Notes
Bolting and scaly leaf emergence of Easter lily bulblets were investigated in the scaling fields for commercial bulb production. Leaf emergence ratio and bolting one were presented as the ratio of scale bulblets with leaves to the whole ones belonging to the investigated plot and as the ratio of bolted bulblets to scale bulblets provided with leaves, respectively. Findings are as follows; 1) Bolitng ratio was over 80% with most of plots. 2) There could not be observed any differences at all among cultivars, scaling localities, dates of scaling as well as among kinds of soil texture. 3) In a few plots there was a tendency that a low leaf emergence ratio accompanied a low bolting ratio, and in other plots, the higher one the higher bolting ratio. 4) Scaly leaves appeared quite abundantly in cases where scales or bulblets had been half and/or fully exposed to the air in nursery beds. From these facts it is duly suggested that the scaly leaf emergence will occur comparatively earlier than the bolting, and also that the darkness can promote the bolting, and the light will, in turn, hasten the scaly leaf emergence.
りん片繁殖によるテッポウユリの球根生産を目的とした圃場を対象とし,仔球の抽台およびりん片葉発生の実態を調査し,これらの発生と外的条件との関係を調べた.ほとんどの圃場で80%以上の抽台率がみられ,品種,調査地,植付け期,土性による差異は認められなかつた.出葉率の低い区では抽台率が低く,出葉率の高い区では逆にそれが高くなる傾向がみられた.また,りん片葉の発生は仔球や母りん片が地表に露出している場合に多い傾向が認められた.これらの事実から,りん片葉の発生は相対的に抽台より早くおこること,母りん片を浅植えして地表に露出させることによつて,りん片葉の発生が促進され,またりん片葉の割合も多くなるのに対し,深植えすることによつて抽台が期待されることが明らかである.
