Studies on the Leaf Development of the Scale Bulblet in the Easter Lily (Lilium longiflorum Thunb.)
Year: 1978
Type: article
Abstract: The experiments were carried out to clarify the effects of hot water treatments, the size of the parent scale, or the position of the parent scale in the parent bulb, upon the leaf emergence of the scale bulblet as well as the survival of the parent scale in the Easter lily cv. ‘Hinomoto’.The bulbs were treated with 45°C water for 30min. prior to scaling. The parent scales were planted in sandy soil on Aug. 7, 1975 or July 27, 1976 and grown until the last examination on Dec. 21, 1975 or Jan. 19, 1977, respectively.Leaves emerged more rapidly on the scale bulblets from the small parent bulb than on those from the large ones. The hot water treatment on the large parent bulb remarkably promoted the leaf emergence of the scale bulblets. In light scaling, the leaf emergence was most rapid on the inner scales and latest on the outer ones. In dark scaling, however, it was most rapid on the middle scales and latest on the inner ones.The hot water treatment did not obviously affect the survival of the parent scales. Their survival rate was higher in dark scaling than in light scaling. The survival rate of the parent scales from large bulbs was higher than that from small ones. Independent of the scaling depth or the size of the parent bulb, the survival rate was highest on the inner scale and was lowest on the outer one.
