Abstract :カトレヤ(Lc. Princess Margaret × Lc. Bonnanza Giant)の幼苗を材料にして, 初期生育に対する炭素源の及ぼす影響を調査した。糖の種類については, ショ糖, 果糖, ブドウ糖, デンプンをそれぞれ2.0%の濃度で比較し, さらに, ろ過滅菌して添加したショ糖の濃度の及ぼす影響を2.0%から0%までの5段階で調査した。1.幼苗の生育に対するショ糖の濃度の影響については, 2.0%区が最もよく, 濃度が減少するにつれて, 生育が不良になることが確かめられた。2.糖の種類の影響については, ショ糖と果糖は同程度によく, ブドウ糖, デンプンについては, 両者とも炭素源としての利用は不適であると判断された。
Attempts to clear the effects of concentration of sucrose and various carbon sources on the growth responses of cattleya (Lc. Princess Margaret × Lc. Bonnanza Giant) seedlings, were made using the aseptic culture techniques. As the source of carbon, sucrose, fructose, glucose and starch were used at 2.0% concentration respectively. In addition, five level of concentrations (from 2.0% to 0%) were tested with sucrose medium using the filter sterilization techniques. 1. The most favorable growth of seedlings were obtained in the media contained 2.0% sucrose and the poor growth were obserbed according to decrease of concentration. 2. In the medium containing sucrose and fructose the seedlings showed fairly excellent growth but in the medium containing both glucose and starch those seedlings not showed good growth responses.
