varieties were transplanted and harvested at five different seasons. There were some significant differences among the varieties in head weight, head width and head height, as well as the number of leaves and their weight. For seasonal difference, the highest growth and yield performances were observed in Phase 3 (harvested in October) among the varieties. The results obtained indicated that "Shinshu 868" produced the highest head weight (1.64㎏) and the highest head width (19.1㎝) ; while "Ajioh" produced the highest head height (14.4㎝/head). The phase 5 had no head formation due to change in weather condition from October to December.Article信州大学農学部AFC報告 13: 131-136 (2015)departmental bulletin pape
