| 内容記述 | Rooting ability was investigated of the softwood cuttings taken from different positions of the current basal shoots at the early stage of growth in Spiraea thunbergii SIEB. The results were as follows. 1. Cuttings were taken from the shoots 50-60 cm in length on May 10, 1979. After the cutting base was dipped into 20 ppm NAA solution for 20 hours, they were inserted in the rooting medium (coarse vermiculite) on the bed covered tightly with vinyl film. The medium temperature was kept at 20-22℃ but the air temperature under the film varied from 20 to 30℃ during the experiment. The data was taken after three weeks. The cuttings from the middle and upper position (except the shoot tip) of the shoots survived more and rooted earlier than those from the basal position. The number of roots per cutting was more in the former than in the latter. 2. When cuttings were taken from 35-45 cm shoots and handled in the same way as mentioned above, the basal cuttings survived much more than the terminal ones. Rooting was promoted in the former but retarded in the latter. The cuttings of which proximal ends were not cut with knife rooted similarly to those with adjusted proximal cut surface. 3. Dipping the base of basal and terminal cuttings taken from 35-45 cm shoots into 20 ppm NAA solution resulted in early and heavy rooting. However, the treatment decreased the number of survived cuttings to some extent. 4. The basal cuttings taken from 20-25 cm shoots rooted similarly to those taken from the same position of 35-45 cm shoots. | |||||||||||||||||||||||

| 内容記述 | ユキヤナギのさし木繁殖に最も適するさし穂を得るため, 1979年5月10日に, 母株の地際から発生した成熟度の異なる新梢から採穂し, バーミキュライト床に密閉ざしを行った. 3週間後の調査結果は, 以下の通りであった. (1) 50-60cmの新梢から採穂した時, 頂端を除き, 中・上部からのさし穂は多くの根を早く発根し, 下部からのさし穂の発根は劣った. (2) これと異なり, 35-45cmの新梢から採穂した時は, 基部からのさし穂が, 早く, しかも多く発根し, 頂部からのさし穂の発根が劣った. (3) 20-25cmの新梢の基部から採穂する時, さし穂基部はそのままでも, あるいは切り返されても, 発根状態に差がなかった. (4) NAA処理は, 発根までの所要時期を短縮し, 斉一な発根を促がし, さし穂あたりの発根数を増加させたが, さし穂の枯死を促進する傾向があった. | |||||||||||||||||||||||
