- irradiation of red light irradiation was performed using a brand name: CCFL light source unit and a manufacturer name: Nippon Medical Chemical Co., Ltd. as a light irradiation device.
- Example 5 Culturing was carried out in the same manner as in Example 3 except that a medium not containing an adventitious root formation promoter was used. The results are shown in Table 3.
- the adventitious root rooting promoter of the present invention exhibits an excellent rooting effect regardless of the plant species, particularly even in extremely difficult rooting lines.

Abstract
Description
〔1〕アバミンを含む植物の不定根形成促進剤。
〔2〕上記〔1〕に記載の不定根形成促進剤を含有する、植物のシュートの発根用培地。
〔3〕植物のシュートを上記〔1〕に記載の不定根形成促進剤の存在下栽培し、前記シュートから発根させる、クローン苗の生産方法。
〔4〕植物のシュートを上記〔2〕に記載の発根用培地にて栽培し、前記シュートから発根させる、クローン苗の生産方法。
不定根形成促進剤を含む発根用培地で植物を培養する場合、発根用培地中の不定根形成促進剤の濃度は、好ましくは約0.01μM以上約100μM以下、さらに好ましくは約0.1μM以上約10μM以下、とりわけ好ましくは約0.5μM以上約5μM以下である。
本発明では、植物のシュートを、不定根形成促進剤の存在下栽培することにより、前記シュートから発根させることができる。その理由は不明であるが、以下比較例として示すように、アバミンSGでは、アバミンと構造が近似するにもかかわらず発根作用が認められないことから、不定根形成促進剤による発根促進作用は、アバミンとアバミンSGの共通の作用であるアブシジン酸合成阻害作用ではなく、他の作用によると推察される。
挿し穂の材料として、ユーカリプタス・グロビュラス(Eucalyptus globulus、以下、単にE.グロビュラスと略記する。)の難発根系統であるユーカリクローンA(G-004)を用いた。すなわち採穂母樹から、5~20cmの長さ、節が1~3節、葉が2~6葉程度に伸長した穂木を切り出し、挿し穂を調製した。
不定根形成促進剤を添加しない培地を用いた以外は実施例1と同様にして培養を行った。結果を表1に示す。
挿し穂の材料として、E.グロビュラスの超難発根系統であるユーカリクローンB(WA-002)を用いた以外は実施例1及び比較例1と同様にして培養を行った。結果を表2に示す。
不定根形成促進剤を添加しない培地を用いた以外は実施例2と同様にして培養を行った。結果を表2に示す。
材料として、チャ(Camellia sinensis)の一品種を用いた。チャの採穂母樹から、5~20cmの長さ、節が1~3節、葉が2~6葉程度に伸張した穂木を切り出し、挿し穂を調製した。
不定根形成促進剤を添加しない培地を用いた以外は実施例3と同様にして培養を行った。結果を表3に示す。
