In horticulture, a keiki ( ) is a plant produced asexually by an orchid plant, especially ''Dendrobium'', ''Epidendrum'' (''sensu lato''), and ''Phalaenopsis'' orchids. The baby plant is an exact clone of the mother plant, sometimes flowering while still attached to the mother. The word ''keiki'' is Hawaiian for "baby" or "child", literally "the little one". *On a ''Phalaenopsis,'' a keiki is a small plant growing from one node along the flower stem. Keiki growth may be induced by prolonged exposure to high temperatures during the final phase of spike growth.〔Matthew Blanchard, Roberto Lopez, Erik Runkle, PhD, and Yin-Tung Wang, PhD ("Growing the Best Phalaenopsis" ), ''WWW.AOS.ORG'' ORCHIDS APRIL 2007〕 *On a ''Dendrobium,'' the keiki is typically found sprouting along the length of the cane or from the end of the cane. This is induced by the accumulation of growth hormones at that point, either naturally, or by the application of keiki paste. In addition to keikis which grow on flower spikes, ''Phalaenopsis'' may occasionally produce basal keikis at the base of the orchid. == Removing keikis == If a new plant is desired, the keiki should be left on the mother plant until it develops a healthy root system at least 3 inches long and has two or three leaves(for a ''Phalaenopsis'') or canes (''Dendrobium'').〔("Keiki's on an Orchid" ), ''rePotme.com''〕 For a ''Phalaenopsis'' keiki, this may take 6–12 months from when the keiki first forms.〔("Keiki propagation" ), ''EasyOrchids''〕 At this point, it can be carefully removed with a sharp knife and planted in its own pot. * Keikis are cut below and above the stem, leaving a small piece of stem on the baby plant. A separated keiki can be expected to flower in approximately the same amount of time it would take for the cross or species to flower from a seedling. Some species orchids like ''Phalaenopsis pulchra'' frequently produce keikis, which flower while still attached to the mother plant. If a new plant is not desired, the keiki can be removed at any time. Removing the entire inflorescence after flowering is complete can prevent the production of keikis and result in a "tidier" appearance for the plant. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「keiki」の詳細全文を読む スポンサード リンク
