PROBLEM TO BE SOLVED: To readily investigate and find out a vigorous greening plant which is native to Japan and can maintain the domestic unique landscape, develop a mass propagation technique of the plant, and further provide a new greening technique which is well-adapted thereto and can efficiently propagate and provide the greening plant in a short time.SOLUTION: In a mass propagation method of Chrysanthemum pacificum seedlings, a seedling P of Chrysanthemum pacificum having the same wood rotting fungus as the habitat is grown under proper control (steps 1-5 in Fig.1), and seedlings P of Chrysanthemum pacificum having the same wood rotting fungus as the habitat and/or other microorganisms are obtained from normal buds B of the Chrysanthemum pacificum C (steps 6-10 in Fig.1). The steps of growing the seedlings P of Chrysanthemum pacificum under control in a proper environment, rooting normal buds B of the grown Chrysanthemum pacificum C over a predetermined time, and growing a large amount of seedlings P of Chrysanthemum pacificum having the same wood rotting fungus as the habitat and/or other microorganisms under control in the proper environment (steps 2-9 in Fig.1) are repeated for propagation.COPYRIGHT: (C)2013,JPO&INPIT【課題】 日本原産で国内固有の景観を維持でき、強い生命力をもつ緑化植物を逸早く調査・発見すると共に、その植物の大量増殖技術を開発し、それに良く適合し、当該緑化植物を効率的に短期間にて大量に繁殖、提供することができる新たな緑化技術を提供する。【解決手段】 自生地と同じ材木腐朽菌をもつイソギク苗Pを適宜管理・育成し(同図1中の1、~5)、そのイソギクCの定芽Bから、自生地と同じ材木腐朽菌および/または他の微生物をもつイソギク苗Pを得る(同図1中の6,~10)ようにし、該イソギク苗Pを適宜環境下に管理して育成し、成長したイソギクCの定芽Bを、所定時間かけて発根させ、自生地と同じ材木腐朽菌および/または他の微生物をもつ大量のイソギク苗Pを、適宜環境下に管理して育成するという工程(同図1中の2,~9)を繰り返し、繁殖を行うようにしてなるイソギク苗の大量繁殖方法である。【選択図】 図1
