Abstract :テッポウユリひのもとのりん片を材料として切断処理およびりん片の母球内における着生位置と子球形成の関係を調査した。1.りん片の母球内における着生位置が中心部から外側になるにつれ子球形成数, 子球重はそれぞれ増加した。その増加の傾向として次の関係式が得られた。Y_1=0.497X+1.307 Y_2=0.814X-0.264ここにY_1=形成子球数 Y_2=子球重X=りん片の母球内における中心部よりの着生位置2.りん片を横に2切, 3切, 4切したものについてはいずれの場合にも基部の切片からの子球形成数が多くまた子球重も重かった。
Experiments were carried out to investigate the formation of bulblets from scale leaves of Liliun longiflorum Thunb.Hinomoto,with spacial reference to the position of scales in the mother-bulb, and also to the cutting procedure of scales into pieces. 1. As the position of scales in the mother-bulb became to be localized towards the outer part of the mother-bulb, much more abandance in number and larger sized bulblets have resulted. The following regression equations were obtained for the relationship between the position of scales in the mother-bulb (X) and the number of bulblets (Y_1) produced from those scales, as well as the fresh weight of bulblets formed (Y_2); Y_1=0.497X+1.307 Y_2=0.814X-0.264 2. When the scales were cut transversally itno half, third, or fourth pieces, respectively, the newly formed bulblets sprouted from those severed pieces showed definte increase in their numbers and sizes according to the relative position of the severed pieces on the mother scale, extending from the distal to the proximal end of the scale.
